Reaction Steps

To a solution of 1-(2-(4-(4-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxamido)-2-fluorophenoxy)quinolin-7-yloxy)ethyl)cyclopropyl 2-(tert-butoxy-carbonylamino)acetate (190 mg, 0.262 mmol) in 8 mL of ethyl acetate was added a solution of HCl in EtOAc (0.93 mol/L, 5 mL) dropwise. The reaction mixture was stirred at rt for 30 minutes and then filtered. The solid was washed with ethyl acetate (20 mL×3) to afford the title compound as a white solid (54 mg, 30.3%).
