Reaction Steps

(3aR,4S,6aS)-2-{[2-Chloro-4-(trifluoromethyl)phenyl]sulfonyl}octahydrocyclopenta[c]pyrrol-4-amine (70 mg, 0.190 mmol) from Step B of Example 284, 2-bromo-5-(trifluoromethyl)pyridine (42.9 mg, 0.190 mmol), and triethylamine (0.079 mL, 0.569 mmol) were combined in ethanol (0.6 mL). The reaction was heated at 86° C. for 5 days and the solvent was evaporated in vacuo. The resultant material was purified using a 12 g silica gel cartridge with a gradient of 0-0.8% methanol (2 N ammonia)/dichloromethane over 20 minutes to give crude product. It was further purified by loading it onto 2×0.25 mm preparative thin-layer chromatography plate and eluted with 30% acetone/hexanes to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 8.50-8.52 (bs, 1H), 8.40 (d, J=8.2 Hz, 1H), 8.03 (s, 1H), 7.96-7.98 (m, 1H), 7.75-7.78 (m, 1H), 7.54-7.59 (m, 1H), 6.59 (d, J=8.8 Hz, 1H), 4.30-4.42 (m, 1H), 3.89 (dd, J=10.2, 2.7 Hz, 1H), 3.57 (dd, J=10.2, 7.0 Hz, 1H), 3.43 (dd, J=9.9, 6.7 Hz, 1H), 3.39 (dd, J=10.0, 2.9 Hz, 1H), 2.68 (d, J=3.5 Hz, 2H), 2.13-2.20 (m, 1H), 1.90-1.97 (m, 1H), 1.59-1.66 (m, 1H), 1.40-1.48 (m, 1H); MS (ESI+) m/z 514 (M+H)+.
