実験手順
A solution of Example 14D (92.0 mg, 0.176 mmol) in dichloromethane (4 mL) was treated with trifluoroacetic acid (0.14 mL, 1.8 mmol) and the mixture was stirred for 3 hours and concentrated. The residue was dissolved in 2 mL of methanol and slowly treated with 3 mL 2M hydrogen chloride in ether. The suspension was stirred for 15 minutes and diluted with ether. The solids were filtered, washed with ether, treated with aqueous sodium bicarbonate, filtered, washed with water and concentrated to give the title compound. 1H NMR (500 MHz, dimethylsulfoxide-d6) δ 2.23-2.29 (m, 2H), 2.92 (t, J=5.6 Hz, 2H), 3.38-3.46 (m, 1H), 5.64 (s, 2H), 6.33 (d, J=1.9 Hz, 1H), 6.53 (s, 1H), 7.11-7.17 (m, 3H), 7.19-7.25 (m, 1H), 7.40 (td, J=7.9, 6.1 Hz, 1H), 7.59 (dd, J=8.3, 1.6 Hz, 1H), 7.83 (d, J=8.3 Hz, 1H), 7.90 (d, J=1.6 Hz, 1H), 8.22 (d, J=5.0 Hz, 1H), 8.54 (s, 1H), 11.81 (bs, 1H) MS (ESI+) m/z 424.2 (M+H)+.
