Procedure

To a room temperature solution of methanesulfonic acid(S)-3-{[1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carbonyl]-amino}-3-(2-methanesulfonyl-pyridin-4-yl)-propyl ester (122 mg, 0.223 mmol) in DMF (2 mL) was added sodium azide (19 mg, 0.29 mmol). After 72 hours, the reaction was quenched with water (20 mL) and extracted with EtOAc (3×20 mL). The combined organic layers were washed with water (20 mL), brine (20 mL), dried over magnesium sulfate, filtered and concentrated. The mixture was passed through a plug of silica gel eluting with a gradient of 0-5% methanol in dichloromethane to afford 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid[(S)-3-azido-1-(2-methanesulfonyl-pyridin-4-yl)-propyl]-amide which was used without further purification.
