実験手順

In a high pressure vial was added tert-butyl (3R,4S,5S)-4-azido-1-(3-(6-(2,6-difluorophenyl)-5-fluoropicolinamido)pyridin-4-yl)-5-methylpiperidin-3-ylcarbamate (1.0 equiv.), copper in charcoal (0.4 equiv.), 3-ethynyl thiophene (5.0 equiv.) and triethylamine (1.0 equiv.), in dioxane (0.09 M) to give a black suspension. The pressure tube was sealed and the mixture was stirred with heating to 100° C. overnight. The reaction was cooled to RT, filtered through celite, concentrated to yield tert-butyl (3R,4S,5S)-1-(3-(6-(2,6-difluorophenyl)-5-fluoropicolinamido)pyridin-4-yl)-5-methyl-4-(4-(thiophen-3-yl)-1H-1,2,3-triazol-1-yl)piperidin-3-ylcarbamate in 48% yield. LC/MS (m/z)=691.2 (MH+), Rt=0.98 min.
