Process for producing 1-bromo-4-phenylbutane

摘要

A process for producing 1-bromo-4-phenylbutane of the formula (1): which is characterized by the steps of; reacting 4-bromobutyryl halide of the formula (2): where X is a halogen atom, with benzene in the presence of a Lewis acid to give a 4-bromobutyrophenone of the formula (3): and reacting 4-bromobutyrophenone compound of the formula (3) with hydrogen in the presence of a metal catalyst.
