Versuchsvorschrift

To a solution of 3,5-dimethyl-2-mercaptothieno[2,3-d]pyrimidin-4(3H)-one (1.06 g) and sodium hydroxide (205 mg) in 50% methanol (16 ml)-DMF (4 ml) was added 4-(4-chlorobenzoyl)benzyl bromide (1.69 g) and the mixture was stirred at room temperature for 1 hour. This reaction mixture was poured in water and the resulting crystals were collected by filtration, rinsed with water, and recrystallized from ethyl acetate to provide the title compound as colorless solid (878 mg).
