A mixture of 4-Chloro-6,7-dimethoxy-quinoline (0.19 g, 0.85 mmol), 4-(6-benzyl-pyridazin-3-yl)-2-fluoro-phenol (Step 3, 0.2 g, 0.71 mmol) and DMAP (0.1 g, 0.85 mmol) in 6 mL of toluene was heated in a microwave (Personal Chemistry, Emrys Optimizer) at 180° C. for 2 h. The mixture was cooled to RT and diluted with 60 mL of EtOAc. The solution was washed with 20 mL of brine 2×, dried over Na2SO4 and concentrated in vacuo. The residue was further purified with silica gel column chromatography (50% to 100% EtOAc in hexanes) to provide title compound as a white solid. MS (ESI pos. ion) m/z: 487.3 (M+H). Calc'd Exact Mass for C28H22FN3O3: 467.49.
