Trifluoroacetic acid → HCID 71293218, compound

Participants

Reaction Steps

The resulting tert-butyl 2-((3R,4R)-3,4-bis((9Z,12Z)-octadec-9,12-dienyloxy)pyrrolidin-1-yl)-2-oxoethylcarbamate was dissolved in dichloromethane (2 mL), and stirred at room temperature for 1.5 hours after adding trifluoroacetic acid (0.256 mL, 3.33 mmol). The aqueous layer was extracted with chloroform after adding a saturated sodium bicarbonate aqueous solution to the reaction mixture. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure after filtration. The resulting residue was purified by silica gel column chromatography (chloroform/methanol=100/0 to 85/15) to give compound 61 (60.5 mg, 55.3%).
