실험 절차

A solution of tert-butyl (S)-1-((S)-1-(3-(7-ethoxy-6-fluoro quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)-3-methylpyrrolidin-3-ylcarbamate (5.406 g, 9.185 mmol) in DCM (40 mL) was added 4M HCl in dioxane (22.96 mL, 91.85 mmol) and stirred at ambient temperature for 1.5 h. The filtered precipitate was dissolved in water and basified (1N NaOH), extracted with ethyl acetate (3×200 mL), washed with brine (200 mL), dried (MgSO4), filtered concentrated under reduced pressure and the residue purified by flash chromatography (1 column volume DCM, increasing to 10% methanol/DCM over 2 column volumes, holding for 3 column volumes, then switching to 10% [10% NH4OH/Methanol]/DCM for 7 column volumes) to give (S)-1-((S)-1-(3-(7-ethoxy-6-fluoroquinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)-2,2,2-trifluoroethyl)-3-methylpyrrolidin-3-amine (4.13 g, 8.45 mmol, 92.05% yield). MS APCI (+) m/z 489 (M+1) detected. Specific rotation: [α]20D=−0.87° (c=1.02, MeOH).
