Abstract
The method for producing the benzyl bromide derivatives of the formula: ##STR1## wherein R.sub.1 represents a C.sub.1 to C.sub.5 alkyl group, which comprises reacting a 2-methylphenylacetic acid derivative of the formula: ##STR2## wherein R.sub.1 represents the same meaning above, with bromine in the presence of an alkali metal salt. In case that R.sup.1 is an ethyl or isopropyl group, the recrystallization of the above reaction product from aliphatic hydrocarbon solution gives the benzyl bromide derivatives efficiently and in high purity.
