Procedure

(3aR,4S,6aS)-2-(4-(Trifluoromethyl)phenylsulfonyl)octahydrocyclopenta[c]pyrrol-4-amine (300 mg, 0.897 mmol) from Step A of Example 256 and triethylamine (0.313 mL, 2.243 mmol) were combined in dichloromethane (20 mL). 2-Nitrobenzene-1-sulfonyl chloride (258 mg, 1.166 mmol) in dichloromethane (5 mL) was added dropwise. The reaction mixture was stirred at room temperature for 16 hours. The reaction was quenched with water, and the organic layer was separated and concentrated. The resulted crude material was triturated with 50% diethyl ether/hexane, collected by filtration, washed with water then hexane to yield a solid. The crude solid was purified using a 12 g silica gel cartridge with a gradient of 10-100% ethyl acetate/hexane over 20 minutes to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 9.69 (s, 1H), 8.31 (dd, J=6.0, 3.3, 1H), 8.12 (d, J=8.2, 2H), 7.92 (dd, J=8.6, 2.1, 3H), 7.67 (dd, J=5.9, 3.3, 2H), 4.94 (s, 2H), 3.84 (dd, J=15.0, 6.2, 1H), 3.58 (dd, J=10.0, 2.4, 1H), 3.17 (dd, J=9.7, 2.7, 1H), 2.94 (dd, J=10.0, 7.7, 1H), 2.87 (dd, J=9.6, 7.7, 1H), 2.71 (td, J=9.3, 2.4, 1H), 2.60-2.50 (m, 1H), 1.94-1.80 (m, 2H), 1.71-1.58 (m, 1H), 1.23 (tt, J=10.5, 6.5, 1H); MS (ESI+) m/z 518 (M+H)+.
