실험 절차

Following the method of Example 1, N-ethoxycarbonylcyanoacetamide is heated with triethyl orthoacetate and acetic anhydride to give α-cyano-β-ethoxy-β-methyl-N-ethoxycarbonylacrylamide, which in turn is reacted with 2,4,6-trichlorophenylhydrazine. The resulting compound α-cyano-β-methyl-β-(2,4,6-trichlorophenylhydrazino)-N-ethoxycarbonylacrylamide (m.p.=183°-184°) is cyclized, yielding 5-cyano-6-methyl-1-(2,4,6-trichloroanilino)-2,4-pyrimidinedione, m.p.=>305°.
