Conclusions

  1. 1.

    A series of 1-alkyl(aryl)-2-methyl-3-carbethoxy-4,5-dioxo-7-dimethylaminoindoles was obtained by oxidative animation of 5-hydroxyindole derivatives.

  2. 2.

    Monoarylhydrazones of 1-alkyl (aryl)-2-methyl-3-carbethoxy-4,5,6,7-tetraoxoindoles were prepared by the reaction of dimethylaminoquinones of the indole acidic salts in aryldiazonium series with medium.

  3. 3.

    It was established that the reaction of 1,2-dimethyl-3-carbethoxy-4,5-dioxo-7-dimethylaminoindole with o-nitrophenyldiazonium sulfate at pH 7.0–8.0 leads to the aryldimethylaminoquinone.
