Reaction Steps

A solution of 680 mg of N-acetyl-3-(3',4'-dimethoxyphenyl)-piperidine in 10 ml of tetrahydrofouran was slowly added with stirring at 20° C to 200 mg of lithium aluminum hydride in 10 ml of tetrahydrofuran and the mixture was stirred for an hour and then cooled to 5° C. 10 ml of ethyl acetate were slowly added thereto and the mixture was poured into water and filtered. The aqueous phase was recovered by decanting and was extracted again with ethyl acetate. The combined organic phases were washed with water, dried and evaporated to dryness to obtain 600 mg of N-ethyl-3-(3',4'-dimethoxyphenyl)-piperidine melting at about 50° C.
