Participants

Reaction Steps

In 5.0 ml of methylene chloride was dissolved 0.20 g (0.99 mmol) of 4-methyl-5-phenylthiomethyl-1,2,3-thiadiazole. Then, 0.40 g (2.3 mmol) of m-chloroperbenzoic acid was added to the solution obtained above, and was stirred for 20 hours at room temperature. Then, an aqueous solution of sodium hydrogen sulfite was added to the reaction mixture to stop the reaction, the objective product was extracted with ethyl acetate, the organic layer was washed with a saturated aqueous solution of sodium hydrogen carbonate, the solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography using 2:1 mixture of n-hexane and ethyl acetate. Thus, 0.23 g of the objective compound was obtained.
