Procedure

To a solution of N-(5-(7-hydroxyquinolin-4-yloxy)pyridin-2-yl)-1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamide (300 mg, 0.642 mmol) in DMA (3 mL) was added 3-(7-hydroxy-5-azaspiro[2.4]heptane-5-yl)propyl methanesulfonate (240 mg, 0.963 mmol) and Cs2CO3 (417 mg, 1.284 mmol). The reaction was stirred at rt for 24 hrs. 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 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 title compound as a white solid (259 mg, 65%).
