Reaction Steps
To a flask charged with 3-(benzyloxy)-6-(difluoro(8-fluoro-6-(1-methyl-1H-pyrazol-4-yl)-[1,2,4]triazolo[4,3-a]pyridin-3-yl)methyl)quinoline (10 mg, 20 μmol) was added trifluoroacetic acid (1.5 mL, 20 mmol). The resulting solution was heated at 65° C. for 18 h. The solution was concentrated for purification by MPLC using 98:2 CH2Cl2: MeOH to 90:10 CH2Cl2: MeOH gradient to afford 6-(difluoro(8-fluoro-6-(1-methyl-1H-pyrazol-4-yl)-[1,2,4]triazolo[4,3-a]pyridin-3-yl)methyl)quinolin-3-ol (3.6 mg, 44% yield) as a colorless solid. LRMS (ESI) m/z calcd for C20H14F3N6O (M+H) 411.1. found 411.3.
