Reaction Steps

After dissolving 139 mg of (E)-4-[2-(3-methyl-2-thienyl)vinyl]piperidine in 7 ml of tetrahydrofuran, 111 mg of 3-methoxypyrazine-2-carboxaldehyde and 213 mg of sodium triacetoxyborohydride were added while stirring, and the stirring was continued overnight at room temperature. A 1N sodium hydroxide solution was added to the reaction mixture to render it alkaline, and then extraction was performed with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue was purified by NH silica gel column chromatography (solvent: n-hexane/ethyl acetate) to obtain the title compound (120 mg, 54% yield).
