Reaction Steps

To a solution of 2-mercapto-3-methylthieno[3,2-d]-pyrimidin-4(3H)-one (1.98 g) and 1N-sodium hydroxide/water (10.5 ml) in ethanol (30 ml) was added 4-(6-chloronicotinoyl)benzyl bromide (3.35 g) and the mixture was stirred at 60° C. fro 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 light-yellow solid (3.194 g).
