実験手順
100 g maleic acid anhydride are dissolved in 1 liter dichloromethane and to this solution are added drop-wise 198 g of the 4-aminobenzenesulfonylazide (approximately 1 mol) prepared according to (3), dissolved in 400 ml dichloromethane. The reaction mixture is left standing for 2 hours at room temperature. The solution is then concentrated in a rotary evaporator to about 200 ml. The light brown product obtained is cooled, filtered, washed with a small amount of dichloromethane and finally dried.
