Vorschrift

To a solution of (3S)-3-(tert-butoxycarbonylamino)-3-fluoromethyl-4-methyl-1-[(1R)-1-phenylethyl]pyrrolidine (200 mg, 0.594 mmol) in ethanol (12 mL) was added 10% palladium-carbon catalyst (containing 52.8% water, 200 mg), and the suspension was stirred in an oil bath at 40° C. for 2 hours in hydrogen gas atmosphere. After removing the catalyst by filtration, the solvent was removed by distillation under reduced pressure to obtain 150 mg (quantitative) of the crude title compound as a white solid.
