Procedure
A mixture of 4-methoxybenzylchlorine and piperazine was treated according to the general preparation 1 to obtain N-(4-methoxybenzyl) piperazine dihydrochloride, yield 75%, mp. 250-252° C. The N1-(4-methoxybenzyl)-N4-phenacyl piperazine dihydrochloride (0.5 g, 1.23 mmol) could be preparated according to the general preparation 2, and then reduced according to the general preparation 3 to obtain 0.38 g of the title compound, yield 77.55%, mp 244-246° C.).
