Versuchsvorschrift

A 10% palladium carbon catalyst (50 mg) was added to a solution of (3S,4S)-1-benzyloxycarbonyl-3-(tert-butoxycarbonyl)amino-4-ethylpyrrolidine (514 mg, 1.48 mmol) in methanol (15 mL). The resultant mixture was stirred at room temperature for 2 hours under an ordinary pressure in a hydrogen atmosphere. After filtration, the filtrate was concentrated under reduced pressure, to thereby yield the title compound as a colorless oily substance (324 mg, quantitative amount).
