Versuchsvorschrift

To a solution of 2-(2-methoxyethoxy)ethanol (300 mg, 2.5 mmol) in DCM (5 mL) was added methanesulfonyl chloride (370 mg, 2.6 mmol) dropwise at 0° C. After stirred at this temperature for 5 min, TEA (505 mg, 5.0 mmol) was added. It was stirred at room temperature overnight. The mixture was partitioned between DCM and water. The organic layers were combined, dried over sodium sulfate, filtered and concentrated to give a crude oil product, which was used without purification. Product tlc [petroleum ether/ethyl acetate [1:1) developed with iodine, Rf 0.5]
