Versuchsvorschrift

To a stirred solution of tert-butyl (S)-3-methyl-1-((S)-2,2,2-trifluoro-1-(6-((E)-2-((8-isopropoxyquinolin-2-yl)methylene)hydrazinyl)pyridin-3-yl)ethyl)pyrrolidin-3-ylcarbamate (1.33 g, 2.27 mmol) in DCM (20 mL) was added iodo benzene diacetate (0.949 g, 2.95 mmol). The reaction mixture was stirred at ambient temperature for 2 hours and then partitioned between ethyl acetate and saturated aqueous NaHCO3. The aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried and concentrated. The residue was purified by chromatography (1:3 hexane/ethyl acetate) to give tert-butyl (S)-3-methyl-1-((S)-2,2,2-trifluoro-1-(3-(8-isopropoxyquinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-ylcarbamate (1.30 g, 98%).
