実験手順
N-Cyclopropyl-6-[4-[(3-chlorophenyl)phenylmethyl]-1-piperazinyl]hexanesulfonamide (1.00 g, 2.04 mmol) prepared in the same manner as in Example 1 was dissolved in methanol (10 ml). 2 M hydrochloric acid (factor =1.004) (1.00 ml) was added thereto, and the solvent was then removed by evaporation in vacuo. Acetone was added to the residue, and the precipitated crystals were collected by filtration. The crystals were recrystallized from ethanol-acetone, to give N-cyclopropyl-6-[4-[(3-chlorophenyl)phenylmethyl]-1-piperazinyl]hexanesulfonamide hydrochloride (0.80 g) as colorless prisms (yield based on N-cyclopropyl-6-[4-[(3-chlorophenyl)phenylmethyl]-1-piperazinyl]hexanesulfonamide: 74.8%).
