To a solution of 4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-[methyl(phenyl)amino]-3H-imidazo[4,5-c]pyridine-6-carbonitrile (Example 3.174 step 2, 160 mg, 0.339 mmol) in methanol (2 mL) in a sealable tube was added 30% sodium hydroxide solution (4 mL). The tube was sealed and heated to 80° C. for 14 hours. The reaction mixture was cooled to room temperature and neutralized with the addition of 1.5 M HCl solution. The solution was extracted with ethyl acetate (4×25 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by preparative HPLC (Kromasil C18, water/acetonitrile+0.1% TFA modifier) to afford 4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-[methyl(phenyl)amino]-3H-imidazo[4,5-c]pyridine-6-carboxylic acid (TFA salt).
