Procedure

To a solution of compound 5-A (27 mg, 0.049 mmol), dissolved in MeOH (1.0 mL), was added 3N NaOH (24 μL, 0.073 mmol) and the reaction mixture was refluxed for 18 hours. The reaction was cooled and the solvent evaporated under reduced pressure. The residual solid was partitioned between H2O and EtOAc, the organic layer collected, dried over Na2SO4, filtered and the solvent evaporated under reduced pressure. The crude material was purified by reverse-phase semi-prep HPLC (method 3) eluting with a 50% MeCN—H2O (0.1% TFA) to 70% MeCN—H2O (0.1% TFA) gradient to afford 11.2 mg of compound 10 as a white solid. 1H-NMR (CD3OD, 400 MHz): δ 7.71-7.86 (m, 1H), 7.54-7.61 (m, 1H), 7.29-7.42 (m, 4H), 7.10-7.23 (m, 2H), 4.72-4.85 (br s, 2H), 3.63-3.79 (m, 2H), 2.95-3.11 (m, 2H), 2.44-2.61 (m, 1H), 1.99 (s, 3H), 1.87-1.96 (m, 2H), 1.60-1.81 (m, 2H); MS (method 2): m/z 528.9 (MH+); HPLC (method 1): Rt 6.68 minutes.
