실험 절차

To a solution of 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-yl)oxy)ethanol (125 mg, 0.255 mmol) in DMF (1.5 mL) was added a solution of (5-methyl-2-oxo-1,3-dioxol-4-yl)methyl 4-nitrophenyl carbonate (prepared according to procedures described in J. Med. Chem. 1999, 42, 3994-4000, 71.2 mg, 0.255 mmol) in DMF (1 mL). The reaction mixture was stirred at ambient temperature for 30 minutes. The reaction was partitioned between EtOAc and water. The aqueous layer was extracted with EtOAc. The combined organic layers were washed with water and brine, dried and concentrated. The residue was purified by flash chromatography on silica gel (DCM:MeOH, 70:1 to 40:1) to give (5-methyl-2-oxo-1,3-dioxol-4-yl)methyl ((S)-1-((R)-2,2,2-trifluoro-1-(3-(6-fluoro-7-(2-hydroxyethoxy)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-yl)carbamate (131 mg, 80%). LCMS APCI (+) m/z 647 (M+H).
