Abstract:
Disclosed is a method of synthesizing 1,2,4-triazole-3-thione compounds and intermediates thereof. The method includes reacting a hydrazine with glyoxylic acid to form a hydrazono acetic acid intermediate followed by reacting the latter with thiocyanate to obtain the 1,2,4-triazole-3-thione compound. The raw materials involved in the present method are readily available, and the reaction is very specific in terms of regioselectivity, resulting in minimum by-product and high product yield. There are neither specific requirements for special equipment nor special operations such as high vacuum, high temperature, anhydrous and oxygen-free manipulations. The process is simple and generates minimum wastes, suitable for industrial production.

Claim (Index 13):
A compound 8\u2032 of formula (II): wherein: R is selected from a C 1 -C 18  alkyl group, a C 6 -C 18  aryl group, or a C 5 -C 6  heteroaryl group containing oxygen, nitrogen or sulfur, excluding a methyl group, a phenyl and a benzyl group; m is 0 or 1; and HX is selected from a hydrohalic acid, sulfuric acid or phosphoric acid.
