Reaction Steps

0.1 g (0.000293 mol) of 4-amino-N-(6-chloro-2-isopropylamino-pyrimidin-4-yl)-benzenesulfonamide was dissolved in 20 ml of ethanol, treated with 1.93 ml (0.0293 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 min. 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 0.044 g (43%) of 4-amino-N-(6-ethylamino-2-isopropylamino-pyrimidin-4-yl)-benzenesulfonamide as white crystals; m.p.: 266-267° C.
