Procedure

To 4 ml of N,N-dimethylformamide, 0.334 g of 5-chloro-3-methylthio-1,2,4-thiadiazole and 0.196 g of 2-furanmethanol were dissolved, and added 0.084 g of sodium hydride (60% in oil) at about 0° C., followed by stirring at about 0° C. for 0.5 hours and at room temperature for 4 hours. Then, the reaction mixture was added to saturated sodium chloride aqueous solution, and extracted with tert-butylmethylether. The organic layer was concentrated, and the residue obtaind was subjected to silica gel column chromatography to obtain 0.25 g of 5-(2-furyl)methoxy-3-methylthio-1,2,4-thiadiazole.
