The 4-(2-propenyloxy)benzoic acid, 5 g (0.028 mol), was refluxed with thionyl chloride (37 mL, 0.51 mol) and several drops of pyridine for 8 hours. The excess thionyl chloride was removed in vacuo leaving 4-(2-propenyloxy)benzoyl chloride as a yellow liquid at 25° C. This acid chloride was used without further purification.
