Reaction Steps
(3aR,4S,6aS)-2-(3-(Trifluoromethyl)benzyl)octahydrocyclopenta[c]pyrrol-4-amine (60 mg, 0.211 mmol), from Example 156 Step A was combined with (bromomethylene)dibenzene (62.6 mg, 0.253 mmol) and potassium carbonate (87 mg, 0.633 mmol) in N,N-dimethylformamide (1 mL). The reaction was stirred at room temperature for 72 hours. The reaction was quenched with water and extracted with diethyl ether. The ether extracts were washed with water (3×1 mL) and the solvent removed. The crude material was purified using a 12 g silica gel cartridge eluting with a gradient of 0-3% methanol (2 N ammonia)/dichloromethane to give (3aR,4S,6aS)-N-benzhydryl-2-(3-(trifluoromethyl)benzyl)octahydrocyclopenta[c]pyrrol-4-amine: 1H NMR (500 MHz, pyridine-d5) δ ppm 7.71 (s, 1H), 7.64-7.59 (m, 4H), 7.52 (d, J=7.7, 1H), 7.44 (t, J=7.7, 1H), 7.33 (td, J=7.6, 4.7, 4H), 7.25-7.21 (m, 4H), 5.09 (s, 1H), 3.51 (q, J=13.5, 2H), 3.02 (dd, J=12.9, 5.5, 1H), 2.63-2.54 (m, 1H), 2.51 (dd, J=8.8, 2.8, 1H), 2.47-2.41 (m, 1H), 2.37 (t, J=8.0, 1H), 2.32-2.25 (m, 2H), 1.98 (td, J=11.4, 5.6, 1H), 1.89 (ddd, J=12.7, 10.4, 5.8, 1H), 1.45 (ddd, J=14.7, 11.9, 8.1, 1H), 1.32-1.23 (m, 1H); MS (ESI+) m/z 451 (M+H)+.
