Sodium Thiosulfate → HCID 68663351, compound

Participants

Reaction Steps

To a solution of 2-(2,3-dihydro-1-benzofuran-5-yl)-5-(methylthio)-1,3,4-oxadiazole (0.50 g, 2.13 mmol) in acetonitrile (10 mL) was added m-chloroperbenzoic acid (70%, 1.51 g, 6.40 mmol) at 0° C., and the obtained mixture was stirred at room temperature for 2 days. A saturated aqueous sodium thiosulfate solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=2/1) to give the title compound (0.44 g, yield 78%) as colorless crystals.
