Procedure

tert-Butyl(S)-1-((3aR,4S,6aS)-2-(4-fluorophenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-ylamino)-4,4-dimethyl-1-oxopentan-2-ylcarbamate was prepared by substituting (S)-2-(tert-butoxycarbonylamino)-4,4-dimethylpentanoic acid for N-(tert-butoxycarbonyl)-L-leucine and (3aR,4S,6aS)-2-(4-fluorophenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-amine from Example 261 Step A for (3aR,4S,6aS)-2-benzyloctahydrocyclopenta[c]pyrrol-4-amine in the procedure described in Example 221: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.70 (d, J=7.0, 1H), 8.14 (d, J=8.7, 1H), 7.99 (dd, J=8.6, 5.2, 2H), 7.32 (t, J=8.6, 2H), 4.75-4.65 (m, 1H), 4.27-4.18 (m, 1H), 3.74 (dd, J=9.9, 2.7, 1H), 3.10 (ddd, J=13.9, 9.6, 5.4, 2H), 2.92 (dd, J=9.4, 7.7, 1H), 2.61-2.47 (m, 2H), 2.15 (dd, J=14.2, 4.7, 1H), 1.89-1.73 (m, 3H), 1.56-1.45 (m, 10H), 1.28-1.18 (m, 1H), 0.98 (s, 9H); MS (ESI+) m/z 512 (M+H)+.
