Procedure
To a solution of (R)-1-(4-(4-(6,7-dimethoxyquinolin-4-yloxy)-3-fluorophenylcarbamoyl)-5-methyl-3-oxo-2-phenyl-2,3-dihydropyrazol-1-yl)propan-2-yl-2-(tert-butoxycarbonyl amino)acetate (100 mg, 0.137 mmol) in EtOAc (15 mL) was added 3 mL of saturated HCl in EtOAc (3 mL). The reaction mixture was stirred at rt overnight. The solid formed was collected and was crystallized in MeOH/EtOAc (20 mL, v/v=1:5). The product was further washed with EtOAc (5 mL×3) and dried under vacuum overnight to afford the title compound as a white solid (88 mg, 83%).
