A suspension of 4-butyl-5-methyl-1H-pyrrole-3-carbonitrile (0.081 g), 4-fluoro-benzoic acid ethyl ester (0.10 g) and cesium carbonate (0.21 g) in N,N-dimethylformamide (3 mL) was stirred at 70° C. overnight. This reaction mixture was poured into water, and this mixture was extracted with ethyl acetate. This organic layer was washed with brine, dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: ethyl acetate/n-hexane=1/6) to give the title compound (0.032 g).
