Reaction Steps

9-Chloro-5H-benzo[c][1,8]naphthyridin-6-one (50 mg, 0.22 mmol), 2-trifluoromethylbenzylamine (76 mg, 0.43 mmol), palladium(II) acetate (2 mg, 0.01 mmol), 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl (10 mg, 0.02 mmol), and sodium tert-butoxide (63 mg, 0.65 mmol) were suspended in dioxane (2 mL), and stirred overnight at 100° C. The reaction mixture was concentrated, diluted with H2O/EtOAc, and filtered. The precipitate was washed with EtOAc/H2O and purified via prep-LC-MS. The purified product was converted to the HCl salt via dissolving in MeOH, addition of 1 M HCl/ether, and concentration. The HCl salt was triturated in CH2Cl2, filtered, washed with CH2Cl2, and dried under vacuum to provide 47 (22 mg, 25% yield) as a yellow solid. LC-MS (M+H=370, obsd.=370). 1H NMR (400 MHz, d6-DMSO): δ 11.52 (s, 1H), 8.46 (dd, 1H), 8.41 (m, 1H), 8.02 (d, 1H), 7.79 (d, 1H), 7.64 (m, 3H), 7.50 (m, 1H), 7.33 (d, 1H), 7.24 (dd, 1H), 6.95 (dd, 1H), 4.67 (s, 2H).
