実験手順
tert-Butyl (S)-1-((R)-2,2,2-trifluoro-1-(3-(6-fluoro-7-methoxyquinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-ylcarbamate (109 mg, 0.194 mmol) was stirred in TFA (3 mL) for 1 hour and then concentrated. The residue was dissolved in minimum methanol and added dropwise to a 4N HCl in ether solution. The resulting solid was filtered and dried to yield (S)-1-((R)-2,2,2-trifluoro-1-(3-(6-fluoro-7-methoxyquinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-amine (67 mg, 74.8% yield) hydrochloride as an off-white solid. LCMS APCI (+) m/z 461 (M+H). Specific rotation: [α]20D=+1.07° (c=0.96, MeOH).
