실험 절차

A mixture of 5-formamido-3-(2-methylthio-2-methylsulfinylacetyl)-1,2,4-thiadiazole (0.85 g) and sodium periodate (0.2 g) in glacial acetic acid (10 ml) was stirred for 45 minutes at 70° C. The reaction mixture was evaporated and the residue was dissolved in a mixture of ethyl acetate and water. The mixture was adjusted to pH 7 with an aqueous solution of sodium bicarbonate and treated with an aqueous solution of sodium thiosulfate. The organic layer was separated, dried over anhydrous magnesium sulfate and evaporated to dryness. The residue was triturated with a mixture of diethyl ether and petroleum ether to give the title compound (280 mg), mp. 186° to 187° C.
