Versuchsvorschrift

N-Cyclopropyl-6-[4-[(3-chlorophenyl)phenylmethyl]-1-piperazinyl]hexanesulfonamide (253 mg, 0.52 mmol) prepared in the same manner as in Example 1 was dissolved in methanol (15 ml). Maleic acid (138 mg, 1.19 mmol) was added thereto. After dissolving the mixture with heating, the solvent was removed by evaporation in vacuo. Acetone-diethyl ether was added to the residue, and the precipitated crystals were collected by filtration. The crystals were recrystallized from ethyl acetate, to give N-cyclopropyl-6-[4-[(3-chlorophenyl)phenylmethyl]-1-piperazinyl]hexanesulfonamide dimaleate (189 mg) as colorless prisms (yield based on N-cyclopropyl-6-[4-[(3-chlorophenyl)phenylmethyl]-1-piperazinyl)hexanesulfonamide: 50.3%).
