Reaction Steps

To a solution of N-(3-fluoro-4-((7-(2-hydroxy-2-methylpropoxy)quinolin-4-yl)oxy)phenyl)-1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamide (300 mg, 0.54 mmol) in DCM/MeOH (30 mL, v/v=1:2) was added 1 N HCl in EtOAc (5.4 mL). The mixture was stirred at room temperature for 30 minutes. The solid was collected by filtration, washed with ethanol (20 mL) to give the title compound as a white solid (304 mg, 95.2%)
