실험 절차

To a vial containing the title compound from Example 22 Step B (0.12 g, 0.48 mmol), the title compound from Example 71 Step C (0.13 g, 0.59 mmol), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (6.8 mg, 9.6 μmol), and potassium carbonate (0.200 g, 1.44 mmol) were added tert-butanol (5.3 mL) and water (0.67 mL). The vial was flushed with nitrogen, sealed tightly and heated to 80° C. overnight. The reaction solution was then cooled to room temperature and concentrated under reduced pressure. The resulting material was diluted with acetonitrile and purified by HPLC (C18 column, 10 to 100% acetonitrile/water, both 0.1% v/v trifluoroacetic acid). Fractions containing product were combined, aqueous 1 N HCl solution was added, and the resulting solution concentrated under reduced pressure to provide the title compound: LCMS m/z 347.00 [M+H]+; 1H NMR (500 MHz, CD3OD) δ 10.1 (s, 1H), 9.21 (s, 1H), 9.02 (s, 1H), 8.99 (s, 1H), 8.12-8.03 (m, 3H), 3.70 (s, 3H), 3.51-3.48 (m, 2H), 3.41-3.38 (m, 2H), 1.85-1.82 (m, 2H), 1.59-1.56 (m, 2H).
