Reaction Steps
With gentle cooling, 168.5 g of acetic anhydride are added dropwise to 133.6 g of 2-dimethylaminoethanol in the course of 20 minutes, whereupon the temperature rises from 20° C. to a maximum of 105° C. The reaction mixture is kept for 30 minutes at 100° C. and then cooled. Then 750 ml of CHCl3 are added and the acetic acid formed is neutralised with 380 ml of 20% sodium hydroxide solution at 30°-35° C. with cooling. The two phases are separated and the organic phase is washed with a small amount of H2O. Distillation of the residue affords 151.7 g (77.7%) of product with a boiling point of 114° C./225 torr.
