Reaction Steps
A mixture of methyl 5-docosa-4,7,10,13,16,19-hexaenamido-2-hydroxybenzoate (0.1 g, 0.2 mmol) in 2N NaOH (5 mL) and CH3OH (2.5 mL) was stirred (50° C., 24 h). The mixture was cooled and acidified to pH 1 with 2N aq. HCl, then extracted with EtOAc (3×10 mL). The organic layer was washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by silica chromatography (CH2Cl2-EtOAc, 20:1 to 1:1) to afford 5-docosa-4,7,10,13,16,19-hexaenamido-2-hydroxybenzoic acid as a white solid (90.4 mg, yield: 90%). Mass calculated for C29H37NO4=463.61. found: [M+H]+=464.3.
