Reaction Steps

To an ice-cooled solution of 4-[N-methyl-N-[[2-(3,4,5-trimethoxyphenyl)pyridin-4-yl]methyl]amino]-1-[[2-(3,4,5-trimethoxyphenyl)pyridin-4-yl]methyl]piperidine (100 mg) in dichloromethane (5 mL) was added iodotrimethylsilane (173 μL). The mixture was stirred at 0° C. for 2 hours and then at room temperature overnight. A small amount of water, ethyl acetate and saturated aqueous sodium hydrogencarbonate were added to the mixture at 0° C. and the organic layer was separated. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and evaporated. The residue was applied to a preparative TLC using chloroform-ammonia saturated methanol (15:1) to give a free base of the title compound which was converted to a tetrahydrochloride by the conventional method.
