Procedure
To an aqueous solution (15 mL) of imidazole (5.69 g), 3-bromo-4-methoxybenzaldehyde (3.00 g) and copper powder (86 mg) were added, and the reaction solution was agitated for three days at 100° C. under nitrogen atmosphere. A concentrated ammonia water and ethyl acetate were added to the reaction mixture, and the organic layer was partitioned. The organic layer was washed with a saturated saline solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent:ethyl acetate), and 321 mg of the title compound was obtained.
