Procedure
Following the procedure of Example 1, α-cyano-β-ethoxy-N-ethoxycarbonylacrylamide is reacted with phenylhydrazine to give α-cyano-β-phenylhydrazino-N-ethoxycarbonylacrylamide, which in turn is cyclized by heating in tetralin, yielding 5-cyano-1-anilino-2,4-pyrimidinedione. The foregoing compound has been reported by G. Shaw, J. Chem. Soc., 1955, 1834-1840.
