Procedure
To a stirred solution of 4-bromocinnamic acid (16 g) in methanol (150 mL), thionyl chloride (30 mL) was added at 0° C. The reaction mixture was warmed to room temperature and refluxed for 3 hours. After cooling to room temperature, the solvents were evaporated to dryness. The crude compound obtained was used as such for the next step.
