Procedure
To a solution of 5H-dibenzo[a,d]cycloheptene-5-carbonitrile (described in J. Med Chem. 1994, 37, 804-810) (500mg) in DMF (10 ml) were added 60% sodium hydride (110 mg) and 1-bromo-3- chloropropane (0.30 ml) and the mixture was stirred at room temperature for 1 hours. Water and ethyl acetate were added to the reaction mixture, the organic layer was separated and washed with saturated aqueous sodium chloride, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure to give 5-(3-chloropropyl-5H-dibenzo[a,d]cycloheptene-5-carbonitrile. Without purification, to a solution obtained chloride in DMF (10 ml) were added 4-(4-chlorophenyl)-4- hydroxypiperidine (650 mg), potassium carbonate (950 mg), and potassium iodide (50 mg) and the mixture was stirred at 70° C. for 24 hours. Water and ethyl acetate were added to the reaction mixture, the organic layer was separated and washed with saturated aqueous sodium chloride, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was purified by silica gel chromatography eluting with ethyl acetate-hexane (1:1) to give the titled compound (700 mg). 1H-NMR (CDCl3) d: 1.22-1.34(2H,m), 1.60-1.80(3H,m), 1.93-1.99(2H,m), 2.16-2.28(6H,m), 2.56-2.60(2H,m), 6.98(2H,s), 7.25-7.47(10H,m), 8.00-8.03(2H,m).
