Procedure

160 g of 2-chloro-4-methoxyphenylacetic acid are suspended in 210 ml of toluene, and the suspension is stirred together with 96 ml of thionyl chloride at 80° C. until the evolution of gas has ceased. The volatile components are stripped off, and the residue is distilled. 90 g of an orange oil are obtained (thin-film evaporator 170° C., 0.08 mbar).
