In a round-bottomed flask equipped with a magnetic stir bar and a reflux condenser, to a solution of trans-tert-butyl 3-azido-4-fluoropyrrolidine-1-carboxylate (45 mg, 0.195 mmol) in THF (2.5 mL) was added PPh3 on polystyrene (1.6 mmol/g, 120 mg, 0.193 mmol) and water (0.15 mL). The reaction mixture was stirred at 60° C. for 2 h. The mixture was then filtered and the filtrate dried over MgSO4 and filtered. The solvent was removed under reduced pressure to afford trans-tert-butyl 3-amino-4-fluoropyrrolidine-1-carboxylate as a pale yellow oil. LC-MS-conditions 10: tR=0.48 min; [M-CH3+H]+=190.38.
