To a solution of N-(5-(7-hydroxyquinolin-4-yloxy)pyridin-2-yl)-2,3-dihydro-1,5-dimethyl-3-oxo-2-phenyl-1H-pyrazole-4-carboxamide (200.6 mg, 0.44 mmol) and cesium carbonate (684.6 mg, 2.1 mmol, Aladdin) in N,N-dimethylacetamide (1 mL) was added (N-(4-oxaspiro[2.4]heptane-6-yl)-tert butoxycarbonylamino)propyl methanesulfonate (0.63 mmol) in N,N-dimethylacetamide (5 mL). After stirring at 40° C. for 2 days, the reaction mixture was concentrated in vacuo. The residue was chromatographed with a silica gel column (1:4 (v/v) n-hexane/EtOAc) to give the title compound as a white solid (200 mg, 62.5%).
