Reaction Steps

To a suspension of 5-hydroxy-2-nitrobenzaldehyde (500 mg) and cesium carbonate (1.46 g) in N,N-dimethylformamide (10 mL) was added ethyl iodide (0.265 mL) at room temperature, and the mixture was stirred for 2 days. Water was added to the reaction mixture and this resulting mixture was extracted with ethyl acetate. The aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with water and saturated saline, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate-hexane) to obtain the title compound (519 mg).
