4-Fluoro-2-methoxy-phenol (6.17 μL, 0.05 mmol), N-(3-sulfamoylphenyl)-2-(triazolo[4,5-b]pyridin-3-yloxy)quinoline-3-carboxamide (25 mg, 0.05 mmol) and K2CO3 (22.46 mg, 0.16 mmol) were combined in DMF (0.5 mL) and heated at 90° C. for 1 h. The reaction was diluted with DMF (0.5 mL), filtered, and purified by reverse phase HPLC (30-99% CH3CN/5 mM aqueous HCl) to provide 2-(4-fluoro-2-methoxy-phenoxy)-N-(3-sulfamoylphenyl)quinoline-3-carboxamide (61) (7.95 mg, 30%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ 10.86 (s, 1H), 8.73 (s, 1H), 8.40-8.35 (m, 1H), 8.07 (dd, J=7.8, 1.6 Hz, 1H), 7.88 (td, J=4.4, 2.1 Hz, 1H), 7.72 (ddd, J=8.4, 6.9, 1.5 Hz, 1H), 7.64-7.52 (m, 4H), 7.42 (s, 2H), 7.38 (dd, J=8.9, 6.0 Hz, 1H), 7.12 (dd, J=10.8, 2.9 Hz, 1H), 6.87 (td, J=8.5, 2.9 Hz, 1H), 3.70 (s, 3H), 8.76-8.68 (m, 1H) ppm. ESI-MS m/z calc. 467.09, found 468.3 (M+1)+; Retention time: 1.78 minutes (3 minutes run).
