Reaction Steps

68.9 g of bromine are added dropwise to a solution of 73.1 g of 3-fluoro-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-one in 700 ml of ether under ice-cooling during 1 hour. After the mixture is stirred for 1 hour, the reaction mixture is poured into water and the mixture is extracted with ether. The ether layer is washed, dried and evaporated to remove the solvent to obtain 106.8 g of 3-fluoro-6-bromo-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-one as an oil.
