Reaction Steps

To a solution of compounds 1-((4-(4-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamido)-2-fluorophenoxy)quinolin-7-yloxy)methyl)cyclopropyl acetate (110 mg, 0.18 mmol) in 8 mL of methanol was added KOH (100 mg, 1.78 mmol) slowly. After stirring at rt for 0.5 hr, the reaction mixture was filtered and the solid was washed with ethyl acetate (10 mL×2) to give the title compound as a white solid (100 mg, 29%).
