Procedure
(3aS*,4S*,6aR*)-2-(3-(Trifluoromethyl)benzyl)octahydrocyclopenta[c]pyrrol-4-amine (228 mg, 0.802 mmol) from Example 122 Step E and (1-ethoxycyclopropoxy)trimethylsilane (140 mg, 0.802 mmol) were combined in dichloromethane (1.5 mL) and 5 mL of acetic acid was added. The reaction was stirred at room temperature for 20 minutes, and then PS-cyanoborohydride (343 mg, 0.802 mmol) was added. The reaction was heated to 40° C. overnight. Silica gel chromatography eluting with 1-10% methanol (2 N ammonia)/dichloromethane to gave the title compound: 1H NMR (300 MHz, CDCl3) δ ppm 7.58 (s, 1H), 7.48 (d, J=7.6, 2H), 7.42 (d, J=7.6, 1H), 3.64 (d, J=13.6, 1H), 3.51 (d, J=13.6, 1H), 2.94-2.82 (m, 3H), 2.80-2.71 (m, 2H), 2.55 (dd, J=5.4, 9.4, 3H), 2.41 (t, J=8.3, 1H), 2.16 (dd, J=4.7, 8.7, 1H), 1.97-1.70 (m, 7H), 1.70-1.59 (m, 3H), 1.40 (dd, J=6.7, 12.6, 1H); MS (ESI+) m/z 365 (M+H)+.
