Reaktionsschritte

20 g (0.106 mol) of benzalhydantoin, 14.9 g (0.117 mol) of isobutyl acrylate and 1.2 g (0.02 mol) of potassium hydroxide were added to 150 ml of DMF, and the mixture was stirred at 110° C. for 2 hours. After cooling, the reaction solution was added with 300 ml of toluene and crystallized. The crystals were filtered out and dried to obtain 27.2 g of isobutyl 4-benzylidene-2,5-dioxo-1-imidazolidinepropionate (yield: 81%).
