실험 절차

To a room temperature solution of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid [(S)-1-(1H-pyrazol-3-yl)-propyl]-amide (0.040 g, 0.11 mmol) in THF was added 60% sodium hydride (9 mg, 0.2 mmol) in mineral oil. After 20 minutes, methansulfonyl chloride (25 mg, 0.22 mmol) was added. After 3 hours, the reaction was quenched with saturated aqueous ammonium chloride and the mixture was extracted with EtOAc. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography (the column was equilibrated with dichloromethane-Et3N) eluting with 5% methanol in dichloromethane. Material from the column was crystallized in ether to afford the title compound.
