Iodomethane (1.6 mL) was added to a DMF (15 mL) solution of (4-bromofuran-2-yl)methanol (3.0 g) as obtained in Example 18-(1). Under ice cooling, 60% sodium hydride (0.82 g) was added in divided portions, and the mixture was stirred for 1 hour and 40 minutes at room temperature. Ethyl acetate and water were added, and the organic layer was isolated. The extract was washed with water and brine sequentially, and dried over anhydrous magnesium sulfate. Then, the desiccant was filtered out, and the solvent was distilled off under reduced pressure to obtain partially purified 4-bromo-2-(methoxymethyl)furan (yellow oil) (3.9 g).
