Versuchsvorschrift

24 ml (330 mmol) of thionyl chloride are added to a solution of 20 g (150 mmol) of 2-[ethyl-(2-hydroxy-ethyl)amino]ethanol in 200 ml of dichloromethane cooled to 0° C. The reaction medium is stirred at ambient temperature for 20 h. After addition of 50 ml of water then gradual addition of a saturated aqueous solution of sodium hydrogen carbonate up to a pH of 7, the reaction medium is extracted with dichloromethane. The organic phase is washed with water, dried over magnesium sulphate, filtered and concentrated under vacuum. 19.5 g (76%) of bis(2-chloroethyl)ethylamine are obtained in the form of a brown oil.
