Procedure

A solution of 2-(4-bromophenyl)acetic acid (20.0 g, 93.46 mmol, 1.00 equiv) in thionyl chloride (40 mL) was refluxed for 2 h. The resulting mixture was concentrated under vacuum to give 20 g (92%) of 2-(4-bromophenyl)acetyl chloride as a white solid.

Workup

concentrationThe resulting mixture was concentrated under vacuum
