Reaction Steps

To a suspension of 1-[2-(3,4-dimethoxyphenyl)ethyl]-4-(3-phenylpropyl)piperazine dihydrochloride (1.06 g, 2.40 mmol) in THF (5 mL) is added a solution of sodium hydroxide (1N, 6 mL). To the resulting solution is added ethyl acetate and brine. The organic layer is separated, filtered through silica gel, dried over anhydrous sodium sulfate, concentrated, and dried to give 0.829 g of 1-[2-(3,4-dimethoxyphenyl)ethyl]-4-(3-phenylpropyl)piperazine as a light brown solid.
