Versuchsvorschrift

Then 25.1 g of 2-(o-methoxyphenoxy) ethyl chloride, 33.40 g of potassium methacrylate, 11.17 g of potassium iodide, 50 ml of N,N-dimethylformamide, and a small amount of hydroquinone were placed in a 200 ml-flask equipped with a stirring device and a cooling pipe. The mixture was heated at 100° C. and stirred. The reacted mixture was refined by column chromatography using silica gel, and 24.8 g of 2-(o-methoxyphenoxy)ethyl methacrylate was produced.
