Benzyl{(2R,3S)-3-hydroxy-4-[(tripropan-2-ylsilyl)oxy]butan-2-yl}carbamate (3.70 g, 9.35 mmol) synthesized in Example (89d) was dissolved in ethanol (30 mL), and palladium carbon (1.00 g) was added, followed by stirring at room temperature for 8 hours under hydrogen atmosphere. After Celite filtration, the solvent was distilled off under reduced pressure to afford the desired compound (2.65 g, yield ˜100%) as a pale yellow liquid.
