Procedure

(3aR,4S,6aS)-2-(4-(Trifluoromethyl)phenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-amine (120 mg, 0.359 mmol) from Step A of Example 256, iodoethane (0.287 mL, 3.59 mmol), and triethylamine (0.750 mL, 5.38 mmol) were in tetrahydrofuran (1 mL). The reaction was stirred at 65° C. for 3 days, and then the solvent was removed in vacuo. The residue was diluted with dichloromethane (5 mL), and addition of saturated aqueous sodium bicarbonate gave the products as a solid. This material was purified using a 12 g silica gel cartridge with a gradient of 0-5% methanol (2 N ammonia)/dichloromethane over 20 minutes to give two products. The second product was further purified on 4×0.25 mm preparative thin-layer chromatography plate eluting with 6% methanol (2 N ammonia)/dichloromethane to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.17-8.19 (m, 2H), 7.93-7.95 (m, 2H), 3.38 (dd, J=9.8, 3.1 Hz, 1H), 3.15 (dd, J=9.6, 3.2 Hz, 1H), 3.06 (dd, J=9.8, 8.0 Hz, 1H), 2.96 (dd, J=9.6, 7.7 Hz, 1H), 2.78 (q, J=6.1 Hz, 1H), 2.44-2.58 (m, 4H), 2.25-2.33 (m, 1H), 1.85-1.92 (m, 1H), 1.75-1.85 (m, 1H), 1.16-1.34 (m, 2H), 1.05 (t, J=7.1 Hz, 3H); MS (ESI+) m/z 363 (M+H)+.
