摘要： The present invention relates to a production method of 4′-bromomethyl-2-cyanobiphenyl, which includes reacting 4′-methyl-2-cyanobiphenyl with bromine in the presence of a radical initiator and an oxidant. According to the present invention, since bromine can be regenerated by reacting hydrogen bromide, which is by-produced with the progress of bromination, with an oxidant, inhibition of bromination by hydrogen bromide, coloring by bromine and the like can be prevented. Thus, 4′-bromomethyl-2-cyanobiphenyl useful as a starting material of pharmaceutical products can be produced industrially beneficially.
