Abstract

An illustrative embodiment of the invention substitutes solid, non-carcinogenic bis(methanesulfonoxymethyl) ether for bis-chloromethyl ether in a low temperature reaction of about 0 DEG -5 DEG C. for the production of bis-methylene ether pyridinium quaternary compounds. In this way, the production of important nerve agent antidotes (toxogonin, HI-6 and HGG-12) by a method of synthesis using the reactant bis-mesylmethyl ether, is carried out in appreciably greater safety.
