6-Fluoro-2-methylquinoline-4-carbonyl chloride (100 mg) and 4-amino-5-methyl-3-phenylisoxazole (200 mg) were dissolved in dichlorormethane (10 mL) and pyridine (0.3 mL). The reaction solution was heated at 70° C. overnight and then diluted with ethyl acetate (60 mL). The organic solution was washed with water (60 mL), dried, evaporated and purified by flash column chromatography (EtOAc/hexanes=1/1) to give 6-fluoro-2-methyl-N-(5-methyl-3-phenylisoxazol-4-yl)-4-quinolinecarboxamide (100 mg) as a white solid. 1H NMR (CDCl3): δ 2.58 (s, 3H), 2.76 (s, 3H), 7.14 (s, 1H), 7.44 (s, 1H), 7.49 (m, 4H), 7.67 (m, 2H), 7.82 (dd, J=2.7 and 9.9 Hz, 1H), 8.07 (dd, J=5.7 and 9.3 Hz, 1H); 19F NMR (282 MHz, CDCl3): δ-111.63; LCMS: ret. time: 21.32 min.; purity: 99.44%; MS (m/e): 362.06 (MH+).
