A solution of 6.5 g (0.03 mole) of 2,6-dichloro-benzoylisocyanate in 20 ml of toluene was added to 5.4 g (0.03 mole) of 4-trifluoromethoxy-aniline dissolved in 80 ml of toluene at 60° C. The batch was stirred for two hours at 80° C, a part of the solvent was distilled off in vacuo and the product which had precipitated was filtered off. After drying, 10 g (84.5% of theory) of analytically pure N-(4-trifluoromethoxyphenyl)-N'-(2,6-dichlorobenzoyl)-urea of melting point 202° C were obtained.
