Reaction Steps

0.50 g (0.00167 mol) of 4-amino-N-(2-amino-6-chloro-pyrimidin-4-yl)-benzenesufonamide and 11 ml (0.167 mol) of ethylamine were dissolved in 20 ml of ethanol 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 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
