Reaction Steps
0.25 g (0.00084 mol) of N-(2-methylamino-6-chloro-pyrimidin-4-yl)-benzenesulfonamide was dissolved in 20 ml of 2M methylamine in THF and stirred in an autoclave at 130° C. for 3 hours. The mixture was freed from solvent, the residue was dissolved in 25 ml of 2N NaOH, filtered and the pH value of the filtrate was adjusted to 6 with 1N HCl. The precipitate was filtered off under suction, dried and chromatographed on silica gel with dichloromethane/methanol 95:5. There was obtained 0.09 g (36%) of N-(2,6-bis-methylamino-pyrimidin-4-yl)-benzenesulfonamide as yellowish crystals; m.p.: >260° C. (dec).
