Reaction Steps
A mixture of 10.12 g of 4′-chloropropiophenone, 0.1 ml of hydrobromic acid (48% aqueous solution) and 60 ml of acetic acid was cooled to 0° C. under a nitrogen atmosphere. Into the mixture, 3.1 ml of bromine was added dropwise, then, the mixture was allowed to warm to room temperature and stirred for 1 hour. The reaction mixture was concentrated under reduced pressure, to obtain 14.34 g of 2-bromo-4′-chloropropiophenone.
