Procedure
10.0 g of 1-(2-hydroxy-5-(2-hydroxyethyl)-4-methoxyphenyl)-1-ethanone was dissolved in 100 ml of methylene chloride. Thereafter, 2.94 ml of bromine was added dropwise to the obtained solution. The obtained mixture was stirred at a room temperature for 1 hour. Thereafter, the reaction mixture was poured into ice water, and an organic layer was separated. The organic layer was successively washed with water and a saturated saline solution, and then dried over anhydrous magnesium sulfate. The solvent was then distilled away under a reduced pressure, so as to obtain 16.4 g of a yellow oil product, 2-bromo-1-(2-hydroxy-5-(2-hydroxyethyl)-4-methoxyphenyl)-1-ethanone.
