Procedure
To 10 ml of N,N-dimethylformamide, 835 mg of 3-methylthio-5-chloro-1,2,4-thiadiazole and 520 mg of glycerol formal were dissolved, and added 204 mg of sodium hydride (60% in oil) at about 0° C., followed by stirring at about 0° C. for 20 minutes and at room temperature for 30 minutes. Then, the reaction mixture was added to saturated sodium chloride aqueous solution, and extracted with tert-butylmethylether. After the organic layer was dried by anhyrous sodium salfate, the organic layer was concentrated, and the residue obtaind was subjected to silica gel column chromatography (hexane:ethyl acetate=20:1), followed preparative HPLC to obtain 250 mg of 5-(1,3-dioxolane-4-yl)methoxy-3-methylthio-1,2,4-thiadiazole.
