To a mixture of 2-cyclopropylethanol (5.35 g, 62.1 mmol) and dichloromethane (107 mL) were added methanesulfonyl chloride (5.29 mL, 68.3 mmol) and triethylamine (13.1 mL, 93.1 mmol) in that order while stirring on ice, and the resulting mixture was stirred for 1 hour. Water and ethyl acetate were then added to the reaction mixture. After thoroughly shaking the mixture, the organic layer was separated and the organic layer was washed with brine and dried over anhydrous magnesium sulfate. The mixture was then filtered, and the solvent in the filtrate was distilled off under reduced pressure to obtain the title compound (10.3 g, 62.7 mmol).
