- Method for preparing polysoproxil intermediate
-
The method comprises the following steps: (1). A hydrogen chloride salt of 2 - chlorine -6 - methylaniline compound 1 is prepared by taking 2 - chlorine -6 - methylaniline compound 1 as a raw material in a suitable solvent, and then subjected to diazotization reaction with a nitration reagent aqueous solution to obtain the diazonium salt 2 - chloro -6 - methylaniline. The iodine-containing reagent is reacted with an iodo reagent to obtain 3 -chloro -2 -iodotoluene compound 2. (2), the compound 2 is reacted with the reactant cyanide to give 2 -chloro -6 -iodo-benzonitrile compound 3. (3), the compound 3 undergoes a hydrolysis reaction to obtain 2 - chloro -6 - methyl benzoic acid compound 4, and the reaction equation is as follows. The method has the advantages of cheap and easily available raw materials, high reaction conversion rate, simplicity and rapidness, mild and controllable reaction conditions, mild reaction conditions, high yield of the obtained product, easy separation and purification, high purity and easy industrial mass production.
