Procedure

7 g of aminoacetic acid ethyl ester chloride, 20.7 g of 2-nitro-5-(2,6-dichloro-4-trifluoromethyl-phenoxy)-benzoic acid chloride and 180 ml of acetonitrile were initially introduced into the reaction vessel. 4 g of sodium hydroxide, dissolved in 10 ml of water, were added dropwise at -10° to -5° C. The reaction mixture was then poured onto water and adjusted to pH 10 and the crystalline product was filtered off. 23 g (95% of theory) of 5-(2,6-dichoro-4-trifluoromethyl-phenoxy)-2-nitro-benzoic acid (ethoxycarbonylmethyl)-amide with a melting point of 146° C. were obtained.
