Versuchsvorschrift

To a solution of 2-cyclopropylethanol (2.1 g, 24.4 mmol) in dichloromethane (50 ml) at 0° C. under nitrogen was added triethylamine (4.1 ml, 1.3 mol equiv). Methanesulphonyl chloride (2.5 ml, 1.3 mol equiv) was added dropwise and the reaction stirred for 16 hours at room temperature. Water (30 ml) and dichloromethane (30 ml) were added. The organic phase was washed with water (2×50 ml) and then dried over anhydrous MgSO4. The solution was then filtered and the solvent removed in vacuo to give the title compound as an oil (4.0 g).
