Reaction Steps

A mixture of 4-chloro-6,7-dimethoxyquinoline (0.064 g, 0.28 mmol) and 2-fluoro-4-(2-(phenylamino)pyrimidin-5-yl)phenol (Step 3, 0.48 g, 0.17 mmol) in dioxane (1.0 mL) and pyridine (0.5 mL) was treated with a catalytic amount of DMAP (0.12 g, 0.1 mmol). The mixture was heated under microwave irradiation at 180° C. for 30 min. After cooling to RT, the mixture was diluted with NaOH (0.2 N, 6 mL), and the suspension was filtered. The resulting solid was further purified on silica with 0-5% (NH3-MeOH in DCM) to afford the title compound as a white solid. MS (ESI pos. ion) m/z: 469. Calc'd for C27H21FN4O3: 468.16.
