Procedure
Ethyl (1S,3R,4S)-4-azido-3-(tert-butoxy-carbonylamino)cyclohexane-1-carboxylate (4.0 g) was dissolved in a mixed solvent of ethanol (150 ml) and ethyl acetate (150 ml), and 5% palladium on carbon (0.5 g) was added to stir the mixture at room temperature for 17 hours in a hydrogen atmosphere. After insoluble matter was removed by filtration, the solvent was distilled off under reduced pressure to obtain the title compound (4.2 g) as a pale yellow oil.
