The 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
据报道由4-氨基嘧啶合成1,4,7,9-四氮杂苯并[ b ]吩噻嗪环系统。通过将4-氨基嘧啶转化为相应的5-硫氰酸根衍生物,然后水解并随后用2,3-二氯喹喔啉处理,获得了该新的杂环。通过使用合适的取代起始原料获得了几种衍生物。用硝酸和硫酸混合硝化得到相应的13-硝基衍生物。光谱分析与分配的结构一致。
