METHOD FOR PREPARING THIADIAZOLYLAMIDE COMPOUNDS

摘要

Disclosed is a method for preparing thiadiazolylamide compounds. 2-sulfinyl-5-(trifluoromethyl)-1,3,4-thiadiazole (II) and 2-sulfuryl--5- (trifluoromethyl)-1,3,4-thiadiazole (II') are mixed in mass ratio of 99:1-1:99 as mixed raw materials, and then the mixed raw materials and compound (III) are reacted in the solution of solvent and inorganic base at the temperature of -20-25 ℃ to obtain compound (I). The method disclosed by the invention is simple in the preparation of the mixed raw materials, convenient to operate, high in reaction speed and yield, less in 'three wastes', and suitable for industrial production.
