실험 절차
In 100 mL of methylene chloride was dissolved 10.0 g of 1-[2-hydroxy-5-(2-hydroxyethyl)-4-methoxyphenyl]-1-ethanone, and 2.94 mL of bromine was added dropwise to the solution, after which the resulting mixture was stirred at room temperature for 1 hour. The reaction mixture was poured into ice water and the organic layer was separated. The organic layer was washed with water and then a saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to obtain 16.4 g of 2-bromo-1-[2-hydroxy-5-(2-hydroxyethyl)-4-methoxyphenyl]-1-ethanone as a yellow oil.
