Sodium Thiosulfate → HCID 86708220, compound

Participants

Reaction Steps

To a mixture of 2-(2-ethylsulfanyl-4-trifluoromethylphenyl)-3-methyl-6-trifluoromethylsulfanyl-3H-imidazo[4,5-b]pyridine and chloroform (5 ml), 69% of 3-chloroperbenzoic acid (1.05 g) was added under ice-cooling, and then heated to room, temperature, and stirred for 1.5 hours. Then, saturated aqueous sodium hydrogen carbonate solution and saturated aqueous sodium thiosulfate solution was poured, and extracted with chloroform. The combined organic layer was dried over magnesium sulfate, and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to give 0.20 g of 2-(2-ethylsulfonyl-4-trifluoromethylphenyl)-3-methyl-6-trifluoromethylsulfanyl-3H-imidazo[4,5-b]pyridine (hereinafter, Present Compound 306).
