Procedure

A mixture of tert-butyl (S)-3-methyl-1-((S)-2,2,2-trifluoro-1-(6-hydrazinylpyridin-3-yl)ethyl)pyrrolidin-3-ylcarbamate (53 mg, 0.14 mmol), 7-(2-methoxyethoxy)quinoline-2-carbaldehyde (30 mg, 0.13 mmol) and EtOH (1.4 mL) was stirred at ambient temperature overnight. The solvent was removed under reduced pressure. The residue was dissolved in DCM (1.4 mL) and iodosobenzene diacetate (54 mg, 0.17 mmol) was added. The reaction mixture was stirred at ambient temperature overnight and then loaded to a silica gel column eluting with 1:2 to 3:1 EtOAc/hexanes to give tert-butyl (S)-3-methyl-1-((S)-2,2,2-trifluoro-1-(3-(7-(2-methoxyethoxy)quinolin-2-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yl)ethyl)pyrrolidin-3-ylcarbamate (72 mg, 92%).
