Reaction Steps

To a flask was added compound 64 (20 mg) and 1 M aqueous NaOH (1 mL). The mixture was heated to 100° C. for 3 hrs. After being neutralized with acetic acid, the solution was concentrated and the residule was purified by reverse phase HPLC to afford 33 mg (71%) of the desired product. 1H NMR (300 MHz, CD3OD) δ 8.85 (m, 1 H), 8.60 (s, 1 H), 8.35 (d, 1 H), 8.10 (d, 1 H), 7.35 (m, 2 H), 4.40 (m, 1 H), 3.50 (m, 2 H), 3.30 (m, 2 H), 2.40 (m, 2 H), 1.95 (m, 2 H). MS (ESI) m/z: 295 (M+H)+.
