Sodium periodate → HCID 59278166, compound

Participants

Reaction Steps

To a solution of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid [(S)-1-(2-methylsulfanyl-pyridin-4-yl)-propyl]amide (0.10 mg, 0.24 mmol) in MeOH (5 mL) was added an aqueous solution of sodium periodate (51 mg, 0.24 mmol). After 1.5 hours, a solid precipitated and additional MeOH (3 mL) was added. After 5 days, mixture was concentrated and partitioned between water (5 mL) and EtOAc (50 mL). The organic phase was separated and the aqueous layer was extracted with EtOAc (20 mL). The combined organic layers were washed with brine, dried over sodium sulfate, and concentrated. The residue was purified by reversed-phase HPLC (Sunfire PrepC18 OBD 5 mM 30×150 mm column) eluting with a gradient of 15-75% acetonitrile in water (0.1% TFA). The fractions from the column were concentrated to remove acetonitrile, made basic with saturated aqueous sodium bicarbonate and extracted with EtOAc. The organic phase was washed with brine, dried over sodium sulfate and concentrated to afford the title compound as a white solid.
