Procedure

To tert-butyl (S)-1-((R)-2,2,2-trifluoro-1-(6-((E)-2-((6-fluoro-8-isopropoxyquinolin-2-yl)methylene)hydrazinyl)pyridin-3-yl)ethyl)pyrrolidin-3-ylcarbamate (157 mg, 0.266 mmol) in DCM (10 mL) was added iodosobenzene diacetate (94.2 mg, 0.292 mmol) and the reaction was stirred at ambient temperature for 2 hours. The reaction was concentrated to dryness and the residue 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-isopropoxyquinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-ylcarbamate (124 mg, 79.3% yield) as a beige solid.
