Vorschrift

2-(2-(6-((R)-1-((S)-3-(tert-butoxycarbonylamino)pyrrolidin-1-yl)-2,2,2-trifluoroethyl)-[1,2,4]triazolo[4,3-a]pyridin-3-yl)-6-fluoroquinolin-7-yloxy)ethyl acetate (40 mg, 0.063 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 2-(2-(6-((R)-1-((S)-3-aminopyrrolidin-1-yl)-2,2,2-trifluoroethyl)-[1,2,4]triazolo[4,3-a]pyridin-3-yl)-6-fluoro quinolin-7-yloxy)ethyl acetate (27 mg, 80% yield) hydrochloride as an off-white solid. LCMS APCI (+) m/z 505 (M+H).
