実験手順
6-[4-(3,4-Dimethoxybenzoyl)-1-piperazinyl]-3,4-dihydrocarbostyril (1.96 g) and 0.25 g of 50% oily sodium hydride were mixed with 60 ml of DMF and stirred at room temperature for 2 hours. Then, to the mixture was added 0.66 g of propargyl chloride and the mixture was stirred at room temperature for 7 hours. The reaction mixture was poured into a 150 ml of saturated saline solution and organic substances were extracted with chloroform. The chloroform layer was washed with water and dehydrated. Chloroform was distilled off and the residue was purified through silica gel column chromatography followed by recrystallization from ethanol to give 0.34 g of 1-(2-propynyl)-6-[4-(3,4-dimethoxybenzoyl)-1-piperazinyl]-3,4-dihydrocarbostyril, m.p. 152°-154° C., pale yellow needles.
