Reaction Steps

0.30 g (0.001 mol) of 4-amino-N-(2-amino-6-chloro-pyrimidin-4-yl)-benzenesulfonamide and 11 ml (0.1 mol) of benzylamine were dissolved in 15 ml of ethanol and stirred in an autoclave at 130° C. 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 0.15 g (41%) of 4-amino-N-(2-amino-6-benzylamino-pyrimidin-4-yl)-benzenesulfonamide as beige crystals; m.p.;221° C. (dec.).
