A mixture of 3-fluoro-4-(2-methyl-1H-pyrrolo[2,3-b]pyridin-4-yloxy)benzenamine (17 mg, 0.066 mmol), 1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid (20 mg, 0.086 mmol) in DMF (0.5 mL) was stirred with BOP reagent (50 mg, 0.11 mmol) and triethylamine (0.01 mL) at 50° C. for 1 h. The reaction mixture was cooled to room temperature and diluted with water. The precipitate was collected and washed with water. The crude product was purified by preparative HPLC and the appropriate fractions were collected, neutralized and concentrated in vacuo to give the title compound (7.85 mg, 25%) as a solid. 1H NMR (DMSO-d6) δ 12.07 (s, 1H), 11.56 (s, 1H), 8.49 (d, 1H, J=6.2 Hz), 8.12 (d, 1H, J=6.2 Hz), 7.98 (dd, 1H, J=10.4, 2.6 Hz), 7.95 (d, 1H, J=5.5 Hz), 7.61 (m, 2H), 7.43 (m, 3H), 7.29 (t, 1H, J=8.40 Hz), 6.72 (t, 1H, J=6.2 Hz), 6.36 (d, 1H, J=5.5 Hz), 5.88 (s, 1H), 2.32 (s, 3H); MS(ESI+) m/z 473 (M+H)+.
