Procedure

To a mixture of (4-oxaspiro[2.4]heptane-6-yl)methanesulfonate (168 mg, 0.877 mmol) and N-(5-(7-hydroxyquinolin-4-yloxy)pyridin-2-yl)-N-phenylcyclopropane-1,1-dicarboxamide (300 mg, 0.682 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, then the reaction mixture was warmed up to 40° C. for 8 hrs. The reaction mixture was concentrated in vacuo and the residue was chromatographed with a silica gel column (2:1 (v/v) EtOAc/n-hexane) to afford the title compound as a white solid (73 mg, 20%).
