3000 mg (17.791 mmol) of 1-(4-chlorophenyl)propan-1-one are placed in 15 ml dichloromethane and treated with one drop of hydrobromic acid. The mixture is stirred at 35° C., then 2843 mg (17.791 mmol) of bromine are added dropwise so that the reaction solution decolorizes again after each addition. Three hours after the start of the reaction, the mixture is evaporated to dryness. 4490 mg (96% of theory) of the target compound are obtained.
