Procedure

To a homogeneous mixture of 4-(1H-pyrrolo[2,3-b]pyridin-4-yloxy)-3-fluorobenzenamine (0.037 g, 0.15 mmol, Compound C of Example 1) and 2-chloro-N-(2,4-difluorophenyl)-4-methoxynicotinamide (0.045 g, 0.15 mmol), in anhydrous NMP (0.50 mL), was added HCl (4N in 1,4-dioxane, 0.15 mL, 0.60 mmol). The mixture was microwaved in a CEM Explorer PLS microwave system (300 W), with the temperature measured with an IR temperature sensor and maintained at 140° C. for six hours. The reaction mixture was partitioned between water and EtOAc. The aqueous layer was extracted twice with EtOAc, and the combined organic layers were concentrated in vacuo. The resultant residue was purified by preparative (RP) HPLC (YMC S10 ODS, 30×500 mm, 30 minute gradient from 50% to 90% aqueous methanol with 0.1% TFA). The appropriate fractions were combined and concentrated in vacuo to afford 2-(4-(1H-pyrrolo[2,3-b]pyridin-4-yloxy)-3-fluorophenylamino)-N-(2,4-difluorophenyl)-4-methoxynicotinamide (Example 15) (0.006 g) as an off-white solid and 2-(4-(1H-pyrrolo[2,3-b]pyridine-4-yloxy)-3-fluorophenylamino)-N-(2,4-difluorophenyl)-4-hydroxynicotinamide (Example 16) (0.042 g) as a white solid.
