›BACKGROUND OF THE INVENTION · 1 of 2
Retinoic acid-related nuclear receptor gamma t (RORγt) is a nuclear receptor, exclusively expressed in cells of the immune system, and a key transcription factor driving Th17 cell differentiation. Th17 cells are a subset of CD4 + T cells, expressing CCR6 on their surface to mediate their migration to sites of inflammation, and dependent on IL-23 stimulation, through the IL-23 receptor, for their maintenance and expansion. Th17 cells produce several proinflammatory cytokines including IL-17A, IL-17F, IL-21, and IL-22 (Korn, T., E. Bettelli, et al. (2009). “IL-17 and Th17 Cells.” Annu Rev Immunol 27: 485-517), which stimulate tissue cells to produce a panel of inflammatory chemokines, cytokines and metalloproteases, and promote recruitment of granulocytes (Kolls, J. K. and A. Linden (2004). “Interleukin-17 family members and inflammation.” Immunity 21(4): 467-76; Stamp, L. K., M. J. James, et al. (2004). “Interleukin-17: the missing link between T-cell accumulation and effector cell actions in rheumatoid arthritis” Immunol Cell Biol 82(1): 1-9). Th17 cells have been shown to be the major pathogenic population in several models of autoimmune inflammation, including collagen-induced arthritis (CIA) and experimental autoimmune encephalomyelitis (EAE) (Dong, C. (2006). “Diversification of T-helper-cell lineages: finding the family root of IL-17-producing cells.” Nat Rev Immunol 6(4): 329-33; McKenzie, B. S., R. A. Kastelein, et al. (2006). “Understanding the IL-23-IL-17 immune pathway.” Trends Immunol 27(1): 17-23.). RORγt-deficient mice are healthy and reproduce normally, but have shown impaired Th17 cell differentiation in vitro, a significantly reduced Th17 cell population in vivo, and decreased susceptibility to EAE (Ivanov, II, B. S. McKenzie, et al. (2006). “The orphan nuclear receptor RORgammat directs the differentiation program of proinflammatory IL-17+T helper cells.” Cell 126(6): 1121-33.). Mice deficient for IL-23, a cytokine required for Th17 cell survival, fail to produce Th17 cells and are resistant to EAE, CIA, and inflammatory bowel disease (IBD) (Cua, D. J., J. Sherlock, et al. (2003). “Interleukin-23 rather than interleukin-12 is the critical cytokine for autoimmune inflammation of the brain.” Nature 421(6924): 744-8; Langrish, C. L., Y. Chen, et al. (2005). “IL-23 drives a pathogenic T cell population that induces autoimmune inflammation.” J Exp Med 201(2): 233-40; Yen, D., J. Cheung, et al. (2006). “IL-23 is essential for T cell-mediated colitis and promotes inflammation via IL-17 and IL-6.” J Clin Invest 116(5): 1310-6.). Consistent with these findings, an anti-IL23-specific monoclonal antibody blocks development of psoriasis-like inflammation in a murine disease model (Tonel, G., C. Conrad, et al. “Cutting edge: A critical functional role for IL-23 in psoriasis.” J Immunol 185(10): 5688-91).
In humans, a number of observations support the role of the IL-23/Th17 pathway in the pathogenesis of inflammatory diseases. IL-17, the key cytokine produced by Th17 cells, is expressed at elevated levels in a variety of allergic and autoimmune diseases (Barczyk, A., W. Pierzchala, et al. (2003). “Interleukin-17 in sputum correlates with airway hyperresponsiveness to methacholine.” Respir Med 97(6): 726-33; Fujino, S., A. Andoh, et al. (2003). “Increased expression of interleukin 17 in inflammatory bowel disease.” Gut 52(1): 65-70; Lock, C., G. Hermans, et al. (2002). “Gene-microarray analysis of multiple sclerosis lesions yields new targets validated in autoimmune encephalomyelitis.” Nat Med 8(5): 500-8; Krueger, J. G., S. Fretzin, et al. “IL-17A is essential for cell activation and inflammatory gene circuits in subjects with psoriasis.” J Allergy Clin Immunol 130(1): 145-154 e9.). Furthermore, human genetic studies have shown association of polymorphisms in the genes for Th17 cell-surface receptors, IL-23R and CCR6, with susceptibility to IBD, multiple sclerosis (MS), rheumatoid arthritis (RA) and psoriasis (Gazouli, M., I. Pachoula, et al. “NOD2/CARD15, ATG16L1 and IL23R gene polymorphisms and childhood-onset of Crohn's disease.” World J Gastroenterol 16(14): 1753-8., Nunez, C., B. Dema, et al. (2008). “IL23R: a susceptibility locus for celiac disease and multiple sclerosis?” Genes Immun 9(4): 289-93; Bowes, J. and A. Barton “The genetics of psoriatic arthritis: lessons from genome-wide association studies.” Discov Med 10(52): 177-83; Kochi, Y., Y. Okada, et al. “A regulatory variant in CCR6 is associated with rheumatoid arthritis susceptibility.” Nat Genet 42(6): 515-9.).
Ustekinumab (Stelara®), an anti-p40 monoclonal antibody blocking both IL-12 and IL-23, is approved for the treatment of adult patients (18 years or older), with moderate to severe plaque psoriasis, who are candidates for phototherapy or systemic therapy. Currently, monoclonal antibodies specifically targeting only IL-23, to more selectively inhibit the Th17 subset, are also in clinical development for psoriasis (Garber K. (2011). “Psoriasis: from bed to bench and back” Nat Biotech 29, 563-566), further implicating the important role of the IL-23- and RORγt-driven Th17 pathway in this disease. Results from recent phase II clinical studies strongly support this hypothesis, as anti-IL-17 receptor and anti-IL-17 therapeutic antibodies both demonstrated high levels of efficacy in patients with chronic psoriasis (Papp, K. A., “Brodalumab, an anti-interleukin-17-receptor antibody for psoriasis.” N Engl J Med 2012 366(13): 1181-9; Leonardi, C., R. Matheson, et al. “Anti-interleukin-17 monoclonal antibody ixekizumab in chronic plaque psoriasis.” N Engl J Med 366(13): 1190-9.). Anti-IL-17 antibodies have also demonstrated clinically relevant responses in early trials in RA and uveitis (Hueber, W., Patel, D. D., Dryja, T., Wright, A. M., Koroleva, I., Bruin, G., Antoni, C., Draelos, Z., Gold, M. H., Durez, P., Tak, P. P., Gomez-Reino, J. J., Foster, C. S., Kim, R. Y., Samson, C. M., Falk, N. S., Chu, D. S., Callanan, D., Nguyen, Q. D., Rose, K., Haider, A., Di Padova, F. (2010) Effects of AIN457, a fully human antibody to interleukin-17A, on psoriasis, rheumatoid arthritis, and uveitis. Sci Transl Med 2, 5272.).

Methods of Use
The present invention is directed to a method for preventing, treating or ameliorating a RORγt mediated inflammatory syndrome, disorder or disease comprising administering to a subject in need thereof an effective amount of a compound of Formula I or a form, composition or medicament thereof.
Since RORγt is an N-terminal isoform of RORγ, it is recognized that compounds of the present invention which are modulators of RORγt are likely to be modulators of RORγ as well. Therefore the mechanistic description “RORγt modulators” is intended to encompass RORγ modulators as well.
When employed as RORγt modulators, the compounds of the invention may be administered in an effective amount within the dosage range of about 0.5 mg to about 10 g, preferably between about 0.5 mg to about 5 g, in single or divided daily doses. The dosage administered will be affected by factors such as the route of administration, the health, weight and age of the recipient, the frequency of the treatment and the presence of concurrent and unrelated treatments.

Some compounds of the present invention may exist as atropisomers. Atropisomers are stereoisomers resulting from hindered rotation about single bonds where the steric strain barrier to rotation is high enough to allow for the isolation of the conformers. It is to be understood that all such conformers and mixtures thereof are encompassed within the scope of the present invention.
Where the compounds according to this invention have at least one stereo center, they may accordingly exist as enantiomers or diastereomers. It is to be understood that all such isomers and mixtures thereof are encompassed within the scope of the present invention.
Where the processes for the preparation of the compounds according to the invention give rise to mixture of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared in racemic form, or individual enantiomers may be prepared either by enantiospecific synthesis or by resolution. The compounds may, for example, be resolved into their component enantiomers by standard techniques, such as the formation of diastereomeric pairs by salt formation with an optically active acid, such as (−)-di-p-toluoyl-D-tartaric acid and/or (+)-di-p-toluoyl-L-tartaric acid followed by fractional crystallization and regeneration of the free base. The compounds may also be resolved by formation of diastereomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral HPLC column.
During any of the processes for preparation of the compounds of the present invention, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned. This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry , ed. J. F. W. McOmie, Plenum Press, 1973; and T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis , John Wiley & Sons, 1991. The protecting groups may be removed at a convenient subsequent stage using methods known from the art.

General Schemes:
Compounds of Formula I in the present invention can be synthesized in accordance with the general synthetic methods known to those who are skilled in the art. The following reaction schemes are only meant to represent examples of the invention and are in no way meant to be a limit of the invention.
Scheme 1 describes the preparation of 6-bromo or 6-iodoquinolines of the Formula IV by various methods. As illustrated in path 1, hydroxyquinolin-2(1H)-ones II can be prepared by condensation of readily available 6-bromo or 6-iodoanilines with Meldrum's acid and then subsequently heated in the presence of Eaton's reagent or PPA as described by W. T. Gao, et al. ( Synthetic Communications 2010, 40, 732). Condensation with substituted aldehydes in the presence of a Hantzsch ester, such as diethyl 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate, in solvents like ethanol or pyridine can afford substituted 6-halo-4-hydroxyquinolin-2(1H)-ones III wherein R 6 is C (1-4) alkylQ and Q is defined above. Subsequent heating of quinolines III in the presence of phosphorus oxychloride at temperatures between 80-120° C. with or without a solvent, such as acetonitrile, can provide the 6-bromo or 6-iodoquinolines IV wherein R 5 and R 7 are Cl.
