الإجراء التجريبي

0.314 g (0.001 mol) of 4-amino-N-(6-chloro-2-methylamino-pyrimidin-4-yl)-benzenesulfonamide and 6.6 ml (0.1 mol) of ethylamine were stirred in 15 ml of ethanol in an autoclave at 130° C. for 3 hours. The reaction mixture was freed from solvent, the residue was suspended in 8 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 0.18 g (56%) of 4-amino-N-(6-ethylamino-2-methylamino-pyrimidin-4-yl)-benzenesulfonamide as white crystals; m.p.: 252° C. (dec.).
