Abstract
PURPOSE: To prepare the titled compound useful as a raw material of pesticides, dyes, etc., with a simplified process, in high yield, by the partial decarbonylation reaction of 5-chloroisophthaloyl chloride followed by amidation and Hofmann rearrangement reaction.
CONSTITUTION: 5-Chloroisophthaloyl chloride is used as a raw material and is subjected to the partial decarbonylation reaction to obtain 3,5-dichlorobenzoyl chloride, which is amidated with ammonia or ammonia water to obtain 3,5- dichlorobenzamide. The objective 3,5-dichloroaniline is prepared from the 3,5- dichlorobenzamide by reacting with a hypohalous acid alkali metal salt or alkaline earth metal salt, and hydrolyzing the product. The compound used as a raw material can be prepared at an extremely low cost, in high yield, by reacting isophthaloyl chloride with chlorine.
