3-substituted (chloro, bromo, fluoro or methyl) 7-(3,3-dimethyl-1-triazeno)-10-methylphenothiazines were synthesized as potential antitumor agents. Treatment of p-substituted anilines with ammonium thiocyanate in the presence of bromine gave 6-substituted 2-aminobenzthiazoles which, after methylation with methyl iodide were hydrolyzed in 50% potassium hydroxide to give 5-substituted 2-methylaminothiophenols
合成了一系列3-取代的(氯,溴,氟或甲基)7-(3,3-二甲基-1-三叠氮基)-10-甲基吩噻嗪作为潜在的抗肿瘤剂。p的治疗在溴存在下,用硫氰酸铵取代苯胺得到6-取代的2-氨基苯并噻唑,用碘代甲烷甲基化后,将其在50%氢氧化钾中水解,以中等收率得到5-取代的2-甲基氨基苯硫酚。甲基氨基硫酚与3,4-二氯硝基苯在乙醇中在氮原子下缩合,得到加合物,该加合物在铜和碘化亚铜的催化下在二甲基甲酰胺中环化,得到3-取代的7-硝基-10-甲基吩噻嗪。硝基被氯化亚锡还原为氨基官能团。胺重氮化,然后与二甲胺偶合,得到相应的三氮烯。
