실험 절차

To a solution of the 6-((6-(1-ethoxyvinyl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-1-yl)methyl)-5,7-difluoroquinoline (6.0 mg, 0.45 mmol) in acetic acid, 3N HCl (0.1 mL) was added. The solution stirred at it for 2 h. Solvents were removed under reduced pressure. The residue was diluted with water, treated with aqueous NaHCO3 solution, extracted with DCM. The organic layer was washed sequentially with NaHCO3 (aq.) and brine, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography with Hexane:ethyl acetate to give yellow solid 1-(1-((5,7-difluoroquinolin-6-yl)methyl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-6-yl)ethanone (3.5 mg), yield 63%. LCMS (method B): [MH]+=340.9, tR=2.09 min.
