- Synthetic method of 4-chloro-2-(N-methyl-N-phenyl sulfamoyl) methyl benzoate
-
The invention provides a synthetic method of 4-chloro-2-(N-methyl-N-phenyl sulfamoyl) methyl benzoate. The technical scheme is that 4-chloro-2-aminobenzoic acid is taken as a raw material and has an esterification reaction, a product is subjected to diazotization and the Sandmeyer reaction, methyl 4-chloro-2-(chlorosulfonyl)benzoate is prepared and subjected to condensation with N-methylaniline, and 4-chloro-2-(N-methyl-N-phenyl sulfamoyl) methyl benzoate is obtained. The synthetic method has the advantages of conciseness, high efficiency, mild conditions, no need of purification of an intermediate and simple operation, the total yield of three steps of reactions is as high as 65%, and the method is quite suitable for industrial production.
