Procedure

A solution of 3.48 g (0.01 mol) of the 1-(6-ethoxycarbonylhexyl)-4-(o-methoxyphenyl)piperazine in 50 ml of a mixture of ethyl acetate and ethanol (vol. ratio=50:1) was stirred with 1.16 g (0.01 mol) of fumaric acid at 60° C. for 30 minutes. The mixture was left to stand overnight under cooling to give 3.71 g of 1-(6-ethoxycarbonylhexyl)-4-(o-methoxyphenyl)piperazine fumarate. The fumarate was recrystallized from a mixture of ethyl acetate and ethanol (vol. ratio=50:1) to give an analytically pure fumarate having a melting point of 101°-102° C.
