반응 단계
The HCl salt of (E)-methyl 4-(2-aminoethylamino)-4-oxobut-2-enoate (0.735 mmol) was taken up in 40 mL of CH3CN along with (5Z,8Z,11Z,14Z,17Z)-eicosa-5,8,11,14,17-pentaenoic acid (EPA, 222 mg, 0.735 mmol), HATU (307 mg, 0.81 mmol) and DIEA (380 μL). The resulting reaction mixture was stirred at room temperature for 2 h and diluted with EtOAc. The organic layer was washed with saturated aqueous NaHCO3, brine, dried (Na2SO4) and concentrated under reduced pressure. Purification by chromatography (95% CH2Cl2, 5% MeOH) afforded 300 mg of (E)-methyl 4-(2-(5Z,8Z,11Z,14Z,17Z)-eicosa-5,8,11,14,17-pentaenamidoethylamino)-4-oxobut-2-enoate (89% yield). MS (EI) calcd for C27H40N2O4: 456.3. found: 457 (M+1).
