반응 단계
The TFA salt of 1-(2-aminoethyl)-1H-pyrrole-2,5-dione (Aldrich, 280 mg, 1.10 mmol) was taken up in 10 mL of CH3CN along with (4Z,7Z,10Z,13Z,16Z,19Z)-docosa-4,7,10,13,16,19-hexaenoic acid (DHA, 360 mg, 1.1 mmol), HATU (460 mg, 1.2 mmol) and DIEA (0.58 mL). The resulting reaction mixture was stirred at room temperature for 3 h. It was then diluted with EtOAc and washed successively with saturated aqueous NaHCO3 and brine. The organic layer was dried (Na2SO4) and concentrated under reduced pressure. Purification by chromatography (CH2Cl2) afforded 350 mg of (4Z,7Z,10Z,13Z,16Z,19Z)—N-(2-(2,5-dioxo-2H-pyrrol-1(5H)-yl)ethyl)docosa-4,7,10,13,16,19-hexaenamide (70% yield).
