実験手順

123 Grams of succinimide 3,4-dimethoxybenzoate and 137 mg of 6-(1-piperazinylcarbonyl)-3,4-dihydrocarbostyril were dissolved in 2 ml of dimethylformamide and stirred for 24 hours. The water was added to the reaction mixture and extracted with chloroform, the chloroform extract was washed with water and a saturated sodium chloride aqueous solution and dried with anhydrous sodium sulfate. The solvent was removed by distillation and the residue was recrystallized from ethanol-chloroform to obtain 100 mg of 6-[4-(3,4-dimethoxybenzoyl)-1-piperazinylcarbonyl]-3,4-dihydrocarbostyril. Colorless granular crystals. Melting point: 238°-239.5° C.
