AbstractMethyl 4-chloro-2-(N-methyl-N-phenylsulfamoyl)benzoate(1) was obtained from 2-amino-4-chlorobenzoic acid by three steps which contain diazotization,esterification and oxidation condensation. And the effects of reaction temperature,mass of the catalyst,molar ratio of raw materials on the reation were investigated. The results of experiment showed that compound 1 was obtained with a yield of more than 62.7% under the optimum conditions. The producing process is easy to control with high yield and low cost, and it is suitable for industrial production. The structure of compound 1 was confirmed with 1H NMR, MS, IR, 13C NMR and melting points. |
