2-%284-aminophenyl%29-6-methylbenzothiazole-7-sulfonic acid is 2- (4-aminophenyl) -6-methylbenzothiazole-7-sulfonic acid, and its synthesis method is as follows:
The starting material can be selected from 4-aminobenzoic acid and o-methylthiophenol, etc.
First, 4-aminobenzoic acid is reacted with appropriate reagents to activate its carboxyl group, such as with dichlorosulfoxide to convert to acid chloride. Subsequently, the acid chloride undergoes a nucleophilic substitution reaction with o-methylthiophenol in the presence of a suitable base (such as triethylamine, etc.) to form a sulfur-containing intermediate.
Next, the intermediate undergoes a cyclization reaction under appropriate conditions to construct a benzothiazole ring. The cyclization process may require heating as well as specific catalysts, such as certain Lewis acids, etc., to promote intramolecular cyclization to produce 2- (4-aminophenyl) -6-methylbenzothiazole.
Finally, a sulfonation reaction is performed on the resulting benzothiazole product to introduce a 7-sulfonic acid group. The sulfonation reaction can usually be carried out using sulfonating reagents such as concentrated sulfuric acid or fuming sulfuric acid and reacted at an appropriate temperature. After the reaction is completed, a series of post-processing operations such as neutralization, extraction, recrystallization, etc. are performed to obtain a pure 2- (4-aminophenyl) -6-methylbenzothiazole-7-sulfonic acid product. < Br >
