| titleOfInvention | A kind of preparation method of 2-amino-5-chloro-N,3-dimethylbenzamide |
| abstract | The invention relates to a preparation method of 2-amino-5-chloro-N,3-dimethylbenzamide. The preparation method comprises the following steps: taking 2-nitro-3-methylbenzoic acid as a starting material, successively undergoing reduction reaction, chlorination reaction, esterification reaction and ammonolysis reaction to obtain 2-amino-5-chloro ‑N,3‑Dimethylbenzamide. The preparation method of the present invention provides a new path for the synthesis of 2-amino-5-chloro-N, 3-dimethylbenzamide, the yield of the whole route can reach more than 80%, and the cost is significantly reduced. The reaction conditions are mild, the amount of three wastes is small, and it is suitable for industrial production. |
