実験手順

A suspension of 0.098 mole of sodium hydride in 30 ml of anhydrous dimethylformamide is heated to 60° C. A solution of 0.098 mole of 4-(2-pyridylmethyl)-2,6-piperazinedione in 15 ml of anhydrous dimethylformamide is added dropwise. When the addition is complete, the mixture is maintained at 60° C. for two hours. The reaction medium is then cooled to 25° C. and a solution of 0.126 mole of 4-(4-fluorophenyl)-1-(3-chloropropyl)piperazine in 10 ml of anhydrous dimethylformamide and 0.1 g of sodium iodide are added rapidly. The mixture is heated to 70° C. until the starting 2,6-piperazinedione has completely disappeared. The reaction medium is concentrated under vacuum. The solid residue is recrystallized in a mixture of iospropyl ether and ethanol (90:10). Pure crystals of 4-(2-pyridylmethyl)-1-{3-[1-(4-fluorophenyl)-4-piperazinyl]propyl}-2,6-piperazinedione are obtained.
