Participants

Reaction Steps

0.62 g of 1-[2-(4-Fluorophenyl)-2-(4-t-butoxycarbonylpiperazino)ethyl]-4-(4-naphthalen-1-yl-butyl)piperazine was dissolved in a mixture of 3 ml of ethyl acetate and 3 ml of methanol, and 4 ml of 4M hydrogen chloride/ethyl acetate solution was added, followed by stirring at room temperature for 6 hours. The precipitated crystals were collected by filtration, and the crystals were washed with ethyl acetate to give 0.42 g of 1-[2-(4-fluorophenyl)-2-piperazinoethyl]-4-(4-naphthalen-1-yl-butyl)piperazine tetrahydrochloride as an oil.
