Versuchsvorschrift

To a solution of ((S)-5-tert-butoxycarbonylamino-6-{(S)-2-[5-(4-fluoro-benzoyl)-pyridin-3-yl]-pyrrolidin-1-yl}-6-oxo-hexyl)-carbamic acid 9H-fluoren-9-ylmethyl ester (I-1a) in dichloromethane (15 mL) was added trifluoroacetic acid (5 mL). After stirring for 45 minutes, the reaction mixture was concentrated in vacuo to afford crude ((S)-5-amino-6-{(S)-2-[5-(4-fluoro-benzoyl)-pyridin-3-yl]pyrrolidin-1-yl}-6-oxo-hexyl)-carbamic acid 9H-fluoren-9-ylmethyl ester as a dark amber residue.
