Procedure
A mixture of 6.13 g (0.021 mole) of 4-[bis(4-fluorophenyl)methyl]piperidine, 5.38 g (0.03 mole) of 2-(2-bromoethoxy)-1,3-dichlorobenzene was heated overnight at gentle reflux in 200 ml of 1-butanol. The reaction mixture was filtered and stripped to dryness. The residue was dissolved in chloroform and extracted with water and 5% sodium hydroxide solution. The oil which was obtained was chromotagraphed on 300 g of silica gel using hexane-ethyl acetate (50/50 v/v) as eluant. The fractions containing product were combined and solvent removed to furnish an oil. The oil was dried overnight in vacuo at 80° C. This furnished 5.99 g (59%) of product oil.
