Procedure

To a mixture of 3-(1-hydroxycyclopropyl)propyl methanesulfonate (240 mg, 1.2 mmol) and N-(4-(7-hydroxyquinolin-4-yloxy)-3-fluorophenyl)-2,3-dihydro-1,5-dimethyl-3-oxo-2-phenyl-1H-pyrazole-4-carboxamide (300 mg, 0.62 mmol) in 5 mL of N,N-dimethylacetamide was added cesium carbonate (470 mg, 2.4 mmol, Aladdin). After stirring at rt for 12 hrs, the reaction mixture was warmed to 40° C. and stirred for additional 6 hrs. The reaction mixture was diluted with 20 mL of water and extracted with ethyl acetate (40 mL×3). The combined organic phases were dried over Na2SO4, concentrated in vacuo and chromatographed with a silica gel column (5:1 (v/v) EtOAc/n-Hexane) to provide the title compound as a white solid (68 mg, 19%).
