Reaction Steps

A solution of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid[(S)-1-(2-ethanesulfonyl-pyridin-4-yl)-but-3-enyl]-amide (136 mg, 0.284 mmol) in MeOH (30 mL) was hydrogenated over 10% Pd/C using a continuous flow hydrogenation apparatus (conditions: full H2 mode, flow rate 1 mL/minute, 30° C., 1 atmosphere). The solution was concentrated in vacuo and purified by reversed-phase HPLC using a 20 minute gradient of 5-95% acetonitrile (0.1% TFA) in water (0.1% TFA) (flow rate=25 mL/min). The desired fractions were combined, neutralized with saturated aqueous sodium bicarbonate and extracted with dichloromethane (3×20 mL). The combined organic layers were dried over MgSO4, filtered and concentrated to afford the title compound as an off white solid.
