Procedure

0.30 g (0.00077 mol) of N-[4-(6-methylamino-2-pyrrolidin-1-yl-pyrimidin-4-ylsulfamoyl)-phenyl]-acetamide was boiled at reflux in 30 ml of 1N aqueous sodium hydroxide for 3 hours. The mixture was cooled and extracted with ethyl acetate. Crystals then separated from the aqueous phase and, after suction filtration, were chromatographed over silica gel with ethyl acetate/ethanol 9:1 as the eluent. There was obtained 0.082 g (30%) of 4-amino-N-(6-methylamino-2-pyrrolidin-1-yl-pyrimidin-4-yl)-benzenesulfonamide as beige crystals; m.p. 299-301° C.
