0.62 g (0.00175 mol) of N-[4-(6-chloro-2-pyrrolidin-1-yl-pyrimidin-4-ylsulfamoyl)-phenyl]-acetamide was dissolved in 20 ml of ethanol, treated with 1.36 g (0.0201 mol) of methylamine hydrochloride and 5.3 ml (0.038 mol) of triethylamine and stirred in an autoclave at 140° C. for 17 hours. The mixture was freed completely from solvent, the residue was partitioned in ethyl acetate/water and filtered off under suction. There was obtained 0.30 g (44%) of N-[4-(6-methylamino-2-pyrrolidin-1-yl-pyrimidin-4-ylsulfamoyl)-phenyl]-acetamide as beige crystals; m.p. 271-274° C.
