Procedure

2-(2-dimethylaminoethoxy)ethyl methacrylate (8 g) was dissolved in acetone (20 g) and small amounts of hydroquinone (approx. 0.1 g) was added followed by the addition of bromoethane (8 g). The mixture was stirred at room temperature for 24 hours and the solvent was removed under reduced pressure at 25° C. Product was obtained as an amorphous solid. Yield 12.2 g.
