実験手順

A solution of ethyl 2-piperidinecarboxylate (10.0 ml), 3-methoxybenzyl chloride (9.2 ml), and triethylamine (26.6 ml) in N,N-dimethylformamide (64.0 ml) was stirred at room temperature overnight and partitioned between ethyl acetate and water. The organic layer was separated, washed with water (four times) and brine, dried over MgSO4, and evaporated in vacuo. The residue was chromatographed over silica gel to afford ethyl 1-(3-methoxybenzyl)-2-piperidinecarboxylate (12.06 g) as a colorless oil.
