A 16×100 mm resealable vial with stir-bar was charged with 1,2-dichloroethane (3.0 mL), 6-(6,7-dimethoxyquinolin-4-yloxy)-1-naphthoyl chloride (0.15 g, 0.38 mmol), and 5-amino-3-methylisoxazole (0.045 g, 0.46 mmol). To the suspension was added triethylamine (0.13 mL, 0.95 mmol) and N,N-dimethylaminopyridine (0.005 g, 0.04 mmol). The mixture stirred at 80° C. for 15 h and was then cooled to RT. The reaction mixture was concentrated and the residue was purified by column chromatography on silica gel (eluting with 2% methanol in dichloromethane) to afford 6-((6,7-bis(methoxy)-4-quinolinyl)oxy)-N-(5-methyl-3-isoxazolyl)-1-naphthalenecarboxamide as an off-white solid. MS (ESI, pos. ion) m/z: 456.1 (M+H). Mass Calc'd for C29H26FN3O5: 455.468
