A suspension mixture of (4S,5S)-2,2-dimethyl-5-((R)-1-phenylethylamino)-tetrahydro-2H-pyran-4-ol (1.0 g, 4.0 mmol) and 10% palladium on carbon (200 mg) in methanol (20 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, and the filtrate was concentrated to get the title compound (1.1 g, crude) as a yellow oil, which was used directly for the next step without further purification.
