실험 절차

3-Bromo-6-methoxycatechol (3.87 g) and diphenyl-dichloromethane (4.61 g) were heated at 170° C. with stirring without a solvent. After being allowed to stand for cooling, a saturated aqueous solution of sodium bicarbonate was added to the mixture, followed by extraction with ether. The organic layer was washed with a saturated saline and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was triturated with methanol to give Compound IIbl-a (4.7 g, 69%) as a white solid.
