Production Methods
Public sources do not provide a published industrial synthesis for 1 (4 chlorophenyl) 3 (2,6 dichlorobenzoyl)urea, but its production can be described based on standard benzoylurea chemistry and its chemical structural. It would have been produced by first preparing the 2,6 dichlorobenzoyl chloride intermediate from the corresponding acid, followed by reaction with 4 chloroaniline to form a substituted benzamide. This benzamide is then converted into the final benzoylurea through controlled phosgene type carbamoylation or by using safer phosgene substitutes, yielding the urea linkage characteristic of this insecticide family.
