Procedure
0.07 g (0.000179 mol) of 4-(2,6-dibromopyridine-4-sulphonyl)-phenylamine was dissolved in 1.5 ml of dioxane and treated with 3.0 ml of 5.6M dimethylamine in ethanol. The mixture was stirred at room temperature for 2 hrs., the solvents were removed and the residue was chromatographed on silica gel with ethyl acetate/hexane 1:1 and 1:3. There was obtained 0.04 g (63%) of [4-(4-aminobenzenesulphonyl)-6-bromopyridin-2-yl]-dimethylamine as yellowish crystals; m.p.: 170-172° C. (dec.).
