反応手順

A solution of 335 mg (1.17 mmol) 5-(4-Trifluoromethyl-phenyl)-nicotinic acid methyl ester in 10.0 ml ethanol was treated at room temperature (r. t.) with 44 mg (1.17 mmol) of sodium borohydride. The mixture stirred two days at 50° C. Then it was poured on ice and extracted tree times with ethyl acetate. The combined organic phases were washed with water, dried (sodium sulphate) and evaporated. Chromatography on silica (eluent: ethyl acetate/methanol 5:1) gave 195 mg (64%) of [5-(4-Trifluoromethyl-phenyl)-pyridin-3-yl]-methanol.
