실험 절차

1,3-Cyclopentane dicarboxylic anhydride (2.2 g., 15 mmole) and 4.0 g. (15 mmole) of 1-(4-aminobutyl)-4-(3-chlorophenyl)piperazine were combined in 300 ml. of methylene chloride and stirred for 30 minutes at room temperature. The solvent was replaced with xylene and the mixture was refluxed for 48 hours with water removal via a Dean-Stark trap. The solvent was removed in vacuum and the residue filtered through 75 g. of silica gel with 2% ethanol/chloroform as eluent. The product was concentrated in vacuum and crystallized from 50 ml. of isopropanol with addition of 4N isopropanolic HCl. Recrystallization from ethanol gave 1.6 g. of the title compound as the hydrochloride, quarter hydrate; m.p. 199°-202° C.
