Triacetoxyperiodinane → 1-(2-Bromothiazol-5-yl)propan-1-one

Participants

Reaction Steps

To a solution of 1-(2-bromo-thiazol-5-yl)-propan-1-ol (180 mg, 0.79 mmol) in dichloromethane (10 mL) was added Dess-Martin periodinane (DMP) (330 mg, 0.79 mmol). The reaction was stirred for 2 hours, then diluted with dichloromethane (50 mL), washed with saturated aqueous sodium bicarbonate solution (50 mL) and brine (50 mL), dried over sodium sulfate, filtered and concentrated. The compound was purified by silica gel chromatography eluting with a gradient of 0-100% ethyl acetate in hexanes to afford 1-(2-bromo-thiazol-5-yl)-propan-1-one.
