Versuchsvorschrift
A mixture of trans-1-benzyl-3-(difluoromethyl)-4-nitropyrrolidine (25 g, 0.097 mol) and Pd (OH)2/C (4 g) in MeOH (200 mL) was placed under a hydrogen atmosphere (50 psi) at rt overnight. The mixture was filtered to yield trans-4-(difluoromethyl)pyrrolidin-3-amine in solution. Boc2O was added at 0° C. and the resulting mixture was stirred at 0° C. for 4 hrs, then concentrated and purified by column chromatography (100% EtOAc) to give the title compound (14 g, 61% yield) as a yellow oil.
