반응 단계
To a solution of the compound of Example 14 (200 mg) in 1,4-dioxan (10 mL) was added 2M HCl(aq) (0.5 mL) and the reaction mixture heated at 70° C. for 1 h. The reaction was diluted with water (30 mL), extracted with EtOAc (3×20 mL) and the EtOAc extracts dried (MgSO4) and concentrated in vacuo. The crude residue was purified by chromatography on silica (0-5% EtOAc in DCM) to give the title compound as a white solid (90 mg). δH (DMSO-d6) 8.21 (1H, bs), 7.96 (1H, d, J 9.6 Hz), 7.63-7.47 (3H, m), 7.43-7.36 (2H, m), 7.25-7.11 (2H, m), 7.10-7.03 (2H, m), 6.82-6.71 (1H, m), 6.46 (1H, d, J 9.6 Hz), 6.44 (1H, s). LCMS (ES+) RT 3.54 minutes, 319 (M+H)+.
