실험 절차

0.262 g (1.00 mmol) of (2-chloro-5,5-dioxo-6,7-dihydro-5H-5λ6-thieno[3,2-d]pyrimidin-4-yl)propylamine (II) and 0.433 g (2.20 mmol) of 1-(4-chlorophenyl)piperazine are placed in 4.50 mL of dioxane, then heated to 150° C. in the microwave for 0.75 hours. Then the reaction mixture is concentrated by evaporation, the residue is treated with water. It is suction filtered, washed with water, and dried. The product which is not yet clean is purified by chromatography (column: 10 g Chromabond SiOH cartridge, solvent: petroleum ether/ether 1:1). Corresponding fractions are combined and concentrated by evaporation. 0.295 g of product III (70%) is obtained as a powder (m.p. 243° C.-245° C.).
