0.86 g (6.7 mmol) of ethanesulfonyl chloride was added dropwise with ice cooling to a solution of 1.0 g (6.1 mmol) of 5-amino-2,3,4,5-tetrahydro-1-benzoxepine and 2.5 g (24 mmol) of triethylamine in 20 ml of THF. The mixture was allowed to come to room temperature and was stirred overnight, and the solvent was distilled off in vacuo. After stirring the residue with water, the deposited product was filtered off with suction. 1.1 g of 5-ethylsulfonylamino-2,3,4,5-tetrahydro-1-benzoxepine were obtained, m.p. 109-111° C.
