Reaktionsschritte
To a degassed a solution of (+/−)-tert-butyl ((1R,2S,3S,5R)-5-(3-((tert-butoxycarbonyl)amino)pyridin-4-yl)-2-azido-3-methylcyclohexyl)carbamate (1.0 equiv.) in ethanol (0.10 M) was added Pd/C (0.2 equiv.). The mixture was stirred under H2 for 4 hrs. Filter the mixture over cetlite and wash the cake with MeOH. Concentrate the filtrate to yield (+/−)-tert-butyl ((1R,2S,3S,5R)-5-(3-((tert-butoxycarbonyl)amino)pyridin-4-yl)-2-amino-3-methylcyclohexyl)carbamate in 88% yield. LC/MS (m/z)=421.3 (MH+), Rt=0.58 min.
