A solution of 4-(2-Chloro-phenyl)-4-methyl-piperidine (0.29 g, 1.38 mmol) in isopropanol (5 mL) was treated with 2-[5-(3-Bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.19 g, 0.50 mmol) and catalytic potassium iodide. The solution was stirred at 80° C. for 12 hr, and evaporated in vacuo. The residue was purified by silica gel chromatography (ethyl acetate→87:10:3 ethyl acetate/methanol/triethylamine) to yield 0.062 g (25%) of the title compound, 1H-NMR (CDCl3) ∂: 1.10 (3H, s), 1.58 (6H, s), 1.78 (2H, m), 1.90 (1H, m), 2.10 (2H, m), 2.40 (8H, m), 5.30 (2H, brs), 6.18 (1H, t), 6.79 (1H, m), 6.92 (1H, m), 7.19-7.39 (6H, m), 7.42 (1H, m), 7.55 (1H, m), 8.55 (1H, d). ESI-MS m/z: 503 [M+1].
