Reaction Steps
2.5 Grams of 6-(4-chlorobutyl)-3,4-dihydrocarbostyril and 1.8 g of sodium iodide were mixed in 80 ml of acetone and stirred at 50° C. for 2 hours. Then to the reaction mixture was added 80 ml of dimethylformamide and the acetone was removed by distillation, and 2.0 g of 4-(4-tolyl)piperazine and 2.0 g of triethylamine were added to the reaction mixture, and stirred at 70°-80° C. for 5 hours. The reaction mixture was concentrated under a reduced pressure to obtain a residue. To the residue was added 50 ml of 5%-sodium hydrogencarbonate aqueous solution and stirred. The precipitates thus formed were collected by filtration, washed with water and dried. Recrystallization from isopropanol-diisopropyl ether, there were obtained 3.1 g of 6-{4-[4-(4-tolyl)- 1-piperazinyl]butyl}-3,4-dihydrocarbostyril in colorless prism-like crystals, having the melting point of 160°-161° C.
