2.3 g (18 mmol) of ethanesulfonyl chloride were added dropwise with ice-cooling to a solution of 2.68 g (15 mmol) of 3-fluoro-5-amino-6,7,8,9-tetrahydro-5H-benzocycloheptene and 1.5 g (60 mmol triethylamine in 40 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 precipitated product was filtered off with suction. 2.9 g of 3-fluoro-5-(N-ethylsulfonylamino)-6,7,8,9-tetrahydro-5H-benzocycloheptene were obtained, m.p. 118-121° C.
