Reaction Steps

A mixture of 14.2 g (0.1 mole) of 2-mercapto-4,6-diamino-pyrimidine, 30.4 g (0.115 mole) of (1,2-dibromo-ethyl)-benzene, 200 ml of dimethyl formamide and 13.8 g (0.1 mole) of potassium carbonate is stirred at 45° C. for 6 hours. The reaction mixture is cooled, the precipitate is filtered, washed with water and dried. Thus 26.0 g of the desired compound are obtained, yield 80%, m.p.: above 300° C.
