To a mixture of 3-(1-hydroxycyclopropyl)propyl methanesulfonate (170.7 mg, 0.877 mmol, from example 9) and N-(4-(7-hydroxyquinolin-4-yloxy)-3-fluorophenyl)-N-phenylcyclopropane-1,1-dicarboxamide (300 mg, 0.656 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 to 40° C. for 8 hrs. The reaction mixture was concentrated in vacuo and the residue was chromatographed with a silica gel column (4:1 (v/v) EtOAc/n-hexane) to afford the title compound as a white solid (364.1 mg, 74%).
