실험 절차

1,4-Difluoro-2-nitrobenzene 239 mg, ethyl 3-(1H-imidazol-2-yl)propanoate 252 mg, potassium carbonate 415 mg and N,N-dimethylacetamide 10 mL were heated at 100° C. for 64 hours. The reaction liquid was diluted with ethyl acetate and filtered. The filtrate was condensed under reduced pressure and subjected to silica gel chromatography (ethyl acetate) to provide 220 mg of the title compound.
