Reaction Steps

0.79 g (0.00234 mol) of 4-amino-N-(2,6-bis-ethylamino-pyrimidin-4-yl)-benzenesulfonamide was dissolved in 150 ml of methanol, treated with 2.0 ml (0.0070 mol) of 3.5N ethanolic hydrochloric acid and stirred at 0° C. for 2 hours. The solution was freed completely from solvent and the residue was recrystallized from ethanol/diethyl ether. There was obtained 0.61 g (70%) of 4-amino-N-(2,6-bis-ethylamino-pyrimidin-4-yl)-benzenesulfonamide hydrochloride as pale beige crystals; m.p. 197-208° C.
