Reaction Steps
To a mixture of ethyl 4-iodobenzoate (552 mg), 4-methylpyrrolidin-2-one (198 mg), potassium carbonate (536 mg) and copper(I) iodide (190 mg) were added toluene (2 mL) and N,N′-dimethylethylenediamine (215 μL), and the mixture was stirred with heating under reflux for 8 hr. The reaction mixture was cooled, water was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated. The obtained residue was purified by column chromatography (hexane:ethyl acetate) to give the title compound (377 mg).
