Reaction Steps
To a suspension of sodium hydride (843 mg) in THF (5 mL) was added methanol (675 mg) under ice-cooling, and the mixture was stirred at room temperature for 0.5 hour. 3-Bromo-5-ethoxy-4-hydroxybenzaldehyde (1.29 g) in dimethylformamide (10 mL), and copper(I) chloride (31 mg) were added thereto, and the mixture was stirred at 120° C. for 4 hours under heating. The mixture was allowed to stand for cooling down to room temperature, diluted with ethyl acetate, washed with 1N hydrochloric acid, dried over anhydrous sodium sulfate, and then concentrated. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate=2:1, v/v) to give the title compound (630 mg).
