It has recently been shown that, under the conditions of acid catalysis, the antibioticfervenulin (la) adds indole at the angular C-4a atom. At the same time, it is reported that the 3-substituted derivatives of the antibiotic (la) are transformed into the xanthine derivatives as the result of the nucleophilic attack by formamide on the C-8a atom in the pyrimidotriazine nucleus [2]. The transformation
