실험 절차
0.16 g (0.00041 mol) of 4-(2,6-dibromopyridine-4-sulphonyl)-phenylamine was dissolved in 6 ml of dioxane and treated with 0.52 ml of 3-dimethylamino-1propylamine. The mixture was stirred at 60° C. for 24 hrs., the solvent was removed and the residue was chromatographed on silica gel firstly with 5% methanol in dichloromethane and then with 10% methanol in dichloromethane. The product-containing fractions were freed from solvent, the residue was dissolved in 1N HCl, filtered and the filtrate was adjusted to pH 9 with 1N NaOH. The precipitate which thereby resulted was filtered off under suction and dried in a high vacuum. There was obtained 0.072 g (43%) of N-[4-(4-aminobenzenesulphonyl)-6-bromopyridin-2-yl]-N',N'-dimethylpropane-1,3-diamine as pink coloured crystals; m.p.: >250° C. (dec.).
