Procedure

The resulting 3-((3R,4R)-3,4-bis((9Z,12Z)-octadec-9,12-dienyloxy)pyrrolidin-1-yl)propanoic acid (64 mg, 0.095 mmol) was dissolved in chloroform (2 mL), and stirred overnight at room temperature after adding O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU; Aldrich; 72 mg, 0.190 mmol), diisopropylethylamine (0.083 mL, 0.476 mmol), and a 2 mol/L ammonia methanol solution (0.238 mL, 0.476 mmol). The aqueous layer was extracted with ethyl acetate after adding a saturated sodium bicarbonate aqueous solution to the reaction mixture. The organic layer was washed with water and 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 90/10) to give compound 57 (46.1 mg, 72.1%).
