Procedure
A solution of 5-({[1-(4-fluoro-phenyl)-1H-indazole-4-carbonyl]-amino}-methyl)-pyridine-2-carboxylic acid ethyl ester (Example 5) (60 mg, 0.1 mmol) in a 7 N solution of ammonia in methanol (0.65 mL, 4.6 mmol) was stirred at 100° C. in a sealed tube for 16 hours. The mixture was cooled to room temperature and filtered. The solid was washed with MeOH (3×3 mL) and dried. The solid was then triturated with ethyl acetate (2 mL), sonicated, filtered and air dried to afford the title compound.
