실험 절차

To the compound 146 (0.59 g, 0.81 mmol) in dichloromethane (50 mL) was added TFA (3 mL). The solution was stirred for 18 h then concentrated. The residue was partitioned between dichloromethane and 1M NaOH, and filtered to remove insolubles. The organic phase was collected, washed with 1M NaOH, brine, dried (MgSO4), filtered, and concentrated to afford title compound 147 (0.35 g, 69% yield). 1H NMR (400 MHz, DMSO-d6) δ (ppm): 10.40 (s, 1H), 10.01 (s, 1H), 8.55 (d, J=1.6 Hz, 1H), 8.51 (d, J=5.3 Hz, 1H), 8.31 (s, 1H), 8.22 (d, J=8.0 Hz, 1H), 7.92-7.87 (m, 2H), 7.65-7.61 (m, 2H), 7.52-7.43 (m, 2H), 7.17-7.12 (m, 2H), 6.64 (d, J=5.5 Hz, 1H), 3.77 (s, 2H), 3.40 (t, J=5.7 Hz, 2H), 3.23 (s, 3H), 2.64 (t, J=5.7 Hz, 2H), 1.46 (br s, 4H). MS (m/z): 630.1 (M+H).
