Procedure

A mixture of 9.45 g. (21 mmole) 4-{2-[1-(2-chlorobenzyl)-piperazin-4-yl]-ethyl}-benzoyl chloride dihydrochloride, 50 ml. methylene chloride and 3.3 g. (28 mmole) 2-diethylaminoethanol is maintained at reflux temperature for 3 hours, then cooled and mixed with diethyl ether until turbidity appears. A thick precipitate is slowly deposited. This is filtered off with suction, washed with sec.-butanol and dissolved in a hot mixture of sec.-butanol and ethanol. Upon cooling and partial concentration, there are obtained 5.0 g. (35% of theory) of the desired compound in the form of its dihydrochloride; m.p. 220°-221° C.
