Reaction Steps

Palladium on carbon (10%, 5 mg) was added to 8a (120 mg, 0.35 mmol) in degassed MeOH (3.5 mL) and the solution was placed under an atmosphere of H2. After 12 h, the solution was diluted with DCM and filtered through Celite. The eluent was concentrated to afford a yellow solid, which was purified by column chromatography (SiO2, 100:5, DCM:MeOH) to afford phenol 9a (64 mg, 0.25 mmol, 79%) as a pale yellow amorphous solid. 1H NMR (400 MHz, CDCl3) δ 7.25-7.14 (m, 5H), 7.11-7.05 (m, 1H), 6.90 (d, J=8.3 Hz, 1H), 6.64 (d, J=8.3 Hz, 1H), 6.59 (d, J=2.5 Hz, 1H), 5.61 (t, J=5.5 Hz, 1H), 3.12-3.02 (m, 2H), 2.55 (t, J=7.1 Hz, 2H), 1.66 (s, 3H); 13C NMR (100 MHz, CDCl3) δ 171.2, 155.2, 143.4, 141.6, 130.8, 129.1, 128.4, 127.2, 127.2, 117.4, 115.0, 41.1, 31.8, 23.2; HRMS m/z: [M+Na+] for C16H17NO2Na, calcd, 278.1151. found, 278.1155.
