実験手順

3.24 g (0.02 mol) of 3,4-dichloroaniline are dissolved in 60 ml of dry toluene, and 3.99 g (0.02 mol) of 2-chloro-4-fluoro-benzoyl isocyanate are added in the absence of moisture. The mixture is stirred for one hour at 80° C. and then cooled to 20°-25° C. The precipitate which separates out is filtered off under suction and dried in vacuo at 100° C. 6.8 g (94% of theory) of 1-(2-chloro-4-fluoro-benzoyl)-3-(3,4-dichlorophenyl)-urea of melting point 208° C. are obtained.
