To a mixture of 2,6-dimethylbenzoic acid (3 g; 0.02 mol) in toluene (50 ml) was added thionyl chloride (3.6 ml; 0.05 mol). The mixture thus obtained was refluxed for 2 hours. The solvent and the excess thionyl chloride were then evaporated off under reduced pressure. The residue thus obtained was taken up in toluene (50 ml) three times and evaporated under reduced pressure. The product thus obtained (3.6 g) was used without further purification.
