反应详情

To a suspension of 1-[2-(4-chloro-phenyl)-thiazol-5-yl]ethanone (5 g, 21 mmol) in methanol (100 ml) is added sodium borohydride (832 mg, 22 mmol) at room temperature. The reaction mixture is stirred at room temperature for 0.5 hour. The reaction mixture is quenched with 100 ml of an aqueous saturated solution of ammonium chloride, extracted with dichloromethane (2×150 ml). The combined organic extracts are dried over magnesium sulphate, filtered and evaporated to dryness to give 1-[2-(4-chloro-phenyl)-thiazol-5-yl]ethanol (4.88 g).
