실험 절차

To a stirred solution of tert-butyl (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-ylcarbamate (Example 123, Step A; 100 mg, 0.169 mmol) and (S)-2-(tert-butoxycarbonylamino)-3-methylbutanoic acid (44.1 mg, 0.203 mmol) in DCM (2 mL) was added DMAP (41.4 mg, 0.339 mmol) and DCC (41.9 mg, 0.203 mmol) under nitrogen. The reaction mixture was stirred at ambient temperature for 4 hours and then poured into water. The mixture was extracted with DCM. The combined organic layers were washed with saturated aqueous NaHCO3 solution and brine, dried, and concentrated under reduced pressure. The residue was purified by reverse phase preparative HPLC (5-95% acetonitrile/water) to give (S)-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-fluoro quinolin-7-yloxy)ethyl 2-(tert-butoxycarbonylamino)-3-methylbutanoate (110 mg, 82%).
