Procedure
1 g of 2-amino-4-propylamino-6-dimethylamino-pyrimidine 3-oxide of Example 1 is dissolved in 15 ml of ethanol. 0.75 g of N-chlorosuccinimide are added as solution in 35 ml of ethanol, dropwise at room temperature. After 4 hours' stirring the reaction mixture is evaporated to dryness. The oil obtained is taken up in 10 ml of water. The pH is adjusted to 8 by adding sodium hydroxide and the mixture is then extracted with 3×20 ml of butanol. The butanol phase is evaporated to dryness. The residue is recrystallized from 5 ml of acetonitrile. 0.7 g of 2-amino-4-propylamino-5-chloro-6-dimethylaminopyrimidine 3-oxide are obtained.
