Procedure

To a solution of 3-hydroxybenzaldehyde (10.0 g) and ethyl bromoacetate (15.0 g) in DMF (150 mL) was added potassium carbonate (17.0 g), and the mixture was stirred at 60° C. for 15 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (16.7 g) as a colorless oil.
