SYNTHESIS METHOD OF THIADIAZOLYLAMIDE DERIVATIVE

摘要

A synthesis method of 2-[(5-(trifluoromethyl)-1,3,4-thiadiazolyl-2-yl)-oxy]amide derivative (I). The method comprises the following step: in a solvent insoluble with water, 2-sulphinyl-5-trifluoromethyl-thiadiazole (II) and amide (III) reacting under the effect of alkali to obtain 2-[(5-(trifluoromethyl)-1,3,4-thiadiazolyl-2-yl)-oxy]amide. The reaction can also be performed in the presence of a catalyst.
