5-(2-Chloro-6-fluoro-4-trifluoromethylphenoxy)-2-nitrobenzoic acid (2.5 g) was heated under reflux for 5 hours with thionyl chloride (40 ml). The solution was evaporated under reduced pressure and the yellow oil remaining was taken up in toluene (100 ml). The solution was divided into four portions. Each portion was separately evaporated to give 5-(2-chloro-6-fluoro-4-trifluoromethylphenoxy)-2-nitrobenzoyl chloride as an oil. Three portions were used to prepare esters as follows:
