Procedure

{(3S,5S)-1-{(S)-2-[(S)-2-(tert-Butoxycarbonyl-methyl-amino)-propionylamino]-2-cyclohexyl-acetyl}-5-[(R)-(1,2,3,4-tetrahydro-naphthalen-1-yl)carbamoyl]-pyrrolidin-3-yl}-carbamic acid 9H-fluoren-9-ylmethyl ester (Intermediate 25) (100 mg, 124 μM) was dissolved in DMF (0.9 mL) at room temperature and piperidine (0.1 mL) was added. The mixture was stirred at room temperature for 30 minutes, concentrated and the residue purified by chromatography over silica gel to give the title compound as white foam (56.7 mg, 78%). LC-MS: 585 (M+H).
