Procedure

To a solution of 4-(p-anisidino)-1-[[2-(3,4,5-trimethoxyphenyl)pyridin-4-yl]methyl]piperidine (139 mg) and 3-chloromethyl-2-(3,4,5-trimethoxyphenyl)pyridine (114 mg) in acetonitrile (5 ml) was added potassium carbonate (83 mg) and potassium iodide (63 mg). The mixture was stirred at 70° C. overnight and evaporated. The residue was dissolved in chloroform, washed with water and brine, dried over anhydrous magnesium sulfate and evaporated. The residual oil was applied to a column of silica gel using diethylether-metanol (20:1) as an eluent. A free base obtained was converted to a trihydrochloride to give the title compound as yellow powder.
