Procedure

To a solution of ethyl piperidine-4-carboxylate (514 mg) and 4-chloromethyl-2-(3,4,5-trimethoxyphenyl)pyridine (969 mg) in acetonitrile (20 mL) was added potassium carbonate (452 mg). The mixture was stirred at room temperature for 4 hours and evaporated. The residual oil was subjected to a column of silica gel and eluted using hexane-ethyl acetate (2:1) and then chloroform-methanol (40:1). Fractions containing the product were collected and evaporated to give the title compound as white prisms.
