quinoxaline hydrazone, diketonesAbstract
In order to create medicinal preparations of some pharmacological action we deemed topical to develop an convenient preparative method for the synthesis of new isomeric qunoxalines. By condensation of 4-chlorophenylenediamine (1) with diphenylethanedione, 6-chloro-2,3-diphenylquinoxaline (2) was synthesized. Quinolinhydrazine (3) was obtained by interaction of the mentioned chlorine products with hydrazine hydrate, and the corresponding 2,3-diphenyl-6-quinoxalinehydrazone was obtained by the action of ethylester of pyruvic acid on the latter. Composition and structure of synthesized compounds is determined by element analysis and physical methods of investigation.
