참여 물질

반응 단계

A mixture of 20.50 g (0.100 mole) of 5-bromo-6-methyl-2,4(1H, 3H)pyrimidinedione, 26.96 g (0.100 mole of 1-(4-chlorophenyl)-piperazine, 10.35 g (0.110 mole) of potassium fluoride dihydrate and 41.40 g (0.300 mole) of potassium carbonate in 200 ml of dimethylsulfoxide was heated at 80° for 72 hours. The reaction mixture was cooled and poured into 1 l of ice water. The solid was collected, washed with water, and recrystallized from ethanol to give 6.05 g of the product as a dull yellow solid.
