Versuchsvorschrift

One hundred gram (450 mmol) of phenoxycarbonylpropyleneurea and 59 g (450 mmol) of hydroxyehtyl methacrylate were dissolved in 900 ml of dioxane at 85° to 90° C. Then, 400 mg of dibutyltin dilaurate was added thereto and allowed to mix for 13 hours with heat. After completion of the reaction, the mixture was concentrated and recrystalized with ether to obtain 90 g of 2-methacryloyloxyethyloxycarbonylpropyleneurea (77.5% yield).
