Reaction Steps

The methyl 5-(2-(4Z,7Z,10Z,13Z,16Z,19Z)-docosa-4,7,10,13,16,19-hexaenamidoacetamido)-2-hydroxybenzoate (0.9 g, 1.7 mmol) was dissolved in THF (15 mL) and 1 N NaOH (8 mL). The reaction was stirred (50° C., 5 h), and then acidified to pH 3 with 2 N HCl. The product was extracted with ethyl acetate, and the combined organic extracts were washed with water, brine and dried over MgSO4. The crude material was purified by silica chromatography (0-5% MeOH/CH2Cl2) to afford 0.40 g of 5-(2-(4Z,7Z,10Z,13Z,16Z,19Z)-docosa-4,7,10,13,16,19-hexaenamidoacetamido)-2-hydroxybenzoic acid as a yellow solid. [M+H]+=521.3. Mass calculated for C31H40N2O5=520.66. found: [M−H]+=519.2.
