実験手順

Into a solution of 15.9 g of ethyl-β-amino-β-ethoxy acrylate in 30 ml of acetonitrile there was dropped 11.9 g of phenyl isocyanate while cooling, and the resulting mixture was allowed to stand at room temperature for 5 hours. The acetonitrile was then distilled away. To the residue was added 100 ml of ether, which was then dried over anhydrous sodium sulfate. The ether was distilled away and the residue obtained was distilled under reduced pressure. Thus, 12 g of ethyl-β-phenylureido-β-ethoxy acrylate of a boiling point of 83° to 84° C./0.5 mmHg was obtained.
