Reaction Steps

The coupling of 2-methyl-6,7,8,9,10,11-hexahydro-5H-7,11-epiminocycloocta[b]indole (110 mg, 0.486 mmol; Example 118A) and 1,4-dimethyl-2-vinylbenzene (129 mg, 0.972 mmol; Aldrich) was performed according to the procedure described in Example 114B to afford the title compound as a racemic mixture. Individual enantiomers were obtained by preparative chiral supercritical fluid chromatography (ChiralPak® OD-H 5 μm column, 21×250 mm, 35° C., 10-50% gradient of CH3OH—CO2 containing 0.1% diethylamine, 20 minutes) to afford the title compound as the second-eluting enantiomer: 1H NMR (300 MHz, methanol-d4) δ ppm 1.07-1.32 (m, 3H), 1.62 (dd, J=13, 2 Hz, 1H), 1.70-1.95 (m, 3H), 2.00 (s, 3H), 2.15 (s, 3H), 2.40 (s, 3H), 2.79 (dd, J=17, 7 Hz, 1H), 2.94-3.16 (m, 2H), 3.34-3.40 (m, 1H), 4.19 (ddd, J=14, 9, 5 Hz, 1H), 4.28-4.39 (m, 2H), 6.69 (s, 1H), 6.85-6.97 (m, 3H), 7.13 (s, 1H), 7.26 (d, J=8 Hz, 1H); MS (DCI/NH3) m/z 359 (M+H)+.
