Procedure

To a solution of 4-(1H-pyrrolo[2,3-b]pyridin-4-yloxy)-3-fluoroaniline (17 mg, 0.07 mmol, Compound C of Example 1) and 5-bromo-N-(2,4-difluorophenyl)-2-fluoronicotinamide (26 mg, 0.08 mmol) in 1 mL of NMP was added 4N HCl in 1,4-dioxane (0.05 mL, 0.20 mmol). The mixture was stirred at 110° C. for 4 d. After cooling, the mixture was purified on preparative (RP) HPLC to give fractions containing the desired product. The fractions were pooled and concentrated in vacuo and the residue was treated with 10 mL of 1N HCl and it was concentrated again to give the title compound (8.0 mg, 18% yield). 1H NMR (DMSO-d6) δ 10.66 (s, 1H), 10.62 (s, 1H), 8.55 (d, 2H, J=7.5 Hz), 8.06 (d, 1H, J=13.4 Hz), 7.35-7.62 (m, 5H), 7.16 (m, 1H), 6.62 (d, 1H, J=6.0 Hz), 6.43 (s, 1H); MS(ESI+) m/z 554.15, 556.14 (M+H)+.
