Reaction Steps
To a solution of methyl 5-bromo-2-(bromomethyl)furan-3-carboxylate (4.5 g) in ethanol (50 mL) was added 20% sodium ethoxide-ethanol solution (7.8 g) at 0° C., and the mixture was stirred at 0° C. for 2 hr and at room temperature overnight. The reaction was poured into water, and the mixture was acidified with 1N hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with water, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (0% ethyl acetate/hexane to 15% ethyl acetate/hexane) to give the title compound (2.8 g, 67%) as an oil.
