Reaction Steps
To a stirred solution of 4-(1H-pyrrolo[2,3-b]pyridin-4-yloxy)-3-fluorobenzenamine (24 mg, 0.1 mmol, Compound B of Example 132), 2-hydroxynicotinic acid (27 mg, 0.2 mmol), and HATU (76 mg, 0.2 mmol) in DMF (1 mL) was added DIPEA (0.1 mL) and DMAP (5 mg). The resulting mixture was stirred at rt for 2 h and concentrated in vacuo. The residue was was purified by preparative HPLC to give the desired product (8 mg, 22%) as a white solid. LC/MS(ESI+) m/z 365 (M+H)+.
