Abstract
AbstractThe synthesis of 1,4,7,9‐tetraazabenzo[b]phenothiazine ring system from 4‐aminopyrimidine is reported. This new heterocyclic ring was obtained by converting a 4‐aminopyrimidine to the corresponding 5‐thiocyanato derivative followed by hydrolysis and subsequent treatment with 2,3‐dichloroquinoxaline. Several derivatives were obtained by using suitable substituted starting materials. Nitration with mixed nitric and sulfuric acids gave the corresponding 13‐nitro derivatives. Spectral analyses are in agreement with the assigned structures.
