Participants

Reaction Steps

A 50 ml 3 neck round bottom flask was fitted with the following: magnetic stirrer, reflux condenser, air bubbler, and a temperature controlled oil bath. The flask was charged with 19.0 g of 2-{[2-(2-dimethylamino ethoxy)ethyl]methylamino}ethanol. Sodium hydride, 0.03 g, was then added carefully to the 2-{[2-(2-dimethylamino ethoxy)ethyl]methylamino}ethanol solution with stirring. The mixture was stirred at a constant rate for two minutes before 7.10 g of acrylamide was added. After the addition of acrylamide, the reaction mixture was stirred at 55° C. for 6 hours. The mixture was cooled to ambient temperature and neutralized with 0.80 g of concentrated sulfuric acid. The resulting mixture was filtered through a Celite layer. The filtrate was collected for foam application without further purification. Quantitative 1H NMR showed that the product was 94% pure.
