Versuchsvorschrift

To a solution of (2S,3R)-3-azido-2-(3-chloro-2-fluoro-benzylcarbamoyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (560 mg, 1.41 mmol) in CH2Cl2 (8 mL) was added TFA (4 mL), and the solution was stirred at RT for 2 h. Methanol was added then added, and volatiles were removed under reduced pressure. The residue was taken up in methanol and concentrated in vacuo to afford the crude title compound as a yellow resin. MS (LC/MS): 298.0 [M+H]+; tR (HPLC conditions c): 3.59 min. The product was used directly in the next step without further purification.
