Procedure
Bromine (0.02 mol) was added dropwise to a stirred solution of 4'-chlorohexanophenone (0.02 mol) in dry diethyl ether (20 ml) at 10°-20° over one hour. The ether was then removed in vacuo from the reaction mixture to leave a pale-yellow liquid which on distillation gave 2-bromo-4'-chlorohexanophenone, b.p. 124°-126°/0.04 mm Hg.
