A solution of 3-((4-((6-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamido)pyridin-3-yl)oxy)pyridin-2-yl)carbamoyl)cyclobutyl acetate (40 mg, 0.072 mmol) in MeOH (2.5 mL) was cooled to 0° C., then NaOH (6 mg, 0.144 mmol) was added to the mixture. The reaction was stirred at rt for 1 hour, then concentrated in vacuo. The residue was washed with water (5 mL) and ether (5 mL), then filtered to give the title compound as a white solid (17 mg, 42%).
