Sodium Thiosulfate → HCID 86638699, compound

Participants

Reaction Steps

To a solution of 1.50 g of rel-[(3R,4R)-3-(3-fluorophenyl)-1-(trifluoroacetyl)piperidin-4-yl]methanol in 15 mL of dichloromethane was added 2.29 of Dess-Martin Periodinane at room temperature, followed by stirring for 1.5 hours. To the reaction mixture were added a saturated aqueous sodium thiosulfate solution and a saturated aqueous sodium hydrogen carbonate solution, followed by extraction with chloroform. The organic layer was washed with water and saturated brine in this order, and dried over sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 1.83 g of crude rel-(3R,4R)-3-(3-fluorophenyl)-1-(trifluoroacetyl)piperidine-4-carbaldehyde as an orange oily compound.
