Procedure

To a solution of N-(3-fluoro-4-(7-hydroxy-6-methoxyquinolin-4-yloxy)phenyl)-N-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide (240 mg, 0.475 mmol) in DMA (3 mL) was added 3-(7-hydroxy-5-azaspiro[2.4]heptane-5-yl)propyl methanesulfonate (236 mg, 0.95 mmol) and Cs2CO3 (463 mg, 1.425 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 separated, 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 white solid (250 mg, 80%).
