The present invention provides kinase inhibitors of Formula I: wherein W represents inter alia imidazol, oxazol, pyrazol, thiazol as triazol, which are substituted by phenyl or thienyl. The disclosed compounds inhibit p-38 kinase and are useful in the treatment of metastasis or rheumatoid arthritis.

Herein we report investigations into the p38 alpha MAP kinase activity of trisubstituted imidazoles that led to the identification of compounds possessing highly potent in vivo activity. The SAR of a novel series of imidazopyridines is demonstrated as well, resulting in compounds possessing cellular potency and enhanced in vivo activity in the rat collagen-induced arthritis model of chronic inflammation.

This article describes chemistry that was developed to give access to multigram quantities of imidazole 479754 and several related analogues for Eli Lilly's p38 MAPK program targeting therapies to address inflammation. The molecules of interest have an isopropyl sulfonyl group present on the 2-aminobenzimidazole heterocycyle that was found to be labile when heated in polar solvents and/or exposed to high or low pH. Due to this instability issue, the syntheses of the target molecules required optimizing Sonogashira reaction conditions, employing a buffered oxidative method to produce alpha-diones, developing buffered reaction conditions to generate imidazoles, and developing final recrystallization conditions.
