Reaction Steps
(Z)-5-[2,3-Dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2-oxo-1H-indol-4-yl]-4-pentynoic acid (100 mg, 3 mmol) (from Example 10 above) was dissolved in tetrahydrofuran (1 mL), and 1N sodium hydroxide (3 mL) was added. The resulting product, (Z)-5-[2,3-dihydro-3-[(3-methoxy-1H-pyrrol-2-yl)methylene]-2-oxo-1H-indol-4-yl]-4-pentynoic acid sodium salt, was purified via reverse-phase HPLC (acetonitrile-water over 15 minutes).
