4-(4-Chloro-phenyl)-4-methoxy-piperidine (0.072 g, 0.319 mmol) was dissolved in isopropanol (5 mL) and 2,6-lutidine (0.034 g, 37 uL, 0.319 mmol) was added. Catalytic iodine was also added. The resulting suspension was warmed to 80° C. Solid 2-[5-(3-Bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.060 g, 0.160 mmol) was added in approximately equal portions over 2 h. Stirring was continued an additional 20 h at 80° C. The mixture was concentrated and the resulting residue purified by silica gel chromatography (ethyl acetate to 87/10/3 ethyl acetate/methanol/triethylamine gradient) to afford the title compound (70 mg, 42%).
