Procedure

A 10% palladium carbon catalyst (50 mg) was added to a solution of (3S,4S)-1-benzyloxycarbonyl-3-(tert-butoxycarbonyl)amino-4-cyclopropylpyrrolidine (408 mg, 1.13 mmol) in ethanol (5 mL), followed by stirring in a hydrogen atmosphere under an ordinary pressure at 45° C. for 12 hours. After filtration, the filtrate was concentrated under reduced pressure, to thereby yield the title compound as a colorless oily substance (255 mg, quantitative amount). The product was employed, without further purification, in the subsequent step.
