Abstract
A method was worked out for the preparation of isatin α-semicarbazone, the starting material for the synthesis of 3-hydroxy-l,2,4-triazacarbazoles, and the structure of the latter was refined. Nucleophilic exchange of 3-chloro-l,2,4-triazacarbazole (which was obtained for the first time) with amines, hydrazines, and arylhydrazines was studied.
