Reaction Conditions

Reaction Steps

Sodium hydride (60% oil, 3.99 g) was added to a DMF (100 mL) solution of ethyl 3,5-dihydroxy-4-iodobenzoate (15.0 g), and the mixture was stirred at 0° C. for 30 minutes in a nitrogen atmosphere. Iodoethane (4.09 mL) was added to the reaction mixture, and the mixture was stirred at room temperature for 2 hours. Water was added to the reaction mixture, followed by extraction with ethyl acetate. The obtained organic layer was washed with saturated saline and dried over anhydrous magnesium sulfate, and then, the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to obtain the title compound (7.59 g).
