Reaction Conditions

Reaction Steps

A solution of 4-hydroxy-3-nitrobenzaldehyde (6.9 g) and ethyl bromoacetate (5.0 mL) in dimethylformamide (250 mL) was treated with anhydrous potassium carbonate (10 g) and the mixture was heated at 60° C. for 18 hours and evaporated to dryness. The residue was partitioned between water and diethyl ether, and the diethyl ether layer was washed with 0.5M sodium hydroxide. It was then dried over anhydrous sodium sulfate and evaporated to give an oil that was chromatographed on silica gel (ethyl acetate/dichloromethane) to afford an oil (1.9 g).
