反応手順
A solution of N-[3-({2-({6-[(5R)-5-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-2-oxo-1,3-oxazolidin-3-yl]hexyl}oxy)ethoxy}methyl)phenyl]-N′-(3-nitrophenyl)urea (0.976 g) in EtOH (12 ml) and EtOAc (12 ml) was hydrogenated over platinum oxide (0.020 g) for 2 h. The mixture was filtered through celite and washed with EtOH. Solvent evaporation in vacuo gave the title compound (0.93 g). LCMS RT=3.48 min, ES+ve 633 (MH)+.
