tert-butyl (S)-1-((R)-1-(3-(7-ethoxy-6-fluoro quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)pyrrolidin-3-ylcarbamate (265 mg, 0.461 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)-1-(3-(7-ethoxy-6-fluoro quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)pyrrolidin-3-amine (186 mg, 85.0% yield) hydrochloride as an off-white solid. LCMS APCI (+) m/z 475 (M+H). Specific rotation: [α]24D=1.84° (c=1.03, MeOH).
