Procedure

A solution of (5S,6R,7E,9E,11Z,13E,15S)-16-(4-fluorophenoxy)-5,6,15-trihydroxy-3-oxa-7,9,11,13-hexadecatetraenoic acid, methyl ester, (25 mg, 59 nMol) in methanol (6 mL) was treated with 1 N NaOH (aq) (25 μL, 25 μmol) solution and shaken and allowed to stand. Upon completion, the reaction was treated with saturated potassium monophosphate. Purification by chromatography on an HP20 column eluted with an aqueous methanol gradient gave 10 mg of (5S,6R,7E,9E,11Z, 13E,15S)-16-(4-fluorophenoxy)-5,6,15-trihydroxy-3-oxa-7,9,11,13-hexadecatetraenoic acid; 1H NMR (CD3OD) δ 3.6 (m, 3H), 3.88 (m, 4H), 4.18 (m, 1H), 4.52 (m, 1H), 5.84 (m, 2H), 6.03 (m, 2H), 6.34 (m, 2H), 6.74 (m, 1H), 6.95 (m, 5H) ppm.
