11 g of 5-bromo-2-[4-(methylsulfanyl)phenylamino]pyrimidin-4-ol is suspended in 110 ml of glacial acetic acid. While being cooled with ice water, 4.6 ml of a 30% solution of hydrogen superoxide is added in drops. The mixture is stirred for 18 hours at room temperature and then suctioned off. The filter cake is washed twice with water and once with ethanol and dried at 60° C. in a vacuum. 8.75 g (75.7% of theory) of the product with a melting point of 240° C. (decomposition) is obtained.
