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 (0.130 g, 0.307 mmol) in DMF (3 mL) was added HATU (0.140 g, 0.368 mmol). After 10 minutes, DIPEA (215 μL, 1.22 mmol) and Gly-OMe.HCl (46.2 mg, 0.368 mmol) was added. After 18 hours, the mixture was concentrated in vacuo. The residue was dissolved in ethyl acetate (30 mL) and washed with 2 N sodium hydroxide (3×10 mL), saturated aqueous ammonium chloride (2×10 mL), saturated aqueous sodium bicarbonate (10 mL) and brine (10 mL). The organic layer was dried over MgSO4, filtered and concentrated. The resulting residue was purified by silica gel chromatography eluting with a gradient of 0-4% methanol in ethyl acetate to afford the title compound. MS m/z 495.71 (MH+).
