Reaktionsschritte

A suspension of 3-cyanoindole (0.14 g), 5-bromo-2-furaldehyde (0.18 g), and cesium carbonate (0.39 g) in N,N-dimethylformamide (3 mL) was stirred at room temperature or 3 hours. This reaction mixture was heated at 50° C., stirred for 2 hours. After cooling to ambient, water was added to this reaction mixture. This mixture was extracted with ethyl acetate, and this organic layer was washed with brine, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate-2/1) to give the title compound (0.086 g).
