PRODUCTION OF N-(2,6-DICHLOROPHENYL)ANILINE

PURPOSE:The reaction between imidoyl chloride and 2,6-dichlorophenol is followed by conversion of the product into a benzamide, which is hydrolyzed to give the titled compound in high yield. CONSTITUTION:The reaction of imidoyl chloride of formulaI(R is H, alkyl, alkoxy, halogen) with 2,6-dichlorophenol is carried out in no solvent in the presence of an acid combining agent to give an imide ester of formula II and the product is heated in a solvent such as diphenyl ether to effect conversion into a benzamide of formula III. Then, the benzamide is hydrolyzed to give the compound of formula IV. EFFECT:The present process can solve the problem on practical production, namely the treatment of unreacting substance in the conventional process and the defect, namely the high cost of 2,6-dichloroaniline as a starting material.
