N-Cyclopropyl-N-[(3aS*,4S*,6aR*)-octahydrocyclopenta[c]pyrrol-4-yl]-3-(trifluoromethyl)benzenesulfonamide from Example 201 (140 mg, 0.374 mmol) and 6,6-bis(4-fluorophenyl)hexanal (108 mg, 0.374 mmol) were combined in dichloromethane (2 mL) and then acetic acid (1 mL) was added. The reaction was stirred at room temperature for 20 minutes, then PS-cyanoborohydride (306 mg, 0.748 mmol) was added. The reaction was stirred at room temperature overnight, then filtered and the resin washed with dichloromethane. The solvent was removed in vacuo and the crude material purified using a silica gel cartridge (Analogix®, Burlington, Wis., RS-12) eluting with 1-10% methanol (2 N ammonia)/dichloromethane to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.50 (s, 1H), 8.36 (d, J=7.9, 1H), 7.95 (d, J=7.9, 1H), 7.76 (dd, J=6.4, 14.2, 1H), 7.33 (dd, J=5.6, 8.3, 4H), 7.18-7.11 (m, 4H), 3.96 (dd, J=8.0, 16.3, 2H), 3.18-3.10 (m, 1H), 2.82 (dd, J=3.5, 9.5, 1H), 2.50-2.44 (m, 2H), 2.39 (t, J=8.0, 1H), 2.31-2.21 (m, 4H), 2.03 (dd, J=7.8, 15.3, 2H), 1.91 (dt, J=3.5, 10.4, 1H), 1.59 (dt, J=5.6, 11.5, 1H), 1.51 (dd, J=10.6, 16.2, 1H), 1.46-1.33 (m, 6H), 1.28 (dd, J=7.4, 15.1, 2H), 1.08 (td, J=5.0, 10.5, 1H), 0.84 (dt, J=6.9, 12.6, 1H), 0.75-0.66 (m, 1H); MS (ESI+) m/z 647 (M+H)+.
