Procedure

A 20% aqueous methanolic solution of the salt is prepared by slurrying 5-(2-chloro-4-trifluoromethylphenoxy)-2-nitrobenzoic acid (22.2 g, 90% pure) in water (50 g) and adding a 40% solution of benzyltrimethylammonium methoxide (27 g) in methanol to pH 8. Additional water (0.8 g) is then added to give the desired concentration.
