実験手順
A mixture of 8.8 g (0.03 mol) of α-cyano-β-(4-chloroanilino)-N-ethoxycarbonylacrylamide and 40 ml of ortho-dichlorobenzene is heated at reflux. After about 2 hours, crystals appear and the mixture is allowed to cool to room temperature. The mixture is filtered to yield 5-cyano-1-(4-chlorophenyl)uracil, m.p. 236°-239°.
