Dichloromethane → 2-Isopropoxyethyl Methanesulfonate

To a dichloromethane (50 mL) mixture of 2-isopropoxyethanol (5.21 g, 50.0 mmol) and triethylamine (7.70 mL, 55.0 mmol), was added methanesulfonyl chloride (4.30 mL, 55.0 mmol) while stirring on ice, and the resulting mixture was stirred for 30 minutes. Water and ethyl acetate were added to the mixture. After the mixture was thoroughly shaken, the organic layer was separated, and the organic layer was washed with brine and dried over anhydrous magnesium sulfate. The mixture was filtered, and the solvent in the filtrate was then distilled off under reduced pressure.
