Procedure

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 7.3 g of 2-{[2-(dimethylamino) ethyl]methylamino}ethanol. Sodium hydride, 0.014 g, was then added carefully to the of 2-{[2-(dimethylamino) ethyl]methylamino}ethanol with stirring. The mixture was stirred at a constant rate for two minutes before 3.55 g of acrylamide was added. After the addition of acrylamide, the reaction mixture was stirred at 50° C. for 6 hours. The mixture was cooled to ambient temperature. Concentrated sulfuric acid, 0.034 g, then was added to neutralize the product mixture. The resulting mixture was filtered through a Celite layer. The filtrate was collected for foam application. Quantitative 1H NMR showed that the product was 94% pure.
