实验过程

(S)-methyl 2-((5Z,8Z,11Z,14Z,17Z)-eicosa-5,8,11,14,17-pentaenamido)-6-(nicotinamido)hexanoate (140 mg, 0.225 mmol) was taken up in 2 mL of THF along with an aqueous solution of NaOH (35 mg in 2 mL of H2O). The resulting reaction mixture was stirred at room temperature for 2 h. It was then acidified to pH 4 with 2 N HCl and then extracted with EtOAc. The combined organic layers were dried (Na2SO4) and concentrated under reduced pressure to afford 31 mg of (S)-2-((5Z,8Z,11Z,14Z,17Z)-eicosa-5,8,11,14,17-pentaenamido)-6-(nicotinamido)hexanoic acid. MS calculated for C34H47N3O4: 561.36. found: [M+H]+ 562. MS calculated for C32H45N3O4: 535.34. found: [M+H]+ 536.
