Reaction Steps

8-Chloro-5H-benzo[c][1,8]naphthyridin-6-one (50 mg, 0.22 mmol), 4-methoxyphenylboronic acid (66 mg, 0.43 mmol), palladium(II) acetate (2 mg, 0.01 mmol), 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (9 mg, 0.02 mmol), and sodium tert-butoxide (63 mg, 0.65 mmol) were dissolved in dioxane/H2O (2.2 mL, 10/1, v/v), and stirred overnight at 100° C. The reaction mixture was diluted with MeOH, filtered through a membrane plug, and purified via prep-LC-MS to provide 14 (10 mg, 15% yield) as a white solid. LC-MS (M+H=303, obsd.=303). 1H NMR (400 MHz, d6-DMSO): δ 12.11 (s, 1H), 8.84 (d, 1H), 8.61 (d, 1H), 8.52 (dd, 1H), 8.18 (dd, 1H), 7.80 (d, 2H), 7.34 (dd, 1H), 7.10 (d, 2H), 6.93 (s, 1H), 3.83 (s, 3H).
