Degass a solution of (+/−)-(1S,2R,6S)-2-((tert-butoxycarbonyl)amino)-6-methyl-4-(3-nitropyridin-4-yl)cyclohex-3-en-1-yl methanesulfonate (1.0 equiv.) in Ethanol (0.20 M). To this solution was added Pd/C (0.2 equiv.) and purge with Ar and H2. The mixture was stirred under H2 for 16 hrs. Filter the mixture over cetlite and wash the cake with MeOH. Concentrate the filtrate to yield (+/−)-(1S,2R,4R,6S)-4-(3-aminopyridin-4-yl)-2-((tert-butoxycarbonyl)amino)-6-methylcyclohexyl methanesulfonate in 49% yield). LC/MS (m/z)=400.3 (MH+), Rt=0.62 min.
