Reaction Steps
Ethyl 5-phenyl-1H-pyrrole-2-carboxylate (400 mg) and 4-methoxybutyl methanesulfonate (440 mg) were dissolved in DMF (10 ml), cesium carbonate (780 mg) was added and the mixture was stirred at 60° C. for 12 hr. The reaction mixture was poured into water and the mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate-hexane (1:9-1:4) was concentrated under reduced pressure to give the object product (430 mg).
