실험 절차

To a suspension of 404 (221 mg, 0.365 mmol) in DCM (5 mL) was added TFA (1 mL) and the reaction mixture was stirred for 4 h then concentrated, diluted with water and 1M NaOH to pH 11. The solid was collected by filtration, rinsed with water and dried. The residue was purified by Biotage (SNAP 25 g cartridge; 2% of ammonium hydroxide in MeOH/DCM: 10/90 to 30/70), to afford the title compound 405 (155 mg, 84% yield) as a beige solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 8.77 (s, 1H), 8.55 (brd, J=1.6 Hz, 1H), 8.52 (d, J=5.6 Hz, 1H), 8.35 (s, 1H), 8.27 (d, J=7.2 Hz, 1H), 7.91 (dd, J=8.0, 2.4 Hz, 1H), 7.73 (dd, J=13.6, 2.4 Hz, 1H), 7.38 (t, J=9.0 Hz, 1H), 7.24-7.18 (m, 1H), 6.65 (d, J=5.2 Hz, 1H), 6.62 (brd, J=2.8 Hz, 1H), 4.48 (s, 2H), 4.40-4.41 (m, 1H), 3.56-3.49 (m, 2H), 3.47-3.50 (m, 2H), 2.58-2.51 (m, 1H), 0.68-0.62 (m, 2H), 0.47-0.41 (m, 2H). MS (m/z): 506.14 (M+H).
