Procedimiento

Phenoxycarbonylpropyleneurea 8.2 g (37.3 mmol) and hydroxyethylstyrene 5 g (37.3 mmol) were dissolved into dioxane 90 ml by heating. Into the solution obtained was added dibutyltin dilaurate 0.5 g, and the mixture was heated for 6 hours with stirring. After the reaction the solution was concentrated to give a solid mass, which was then purified by column chromatography. The title compound 3.9 g (yield: 40%) was obtained, which was analyzed to:
