Reaction Steps

A mixture of 4-chloro-6-methoxy-7-(3-morpholin-4-yl-propoxy)-quinoline (prepared as described in WO 03/33472) (0.465 mg, 1.93 mmol), 6-bromo-1-fluoro-naphthalen-2-ol (Example 3a) (0.65 mg, 1.93 mmol) and DMAP (0.235 mg, 1.93 mmol, Aldrich) in toluene (in a microwave tube) was heated in a microwave oven (Personal Chemistry, Emrys Optimizer) at 180° C. for 2 h. The mixture was cooled to RT and diluted with 30 mL of EtOAc. The solution was washed with brine (2×10 mL), dried over Na2SO4 and concentrated in vacuo. The residue was further purified with silica gel column chromatography (40% to 100% EtOAc in hexanes) to give the title compound as an orange foam. MS (ESI, pos. ion) m/z: 541.1 (M+1). Mass Calc'd for C27H26BrFN2O4: 540.11.
