Reaction Conditions

Reaction Steps

A solution of 1.0 g (4.04 mmol) 5-(3-Chloro-phenyl)-nicotinic acid methyl ester in 60.0 ml Ethanol was treated at room temperature (r. t.) with 304 mg (80.7 mmol) of sodium borohydride. The mixture was stirred over night 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/n-heptane 1:1) gave 261 mg (26%) of [5-(3-Chloro-phenyl)-pyridin-3-yl]-methanol.
