Synthesis Of 8-[(2-Ethylimino-6-Substitutedamino)-1,3,5-Dithiazino- Imino]-1- Methyl-6-Phenyl-4h-[1,2,4]Azolo [4,3-A] [1,4] Benzodiazepines

Recently in this laboratory a novel series of 8-[(2-ethylimino-6-substitutedamino)-1,3,5- dithiazino]imino-1-methyl-6-phenyl-4H-[1,2,4]triazolo[4,3a][1,4]benzodiazepine was synthesized by the interactions of 8-(ethyl-2,4-dithibiureto)-1-methyl-6-phenyl-4H-[1,2,4] triazolo [4,3- a][1,4]benzodiazepine [VA(a)] with substituted isocyanodichlorides (VIIa-f) in 50% acetone[1]ethanol medium. The structure determination of synthesized compounds was done on the basis of elemental analysis, chemical characteristics and spectral studies.
