Reaction Steps

0.2 g (0.00061 mol) of 4-amino-N-(6-chloro-2-dimethylamino-pyrimidin-4-yl)-benzenesulfonamide were dissolved in 20 ml of ethanol, treated with 4.2 ml (0.061 mol) of ethylamine and stirred in an autoclave at 130° C. for 4 hours. The reaction mixture was freed from solvent, the residue was suspended in 5 ml of ethanol and treated in an ultrasound bath for 15 minutes. The precipitate was filtered off, dissolved in 10 ml of 0.1N NaOH and filtered. The filtrate was adjusted to pH 6 with 0.1N HCl. The precipitate was filtered off under suction, washed with water and dried. There was obtained 0.082 g (40%) of 4-amino-N-(2-dimethylamino-6-ethylamino-pyrimidin-4-yl)-benzenesulfonamide as beige crystals; m.p.: 237-238° C.
