The reaction solution was cooled to room temperature and water was added thereto, followed by extracting the resulting mixture with ethyl acetate. Organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. After removing anhydrous sodium sulfate by filtration, the filtrate was concentrated. The residue was purified by column chromatography (silica gel, eluent: hexane/ethyl acetate=5/1) to obtain 2-(4-iodophenoxy)-4-methoxypyrimidine (312 mg).
