Procedure

3.8 Grams of 3-phenyl-3-cyanopropylmesylate was dissolved in 60 ml of dimethylformamide, then to this solution was added 4.0 g of sodium iodide and stirred at 60° to 70° C. for 30 minutes. Next, 5.8 g of 6-(1-piperazinylcarbonyl)-3,4-dihydrocarbostyril hydrochloride and 5.5 ml of triethylamine were added thereto and heated at 70° to 80° C. for 5 hours. The solvent was removed by evaporation, to the residue thus obtained was added 5%-potassium carbonate aqueous solution, then the mixture was extracted with chloroform. The extract was washed with water, and an aqueous solution saturated with sodium chloride, and dried with magnesium sulfate. After removal of the solvent by evaporation, the residue thus obtained was purified by means of a silica gel column chromatography (eluent: dichloromethane →dichloromethane:methanol=100:5), then the desired product was converted into a hydrochloride, recrystallized from ethanol-water to yield 2.0 g of 6-[4-(3-cyano-3-phenylpropyl)-1-piperazinylcarbonyl]-3,4-dihydrocarbostyril.monohydrochloride. Colorless powdery substance.
