Versuchsvorschrift

To a stirring solution of 5-bromo-6-chloro-2-(methylthio)pyrimidine-4-amine (intermediate 1) (52.2 mmol) in 450 ml of DCM, a solution of 12.9 g (57.4 mmol) of m-chloroperbenzoic acid (77%) (Sigma-Aldrich) in 100 ml of DCM was slowly added. The reaction mixture was stirred at room temperature for 1 hour. The formed white precipitate was filtered, washed several times with DCM and dried. 13.96 g of 5-bromo-6-chloro-2-(methylsulfinyl)pyrimidine-4-amine were obtained (98.9%).
