Procedure

In a sealed tube, a solution of [4-({[1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carbonyl]-amino}-methyl)-pyridine-2-sulfonyl]-acetic acid ethyl ester (40 mg, 0.08 mmol) in a 7 N solution of ammonia in methanol (345 μL, 2.41 mmol) was warmed at 100° C. After 6 hours, the mixture was cooled to room temperature, and the resulting precipitate collected by filtration. The solid was purified by reversed-phase HPLC (C18 column, flow rate=25 mL/minute) using a 20 minute gradient of 5-95% acetonitrile (0.1% TFA) in water (0.1% TFA). Desired fractions from the column were combined and neutralized with saturated aqueous sodium bicarbonate, concentrated and extracted with a 10% solution of methanol in dichloromethane (3×30 mL). The combined organic layer were dried over magnesium sulfate, filtered and concentrated. The solid was triturated with methanol (3×1 mL), filtered and dried to afford the title compound.
