Versuchsvorschrift

To a solution of (+/−)-methyl 3-((1R,2R,6S)-2-(tert-butoxycarbonylamino)-6-methyl-4-(3-nitropyridin-4-yl)cyclohex-3-enyloxy)propanoate (1.0 equiv.) in degassed EtOH (0.07 M) was added Pd/C (0.3 equiv.). The mixture was purged with H2, and allowed to stir under H2 overnight at RT. The reaction was filtered through a pad of celite and the cake was washed with MeOH. The organics were concentrated and purified by ISCO SiO2 chromatography to yield (+/−)-methyl 3-((1R,2R,4R,6S)-4-(3-aminopyridin-4-yl)-2-(tert-butoxycarbonylamino)-6-methylcyclohexyloxy)propanoate in 100% yield. LC/MS (m/z)=408.2 (MH+), Rt=0.62 min.
