Add 4-(4-fluoro-phenyl)-piperidine (133 mg, 0.744 mol) (See Table No.1, SM 2) to a suspension of 3-[4-(2-bromo-ethoxy)-phenyl]-6-fluoro-benzo[d]isoxazole (250 mg, 0.744 mol) in a mixture of water:acetonitrile (0.1 mL:2.5 mL). Then add potassium carbonate (164 mg, 1.63 mmol) and potassium iodide (12 mg, 1.07 mmol) and heat at reflux for 8 hours. Stir at room temperature for 72 hours, filter the suspension and wash the solid thoroughly with dichloromethane. Dilute the resulting solution with dichloromethane (5 mL) and wash with water (5 mL), 10% HCl (5 mL), water (5 mL), saturated sodium chloride (5 mL), dry (MgSO4), filter and evaporate to give a white solid. Dissolve the solid in a minimum amount of chloroform and add 1.0 M HCl in ether and stir under a nitrogen atmosphere for 1 hour. Collect the solid by vacuum filtration, wash thoroughly with ether and dry to give the title compound (168 mg, 48% Yield). Microanalysis (C, H, N) is consistent with the final, desired compound. mp-235-239° C.
