Reaction Steps

The title compound was prepared from 35 (4.5 mg, 0.010 mmol) following general procedure A. Flash chromatography (SiO2, 10% MeOH—CH2Cl2) afforded the title compound (3.4 mg, 85%) as a yellow solid: 1H NMR (DMSO-d6+0.1% TFA, 600 MHz) δ 8.29 (d, 1H, J=7.8 Hz), 8.17 (d, 1H, J=7.8 Hz), 8.08 (t, 1H, J=7.8 Hz), 7.57-7.55 (m, 4H), 7.36 (t, 2H, J=7.8 Hz), 7.29-7.25 (m, 2H), 4.02 (s, 4H); 13C NMR (DMSO-d6+0.1% TFA, 150 MHz) δ 202.1, 166.2, 164.7, 163.3, 150.0, 143.1, 142.2, 141.0, 139.9, 133.9, 131.1, 128.9, 128.0, 127.7, 127.5, 127.3, 126.7, 48.0, 39.8; HRMS-ESI-TOF m/z 400.1299 ([M+H]+, C23H17N3O4 requires 400.1292).
