9.8 g of 5-bromo-2-chloropyrimidin-4-ol is suspended in 200 ml of acetonitrile. After 7.2 g of 4-methylsulfanyl-phenylamine is added, 12 ml of a 4N solution of HCl in dioxane is added in drops while being stirred vigorously. After drop-by-drop addition of 5 ml of water, the mixture is stirred for 3 hours at 78° C. and for 2 days at room temperature. The mixture is cooled in an ice bath and suctioned off. The filter cake is washed twice with acetonitrile and dried. 15.2 g (92.7% of theory) of the product with a melting point of 238° C. (decomposition) is obtained.
