Procedure
To a solution of 1.33 g of 1-methyl-4-phenyl-5-methyl-1,2-dihyrothieno[2,3-d] -pyrimidin-2-one in 35 of chloroform is added dropwise 1.62 g of sulfuryl chloride in 6 ml of chloroform. After stirring the reaction mixture for 5 hours at room temperature, the reaction mixture is neutralized with aqueous ammonia and 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-phenyl-5-methyl-6-chloro-1,2-dihydrothieno[2,3-d]pyrimidin-2-one, which are recrystallized from ethanol-ether to give crystals having a melting point of 190° - 191.5°C.
