実験手順

The title compound was prepared using the procedure as described in Example 1H, substituting the product of Example 23C (128 mg, 0.453 mmol) for the product of Example 1F and the product of Example 9A (95 mg, 0.544 mmol) for the product of Example 1G. The crude product was purified by flash chromatography eluting with 2% to 5% CH3OH/CH2Cl2 followed by 100% EtOAc which gave 116 mg (64%) of the title compound as a tan solid. 1H NMR (DMSO-d6) δ 9.13 (s, 1H), 7.61 (d, J=7.5 Hz, 1H), 7.46 (d, J=8.1 Hz, 2H), 7.30 (s, 1H), 7.23 (m, 3H), 7.11 (t, J=7.8 Hz, 1H), 6.85 (d, J=7.5 Hz, 1H), 3.58 (m, 1H), 3.11 (m, 1H), 2.99 (s, 3H), 2.87 (m, 2H), 2.56 (m, 1H), 2.31 (s, 3H), 2.01 (m, 1H), 1.66 (m, 1H); MS (ESI+) m/z 398 (M+H)+.
