To a solution of 2-oxo-5-phenyl-1,2-dihydropyridine-3-carboxylic acid (35 mg, 0.16 mmol), HOBT (25 mg), and EDCI.HCl (80 mg, 0.42 mmol) in DMF (3.0 mL) at room temperature was added 4-(1H-pyrrolo[2,3-b]pyridin-4-yloxy)-3-fluorobenzenamine (30 mg, 0.12 mmol, Compound B of Example 132). The mixture was stirred at room temperature overnight and concentrated in vacuo. The residue was purified by preparative HPLC to afford the desired product (12 mg, 13%) as a light brown solid. 1H NMR (CD3OD) δ 8.81 (d, 1H, J=2.8 Hz), 8.17 (d, 1H, J=6.6 Hz), 8.00 (dd, 1H, J=12.6, 2.2 Hz), 7.94 (d, 1H, J=3.3 Hz), 7.52–7.27 (m, 7H), 6.80 (d, 1H, J=9.3 Hz), 6.72 (d, 1H, J=6.6 Hz), 6.54 (d, 1H, J=3.8 Hz); MS(ESI+) m/z 441.1 (M+H)+.
