Sodium Thiosulfate → HCID 90282003, compound

Participants

Reaction Steps

To a solution of 2-[4-(benzyloxy)-2-chlorophenyl]ethanol (1.50 g) in dichloromethane (30.0 mL) was added 1,1,1-triacetoxy-1,1-dihydro-1,2-benziodoxol-3(1H)-one (2.70 g) under ice-cooling, followed by stirring at room temperature for 1 hour. To the reaction mixture was added a 1 M aqueous sodium thiosulfate solution, followed by extraction with chloroform. The organic layer was washed with a saturated aqueous sodium hydrogen carbonate solution and a saturated aqueous sodium chloride solution, then dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain [4-(benzyloxy)-2-chlorophenyl]acetaldehyde (1.01 g).
