A stirred suspension of 1.0 g of 3-methoxy-4-nitrobenzoic acid and 1.40 ml of thionyl chloride is heated to reflux for 2 hours. The mixture is cooled to room temperature, 2 ml of iso-octane added and the mixture evaporated in vacuo to a solid residue. The residue is washed with iso-octane (2×2 ml), dried in vacuo to give 1.08 g of cream colored solid.
