실험 절차

To a mixture of ethyl 4-iodobenzoate (1.5 mL), oxazolidin-2-one (940 mg), potassium carbonate (2.5 g) and copper (I) iodide (171 mg) were added toluene (9 mL) and N,N′-dimethylethylenediamine (195 μL), and the mixture was refluxed for 8 hr. After cooling, water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated. The residue was purified by column chromatography (chloroform) to give the title compound (1.2 g).
