Using 4-(2-naphthyl)piperidine (149 mg, 0.60 mmol) and 2-(3-chloropropyl)isoindoline hydrochloride (209 mg, 0.90 mmol) instead of 4-(3-indolyl)piperidine and 3-dimethylaminopropyl chloride hydrochloride respectively, reaction, extraction, and concentration were carried out in the same procedure as Example 4. The resulting crude product was purified by column chromatography on a silica gel (silica gel NH-DM 1020 produced by Fuji Silysia Chemical Ltd., eluent; chloroform) to afford a free form (119 mg) of the title compound as a colorless viscous oil. After adding hydrochloric acid/methanol to a solution of the free form in methanol, the mixture was concentrated and was then recrystallized from ethanol/ethyl acetate to afford the title compound (110 mg, yield: 41%) as white crystals.
