To tert-butyl (S)-1-((R)-2,2,2-trifluoro-1-(6-((E)-2-((6-fluoro-7-isopropoxyquinolin-2-yl)methylene)hydrazinyl)pyridin-3-yl)ethyl)pyrrolidin-3-ylcarbamate (700 mg, 1.19 mmol) in DCM was added iodosobenzene acetate (496 mg, 1.54 mmol) and the reaction was stirred at ambient temperature for 2 hours. After concentration, the residue was purified by reverse phase chromatography (SP4, 25M, eluting with a gradient of water/ACN 100:0 to 0:100, 25 column volumes) to yield tert-butyl (S)-1-((R)-2,2,2-trifluoro-1-(3-(6-fluoro-7-isopropoxyquinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-ylcarbamate (280 mg, 40.1% yield) as a beige solid.
