Procedure

A mixture of compound 347 (50 mg, 97 mmol) and lithium hydroxide, monohydrate (14 μl, 486 μmol) in methanol (9 mL) and water (3 mL) was heated at reflux for 2 h. After cooling, the crude mixture was subjected to reverse phase preparative HPLC (acetonitrile/H2O containing 0.1% TFA each, 40 min from 10 to 40%). Lyophilization provided compound 349 (40 mg) as a light yellow solid (TFA salt). 1H NMR (400 MHz, DMSO-d6) δ ppm 10.84 (1 H, s), 9.62 (1 H, s), 9.38 (1 H, s), 8.68 (1 H, d, J=5.9 Hz), 8.58 (1 H, d, J=6.3 Hz), 8.26-8.48 (2 H, m), 7.89-8.01 (1 H, m), 5.40 (1 H, quin, J=8.9 Hz), 2.75-4.63 (12 H, m), 2.39-2.47 (2 H, m), 2.01-2.23 (4 H, m), 1.70-1.87 (2 H, m). LCMS-ESI (POS), M/Z, M+1: Found 487.3.
