Sodium borohydride → HCID 59278380, compound

Participants

Reaction Steps

To a chilled (0° C.) solution of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid [(S)-1-(2-formyl-pyridin-4-yl)-propyl]-amide (95 mg, 0.24 mmol) in THF (2 mL) and methanol (2 mL) was added sodium borohydride (17.8 mg, 0.47 mmol). The mixture was then warmed to room temperature. After 1.5 hours, the mixture was quenched with water (5 mL) and extracted with EtOAc (20 mL). The organic layer was washed with brine, dried over sodium sulfate, filtered and concentrated. The mixture was purified by silica gel chromatography eluting with a gradient of 0-10% methanol in dichloromethane to afford the title compound as a white solid.
