Procedure

To a solution of N-(3-fluoro-4-(7-hydroxy-6-methoxyquinolin-4-yloxy)phenyl)-N-phenylcyclopropane-1,1-dicarboxamide (260 mg, 0.534 mmol) in DMA (3 mL) was added 3-(7-hydroxy-5-azaspiro[2.4]heptane-5-yl)propyl methanesulfonate (266 mg, 1.068 mmol) and Cs2CO3 (520 mg, 1.602 mmol). The reaction was then stirred at rt for 2 days. The solvent was removed and the residue was partioned between saturated NaHCO3 aqueous solution (15 mL) and CHCl3 (30 mL). The organic layer was dried over anhydrous Na2SO4, filtered and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (100:15:1(v/v/v)EtOAc/CH3OH/Et3N) to afford the desired compound as a pale yellow solid (264 mg, 77%).
