Procedure

A suspension of [((1S,2S,4R)-4-azido-2-{[tert-butyl(dimethyl)silyl]oxy}-cyclopentyl)methoxy](tert-butyl)dimethylsilane (2.13 g, 0.00552 mol) and 10% Pd/C (0.27 g, 0.00026 mol) in EtOAc (45.0 mL, 0.461 mol) was stirred under an atmosphere of hydrogen overnight. The reaction was purged with nitrogen and filtered the mixture through celite with EtOAc. The filtrate was concentrated to obtain 1.83 g (92.1%) of the title compound.
