| Zusammenfassung: | The method for producing the benzyl bromide derivatives of the formula: wherein R1 represents a C1 to C5 alkyl group, which comprises reacting a 2-methylphenylacetic acid derivative of the formula: wherein R1 represents the same meaning above, with bromine in the presence of an alkali metal salt. In case that R 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. |
