Reaction Steps

Bromine (1.29 mL, 25.1 mmol) was added dropwise at 15-20° C. to a solution of 4-bromoacetophenone (5 g, 25.1 mmol) in DCM (40 mL) and the mixture was stirred at this temperature until the bromine colour was discharged. The mixture was diluted with water and the organic phase was separated. This was dried over sodium sulfate and concentrated to afford 2-bromo-1-(4-bromo-phenyl)-ethanone (6 g, 86%).
