Procedure
A mixture of 2-(trimethylsilyl)ethyl (3S,4S)-4-azido-6,6-dimethyl-tetrahydro-2H-pyran-3-ylcarbamate (510 mg, 1.25 mmol), 10% palladium on carbon (50 mg) in methanol (10 mL) was stirred at room temperature under 1 atm hydrogen atmosphere (hydrogen balloon) overnight. After that, the mixture was filtered through a pad of celite. The filtrate was concentrated to get the title compound (450 mg, crude) as a brown oil, which was used directly for the next step without further purification.
