Sodium Bicarbonate → (1-{1-[2,4-Bis(trifluoromethyl)phenyl]ethyl}piperidin-4-yl)methanol

Participants

Reaction Steps

To a solution of (1-{1-[2,4-bis(trifluoromethyl)phenyl]ethenyl}piperidin-4-yl)methanol (12.6 g) in methanol (178 mL) was added sodium borohydride (2.02 g). The reaction mixture was stirred at room temperature for 20 min, saturated aqueous sodium hydrogen carbonate solution was added, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (10.9 g).
