Procedure: A 10% palladium-carbon catalyst (about 50% wet, 114 mg) was added to a solution of (−)-(1R*,5S*)-3-benzyloxycarbonyl-1-(tert-butoxycarbonylamino)-3-azabicyclo[3.3.0]octane (569 mg, 1.579 mmol) in methanol (30 mL), and the mixture was stirred in a hydrogen atmosphere at room temperature for two hours. The catalyst was removed by filtration, and then the solvent was evaporated under reduced pressure to give crude 1-(tert-butoxycarbonylamino)-3-azabicyclo[3.3.0]octane (373 mg) as a colorless transparent gummy solid. The catalyst was removed by filtration the solvent was evaporated under reduced pressure
