Reaction Steps
A solution of ethyl benzyl-3-(tert-butoxycarbonylamino)-3-(fluoromethyl)pyrrolidine-1-carboxylate (2.27 g, 6.44 mmol) and ammonium formate (3.03 g, 32.2 mmol) in ethanol (60 mL) was flushed with nitrogen for 15 minutes. 10% Pd/C (0.69 g, 0.644 mmol) was added and the mixture heated at reflux for 30 minutes. The reaction mixture was cooled to ambient temperature, filtered through a pad of Celite and washed with ethanol (30 mL) and concentrated under reduced pressure to afford tert-butyl 3-(fluoromethyl)pyrrolidin-3-ylcarbamate (1.4 g, 100%).
