反应详情

Sodium borohydride (405 mg) was added to a solution of ethyl 6-methoxy-5-(trifluoromethyl)pyridine-2-carboxylate (670 mg, described in WO 2005058830) in methanol (20 mL) under ice-cooling, and the mixture was stirred at room temperature for two hours. The reaction solution was poured into water, followed by extraction with chloroform. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and filtered, after which the filtrate was concentrated under reduced pressure to give [6-methoxy-5-(trifluoromethyl)pyridin-2-yl]methanol (540 mg).
