A mixture of 2-acetoxy-5-ethyl-4-methylbenzoic acid (11.10 g) and thionyl chloride (20 ml) in dry benzene (100 ml) was heated under reflux for 6 hours, cooled and solvents removed in vacuo. The crude 2-acetoxy-5-ethyl-4-methylbenzoyl chloride was obtained as a liquid which was used as rapidly as possible in the next stage of the synthesis without further purification.
