Versuchsvorschrift

24 ml (330 mmol) of thionyl chloride are added dropwise to a solution of 20 g (150 mmol) of 2-[ethyl(2-hydroxyethyl)amino]ethanol in 200 ml of dichloromethane cooled beforehand to 0° C., and then the reaction medium is stirred at ambient temperature for 20 h. After the addition of a saturated aqueous solution of sodium hydrogen carbonate, the product is extracted with dichloromethane. The organic phase obtained is then washed with water, dried over magnesium sulfate, filtered and concentrated under vacuum. 19.5 g (76%) of bis(2-chloroethyl)ethylamine are obtained in the form of an oil.
