To a solution of N-(3-fluoro-4-(7-hydroxyquinolin-4-yloxy)phenyl)-1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamide (200 mg, 0.413 mmol) in DMA (3 mL) was added 3-(7-hydroxy-5-azaspiro[2.4]heptane-5-yl)propyl methanesulfonate (154 mg, 0.619 mmol) and Cs2CO3 (268 mg, 0.826 mmol). The reaction was then stirred at rt for 40 hrs. The solvent was removed and the residue was partioned between saturated NaHCO3 aqueous solution (10 mL) and CHCl3 (25 mL). The organic layer was dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by a silica gel column chromatography (100:15:1(v/v/v)EtOAc/CH3OH/Et3N) to afford a pale yellow solid (192 mg, 73%).
