Procedure
To a stirred solution of 15 (1.82 g, 4.57 mmol, 1.0 equiv.) in MeOH (14 mL, 0.33 M) was added 10% aqueous HCl (14 mL). The reaction mixture was stirred overnight at room temperature. The MeOH was evaporated, and the resulting aqueous solution was made basic (pH>12) by the addition of 1M NaOH. The aqueous solution was extracted with DCM (4×25 mL). The combined organic layers were washed with brine (25 mL), dried over MgSO4, filtered, and concentrated to yield 1{31} (726 mg, 45%) as a yellow oily solid, which was used without further purification. 1H-NMR (500 MHz, CDCl3): δ 8.16 (br s, 1H), 7.75-7.71 (m, 4H), 7.53 (t, 1H, J=7.5 Hz), 7.42 (t, 2H, J=7.5 Hz), 7.38 (d, 2H, J=8.0 Hz), 3.85 (br s, 2H), 3.53 (s, 2H), 3.03 (s, 2H), 2.51 (br s, 4H), 2.45 (br s, 4H). 13C-NMR (125 MHz, CDCl3): δ 196.2, 170.2, 142.9, 137.4, 136.2, 132.2, 130.0, 129.8, 128.6, 128.1, 62.2, 60.4, 53.4, 52.9.
