実験手順

To a solution of compound 288 (230 mg, 0.32 mmol) in dichloromethane (7 mL) under nitrogen at room temperature was added trifluoroacetic acid (2.5 mL, 32 mmol). The reaction mixture was stirred for 16 h at room temperature. The solvent was removed under reduced pressure and a saturated aqueous solution of sodium bicarbonate was added. The aqueous phase was extracted with ethyl acetate (3×), the combined organic layers were concentrated. The residue was purified via Biotage (linear gradient 0-20%, methanol/dichloromethane; 25M column) to afford compound 289 as an off-white solid (75.3 mg, 0.122 mmol, 38.0%). 1H NMR (400 MHz, DMSO-d6) δ (ppm): 9.15 (s, 1H), 9.06 (s, 1H), 8.57 (d, J=1.6 Hz, 1H), 8.53 (d, J=5.6 Hz, 1H), 8.31 (s, 1H), 8.23 (d, J=8.0 Hz, 1H), 7.92-7.83 (m, 2H), 7.76 (dd, J=13.2, 2.4 Hz, 1H), 7.67-7.62 (m, 1H), 7.49-7.42 (m, 2H), 7.41-7.33 (m, 1H), 7.32-7.26 (m, 1H), 6.67 (d, J=5.6 Hz, 1H), 3.78 (s, 2H), 3.54-3.34 (2H, hidden under water signal), 3.24 (s, 3H), 2.65 (t, J=5.6 Hz, 2H), 1.65 (d, J=13.2 Hz, 6H). MS (m/z): 620.4 (M+H).
