The tert-butyl (S)-1-azido-3-((R)-tetrahydro-2H-pyran-3-yl)propan-2-yl(methyl)carbamate (2.1 g, 7.04 mmol, 1.0 equiv) and Pd/C (10%, 200 mg) were added to a flask. THF (30 mL) was added and the flask fitted with a gas inlet connected to a balloon of hydrogen gas. The flask was evacuated and back-filled with H2 from the balloon. This was repeated twice and the reaction mixture stirred for 17 h at ambient temperature. Analysis by LC/MS showed complete conversion to the desired amine. The catalyst was removed by filtration through a pad of Celite and the mixture evaporated. This provided 1.82 g (94%) of tert-butyl (S)-1-amino-3-((R)-tetrahydro-2H-pyran-3-yl)propan-2-yl(methyl)carbamate.
