Participants

Reaction Steps

The title compound was prepared by combining 5-fluoro-1H-indole-2-carbaldehyde (30.1 mg, 0.184 mmol) and (3aR,4S,6aS)-2-(5-(trifluoromethyl)pyridin-2-yl)octahydrocyclopenta[c]pyrrol-4-amine (50 mg, 0.184 mmol) from Example 262 Step B in dichloromethane (0.2 mL) to give a colorless solution. 0.2 mL of acetic acid was added. The reaction was stirred at ambient temperature for 30 minutes, then PS-cyanoborohydride (166 mg, 0.369 mmol) was added. After 18 hours, the reaction was filtered and the solvent was removed in vacuo. The crude material was purified using a 12 g silica gel cartridge eluted with 1-10% methanol (2 N ammonia)/dichloromethane to give the title compound: 1H NMR (500 MHz, pyridine-d5) δ ppm 12.14 (s, 1H), 8.64 (dd, J=1.5, 0.7, 1H), 7.69 (dd, J=8.9, 2.5, 1H), 7.54-7.46 (m, 2H), 7.14-7.07 (m, 1H), 6.61 (d, J=1.2, 1H), 6.36 (d, J=8.9, 1H), 4.12-4.00 (m, 2H), 3.56 (ddd, J=21.0, 9.4, 3.4, 2H), 3.48-3.40 (m, 1H), 3.28 (ddd, J=3.7, 2.1, 0.9, 1H), 3.04 (dd, J=11.0, 5.8, 1H), 2.78-2.68 (m, 1H), 2.57-2.50 (m, 1H), 2.31-2.04 (m, 1H), 2.02-1.91 (m, 2H), 1.55-1.44 (m, 1H), 1.38-1.28 (m, 1H); MS (ESI+) m/z 419 (M+H)+.
