실험 절차

EDC (2.0 equiv.) and HOAt (2.0 equiv.) was added to a solution of tert-butyl (1R,2S,3S,5R)-5-(3-aminopyridin-4-yl)-2-azido-3-methylcyclohexylcarbamate (1.0 equiv.) and 6-(2,6-difluorophenyl)-5-fluoropicolinic acid (1.5 equiv.) in DMF (0.08 M). The mixture was stirred at ambient temperature overnight. The reaction mixture was diluted with water and extracted with ethyl acetate. The combined extracts were washed sequentially with 1M aqueous sodium hydroxide and brine, dried over sodium sulfate, filtered, concentrated and purified by ISCO SiO2 chromatography to yield tert-butyl (1R,2S,3S,5R)-2-azido-5-(3-(6-(2,6-difluorophenyl)-5-fluoropicolinamido)pyridin-4-yl)-3-methylcyclohexylcarbamate 59% yield. LC/MS (m/z)=582.3 (MH+), Rt=0.97 min.
