(3aS*,4S*,6aR*)-2-Benzyl-N-cyclopropyloctahydrocyclopenta[c]pyrrol-4-amine (382 mg, 1.490 mmol) from Example 198, triethylamine (312 μL, 2.235 mmol), and 3-(trifluoromethyl)benzene-1-sulfonyl chloride (262 μL, 1.639 mmol) were combined in tetrahydrofuran (7 mL). A catalytic amount of (dimethylamino)pyridine was added, and the reaction mixture was stirred at room temperature overnight. The solvent was reduced in volume, and the crude material applied to silica gel and eluted with 20% to 100% ethyl acetate/hexanes to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.46 (s, 1H), 8.31 (d, J=7.9, 1H), 7.93 (d, J=7.8, 1H), 7.74 (t, J=7.9, 1H), 7.41 (d, J=7.2, 2H), 7.36 (t, J=7.4, 2H), 7.29 (t, J=7.2, 1H), 3.97 (ddd, J=6.1, 7.7, 13.5, 1H), 3.54-3.45 (m, 2H), 3.17 (dt, J=5.9, 11.8, 1H), 2.82 (dd, J=3.6, 9.7, 1H), 2.55 (t, J=8.2, 1H), 2.51-2.43 (m, 2H), 2.36-2.22 (m, 2H), 1.88-1.82 (m, 1H), 1.57 (dt, J=5.9, 11.6, 1H), 1.43-1.32 (m, 3H), 1.05-0.98 (m, 1H), 0.80 (ddd, J=6.9, 9.8, 12.4, 1H), 0.73-0.65 (m, 1H); MS (ESI+) m/z 465 (M+H)+.
