1 ml of hydrogen bromide/glacial acetic acid is added to 65.5 g (0.36 mol) of 4-chlorophenyl isopropyl ketone in 200 ml of chloroform, and 57.5 g (0.36 mol) of bromine are then added dropwise at 30° C. The mixture is subsequently stirred at room temperature for 30 minutes and is then concentrated in vacuo. 86.6 g (92% of theory) of crude 2-bromo-prop-2-yl 4-chlorophenyl ketone are obtained and are further reacted directly.
