Reaction Steps

Crude 2-(N-benzyloxycarbonylamino)ethanesulfonyl chloride was dissolved in acetonitrile (10 mL). The resulting solution was cooled on an ice/water bath and a solution 1:1 of 28% NH4OH (5 mL) and acetonitrile (5 mL) was dropped therein. After stirring for 30′, the solvents were evaporated off under vacuum and the crude residue was recrystallised with methanol to give 2-(N-benzyloxycarbonylamino)ethanesulfonamide as white powder (0.51 g; 1.96 mmol).
