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-methyl-2-vinylbenzene (115 mg, 0.972 mmol; Aldrich) was performed according to the procedure described in Example 114B to provide 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 first-eluting enantiomer: 1H NMR (300 MHz, methanol-d4) δ ppm 1.13-1.33 (m, 3H), 1.60-1.96 (m, 4H), 2.00 (s, 3H), 2.40 (s, 3H), 2.79 (dd, J=17, 7 Hz, 1H), 2.98-3.08 (m, 1H), 3.16 (ddd, J=14, 9, 6 Hz, 1H), 3.36-3.43 (m, 1H), 4.20 (ddd, J=15, 9, 5 Hz, 1H), 4.32-4.42 (m, 2H), 6.90-6.98 (m, 2H), 6.99-7.11 (m, 3H), 7.14 (s, 1H), 7.27 (d, J=8 Hz, 1H); MS (DCI/NH3) m/z 345 (M+H)+.
