실험 절차

To a solution of 1.5 g of 1-methyl-4-(o-chlorophenyl)-5-methyl-1,2-dihydrothieno[2,3-d]pyrimidin-2-one in 30 ml of chloroform is added dropwise 1.62 g of sulfuryl chloride in 6 ml of chloroform. After stirring the reaction mixture for 2 hours at room temperature, the reaction mixture is neutralized with aqueous ammonia, then extracted with chloroform. The chloroform extracts are washed with water, dried, evaporated under reduced pressure to a residue to give crystals of 1-methyl-4-(o-chlorophenyl)-5-methyl-6-chloro-1,2-dihydrothieno[2,3-d]pyrimidin-2-one, which are recrystallized from ethanol to give 1.252 g of crystals having a melting point of 199.5° - 200.5°C; yield 74.5 %.
