750 ml of SOCl2 were added to 239.5 g (1 mol) of 3-chloro-4-trifluoromethoxybenzamide and the mixture was heated slowly (corresponding to the evolution of gas) to 85° C. The mixture was then fractionally distilled and 189 g of product having a boiling point at 13 mbar of 96° C. and a melting point of 38° to 40° C. were obtained. This corresponds to a yield of 85% of theory.
