実験手順

A mixture of 4-(3-Methoxy-phenyl)-piperidine (0.8 g, 4.2 mmol), methylbromoacetate (1.28 g, 8.38 mmol), diisopropylethylamine (3.7 mL, 21 mmol) and MeOH (40 mL) was refluxed for 3 h. The reaction mixture was concentrated in vacuo, and the residue was partitioned between water and EtOAc and extracted. The organic layer was washed with water, brine, dried and concentrated in vacuo to give the title compound as an oil (1.0 g, 91% yield). MS(ESI) 264.2 (M+H+)
