Versuchsvorschrift

A mixture of tert-butyl 3-hydroxy-3-phenylpyrrolidine-1-carboxylate (0.36 g, 0.0014 mol) and trifluoroacetic acid (2.0 mL, 0.026 mol) was stirred under nitrogen at room temp for 1 h. The volatile was removed under vacuum and evaporated with toluene twice. The residue was used in next step w/o further purification. LCMS: 146.1 (M+H)+.
