Procedure
A 525 mg (1.59 mmol) portion of 1-benzyl-3-(1-tert-butoxycarbonylaminocyclobutyl)pyrrolidine (fr. 2) was dissolved in 50.0 ml of ethanol, mixed with 500 mg of 10% palladium-carbon and stirred for 3 hours under a hydrogen pressure of 4 atm with warming by an infrared lamp. After removing the catalyst by filtration, the solvent was evaporated to yield quantitative amount of the title compound.
