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 ml) in ethanol (30 ml) was added 4-(4-acetoxybenzoyl)benzyl bromide (3.95 g) and the mixture was stirred at 60° C. 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 (3.87 g).
