Procedure

4-Chloro-7-benzyloxy-6-methoxy-quinoline (WO2008112407, 1.5 g) was mixed with DMAP (1.5 eq), 2-methyl-4-fluoro-5-hydroxyindole (WO0047212) (1 eq) in dioxane (20 ml). The reaction was refluxed for three days and diluted with EtOAc, water and extracted with EtOAc three times. The combined organic layer was washed with water, brine and dried. The solution was evaporated and purified with silica gel column to give 4-(4-fluoro-2-methyl-1H-indol-5-yloxy)-6-methoxy-7-benzyloxyquinoline (600 mg).
