To a solution of tert-butyl (3S)-1-((1R)-2,2,2-trifluoro-1-(3-(3-fluoro-7-(2-methoxyethoxy)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-ylcarbamate (0.096 g, 0.159 mmol) in DCM (0.5 mL) was added 5 N HCl (0.530 mL, 2.65 mmol) in IPA. The reaction mixture was stirred at ambient temperature for 2 hours. The solvent was removed under reduced pressure. The crude residue was suspended in ACN (5 mL) and stirred at ambient temperature for 10 minutes. The solid was collected by filtration to give (3S)-1-((1R)-2,2,2-trifluoro-1-(3-(3-fluoro-7-(2-methoxyethoxy)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-amine (0.078 g, 0.135 mmol, 85% yield) as a solid. LCMS APCI (+) m/z 505 (M+H).
