Procedure
To a mixture of (4-oxaspiro[2.4]heptane-6-yl)methanesulfonate (168 mg, 0.877 mmol, from example 6) and N-(4-(7-hydroxyquinolin-4-yloxy)-3-fluorophenyl)-N-phenylcyclopropane-1,1-dicarboxamide (300 mg, 0.584 mmol) in 5 mL of N,N-dimethylacetamide was added cesium carbonate (893 mg, 2.74 mmol). After stirring at room temperature for 36 hrs, the reaction mixture was warmed up to 40° C. and continued to stir for 8 hrs. The reaction mixture was concentrated in vacuo and the residue was chromatographed with a silica gel column (1:1 (v/v) EtOAc/n-hexane) to afford the title compound as a white solid (65 mg, 18%).
