Procedure

To tert-butyl (S)-1-((R)-2,2,2-trifluoro-1-(6-((E)-2-((6-fluoro-8-methoxyquinolin-2-yl)methylene)hydrazinyl)pyridin-3-yl)ethyl)pyrrolidin-3-ylcarbamate (300 mg, 0.533 mmol) in DCM (5 mL) was added iodosobenzene diacetate (206 mg, 0.640 mmol) and the reaction was stirred at ambient temperature for 2 hours. After concentration, the residue was purified by reverse phase chromatography (SP4, 12M, eluting with a gradient of water/ACN 100:0 to 0:100, 20 column volumes) to yield tert-butyl (S)-1-((R)-2,2,2-trifluoro-1-(3-(6-fluoro-8-methoxyquinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-ylcarbamate (189 mg, 63.2% yield) as a beige solid
