실험 절차
To a solution of 4-bromo-2-chlorobenzyl alcohol (3.56 g) and anhydrous triethylamine (3 ml) in anhydrous dichloromethane (36 ml) was dropwise added methanesulfonyl chloride (1.4 ml) under a nitrogen atmosphere and ice-cooling. The reaction mixture was stirred for 1 hr, washed with water, a saturated aqueous sodium hydrogencarbonate solution and saturated brine, and dried over anhydrous magnesium sulfate. The filtrate was concentrated to give the objective compound (4.77 g) as a light brown solid.
