Reaction Conditions

Reaction Steps

In DMF (160 ml) was dissolved 5-bromosalicylaldehyde (20 g). To the mixture was added at room temperature potassium carbonate (17.9 g) and then was added 1-bromopropane (10.8 ml), and the mixture was stirred at 90° C. for 3 hours and cooled to room temperature. The reaction mixture was added to water, and the mixture was extracted with ethyl acetate, washed with saturated brine and dried with magnesium sulfate. Under reduced pressure, the solvent was evaporated, and the residue was purified with silica gel column chromatography (hexane/ethyl acetate=6/1) to give 5-bromo-2-propoxybenzaldehyde (21.9 g).
