700 mg of 3-acetoxy-4-methoxy-benzoic acid were suspended in 6 ml of anhydrous DCM and 24 μl of DMF were added. Then 5.0 ml of a 2 M solution of oxalyl chloride in DCM were added dropwise. The mixture was stirred until the evolution of gas had ceased (about 30 min). The volatiles were removed in vacuo, the residue was dissolved in 10 ml of DCM and evaporated to yield 750 mg of the title compound which was used in the subsequent step without further purification.
