Sodium Thiosulfate → HCID 178520051, compound

Participants

Reaction Steps

Cyclopropyl(1H-pyrazolo[3,4-b]pyridin-3-yl)methanol (200 mg, 1.06 mmol) was taken up in DCM (8 mL). Dess-Martin (0.448 g, 1.06 mmol) was added to this solution, which was stirred at room temperature for 10 minutes. A solution of 10% sodium thiosulfate in saturated aqueous bicarbonate was added and resulted in a biphasic solution, which was vigorously stirred for 30 minutes. The organic layers were extracted with DCM (3×10 mL), dried over sodium sulfate and concentrated. Chromatography (EtOAc) afforded cyclopropyl(1H-pyrazolo[3,4-b]pyridin-3-yl)methanone (100 mg, 50.5%) as an oil, which crystallized upon standing.
