Versuchsvorschrift

To 1 mole of m-chloropropiophenone heated to 85±5° C., bromine was added dropwise under stirring. The reaction temperature was kept at 85±5° C. during and after the addition of bromine, and the reaction was carried on for 2 hours. Then m-chloro-α-bromopropiophenone (compound of formula (II)) was obtained.
