Preparation: 2, 6-dichlorobenzonitrile reacts with H₂O in the present of sulfuric acid as catalyst. Then the compound reacts with phosgene to produce 2,6-Difluorobenzoyl isocyanate. Finally, it reacts with 4-(3-chloro-5-trifluoromethylpyridine-2-oxygen)-3, 5-dichloroaniline, then Chlorfluazuron is got.
