Procedure

To a solution of 2-(1-{[1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carbonyl]-amino}-propyl)-5-methyl-oxazole-4-carboxylic acid methyl ester (95.0 mg, 0.217 mmol) in a mixture of THF/Methanol/water (3 mL, 3:1:1) was added LiOH.H2O (36.5 mg, 0.869 mmol). After 3 hours, the reaction mixture was acidified to pH 3-4 with 2 M aqueous hydrochloric acid and concentrated. The mixture was diluted with ethyl acetate (25 mL) and water (25 mL) and stirred vigorously. After 5 hours, the heterogeneous mixture was filtered and the solid was washed with water (until the pH of the filtrate was 5), ethyl acetate (3×10 mL), and air dried to afford the title compound as a white solid. MS m/z 424.74 (MH+).
