実験手順

(3aS*,6aR*)-2-Benzyloctahydrocyclopenta[c]pyrrol-4-amine (500 mg, 2.311 mmol), 2,2-dicyclohexylacetic acid (570 mg, 2.54 mmol), and 1-hydroxybenzotriazole (389 mg, 2.54 mmol) were combined in dichloromethane (20 mL). The reaction was stirred at room temperature for 10 minutes, then N-(3-dimethylaminopropyl)-N-ethylcarbodiimide (0.449 mL, 2.54 mmol) was added dropwise. The reaction was stirred at room temperature for 20 hours, and then the reaction was quenched with 10 mL of water. The reaction was extracted with 2×20 mL of dichloromethane, the solvent was removed in vacuo, and the crude material was chromatographed over a silica gel cartridge (Analogix®, Burlington, Wis., RS-40) eluting with 30-50% ethyl acetate/hexanes to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 7.60 (d, J=5.1, 1H), 7.45-7.38 (m, 4H), 7.35 (m, 1H), 4.49-4.41 (m, 1H), 3.57 (d, J=12.6, 1H), 3.37 (d, J=12.5, 1H), 2.76 (d, J=9.6, 1H), 2.69 (dd, J=7.9, 15.7, 1H), 2.50 (d, J=9.1, 1H), 2.48-2.41 (m, 1H), 2.28 (t, J=8.2, 1H), 2.15-2.08 (m, 1H), 1.99-1.06 (m, 26H), 1.04-0.92 (m, 1H); MS (ESI+) m/z 423 (M+H)+.
