Procedure
To a solution of N-(5-(7-((N-(4-oxaspiro[2.4]heptane-6-yl)-tert butoxycarbonylamino)propoxy)quinolin-4-yloxy)pyridin-2-yl)-2,3-dihydro-1,5-dimethyl-3-oxo-2-phenyl-1H-pyrazole-4-carboxamide (50 mg, 0.069 mmol) in dry THF (2 mL) was added 2 M HCl/THF (8 mmol). After stirring at room temperature for 4 hrs, 10 mL of saturated NaHCO3 aqueous solution was added to quench the reaction. The mixture was extracted with EtOAc (15 mL×2). The combined organic phases were dried over Na2SO4, concentrated in vacuo. The crude product was chromatographed with a silica gel column (5:1 (v/v) EtOAc/MeOH) to give the title compound as a white solid (30 mg, 69%).
