Procedure

2,2-Dicyclohexyl-N-((3aS,4S,6aR)-octahydrocyclopenta[c]pyrrol-4-yl)acetamide from Example 53 (101 mg, 0.304 mmol), triethylamine (0.042 mL, 0.304 mmol), and 3-(trifluoromethyl)benzene-1-sulfonyl chloride (0.049 mL, 0.304 mmol) were combined in dichloromethane (2 mL). A catalytic amount of N,N-dimethylaminopyridine was added. The reaction was stirred at room temperature for 1 hour, LCMS showed product, and TLC showed no more starting material. The reaction was quenched with aqueous sodium bicarbonate and the aqueous layer was separated. The organic layers was concentrated to give a precipitate. The precipitate was washed with water and ether and dried under a stream of nitrogen to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.49 (d, J=6.3, 1H), 8.34 (s, 1H), 8.19 (d, J=7.9, 1H), 7.93 (d, J=7.8, 1H), 7.73 (t, J=7.8, 1H), 4.46-4.38 (m, 1H), 3.73 (dd, J=3.4, 9.3, 1H), 3.17 (dd, J=2.8, 9.7, 1H), 3.07 (ddd, J=6.4, 12.0, 23.6, 3H), 2.49 (dd, J=8.0, 15.9, 1H), 2.12 (t, J=7.2, 1H), 2.02-1.77 (m, 8H), 1.73 (dd, J=5.3, 9.0, 4H), 1.68-1.58 (m, 3H), 1.52 (ddd, J=3.2, 12.5, 14.7, 1H), 1.43 (ddd, J=3.1, 12.6, 15.0, 1H), 1.37-1.03 (m, 9H); MS (ESI+) m/z 541 (M+H)+.
