Versuchsvorschrift

0.10 g (0.00027 mol) of N-(6-chloro-2-methylamino-pyrimidin-4-yl)-3-trifluoromethyl-benzenesulfonamide was dissolved in 5 ml of EtOH, treated with 0.27 g (0.004 mol) of methylamine hydrochloride and 1 ml (0.007 mol) of triethylamine and stirred in an autoclave at 145° C. for 17 hours. The entire reaction mixture was partitioned in ethyl acetate/water and extracted. The residue was recrystallized in MeOH. There was obtained 0.055 g (56%) of N-(2,6-bis-methylamino-pyrimidin-4-yl)-3-trifluoromethyl-benzenesulfonamide as white crystals; m.p. 234-235° C.
