Procedure

To 1.5 g of 2-({[(tert-butoxycarbonyl)amino]sulfonyl}amino)ethyl tert-butoxycarbonylsulfamate in 30 ml of dichloromethane are added 30 ml of a 1/1 trifluoroacetic acid/dichloromethane mixture. After stirring for 4 hours at 20° C., the reaction mixture is concentrated under reduced pressure and taken up 3 times in ether and reevaporated. The white solid is taken up in dichloromethane and filtered under vacuum to give 700 mg of the desired product: 2-[(aminosulfonyl)amino]ethyl sulfamate.
