実験手順
303 mg of sodium borohydride was added little by little to a solution containing 1.46 g of 2-methoxy-3-(2-thienylcarbonyl)pyridine and 10 ml of ethanol under ice-cooling. After stirring at room temperature for 2 hours, water was slowly added thereto and the mixture was extracted with ethyl acetate. The organic phase was washed with brine and the solvent was removed, to give 1.47 g of the target compound.
