Procedure

Ethyl (1R*,3S*,4R*)-4-azido-3-(tert-butoxy-carbonylamino)cyclohexane-1-carboxylate (5.4 g) was dissolved in a mixed solvent of ethanol (10 ml) and ethyl acetate (10 ml), and a catalytic amount of 10% palladium on carbon was added to stir the mixture at room temperature for 20 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 (4.7 g) as a pale yellow oil.
