3-arylidineamino-5H-1,2,3-triazino[5,4-b]indol-4-ones 3 was obtained (80–86%). The reaction of 4-methoxybenzylidene derivative 3e with hydrazine hydrate, in ethanol, gave 3-amino-5H-1,2,3-triazino[5,4-b]indol-4-one 4 (64%). However, by treating 3e in boiling hydrate, 3-aminoindole-2-carbaldehyde azine 5 was obtained (44%). By boiling 1 in N,N-dimethylformamide, 3-amino-5H-pyrimido[5,4-b]indol-4-one, 6 was obtained (52%)
用3-氨基吲哚-2-碳酰肼开始1一系列亚芳基腙的2以良好的产率(79-85%)中的溶液获得。用亚硝酸处理2后,获得了一系列3-芳基氨基5 H -1,2,3-三嗪[5,4 - b ]吲哚-4-酮3(80-86%)。4-甲氧基亚苄基衍生物3e与水合肼在乙醇中的反应得到3-氨基-5 H -1,2,3-三嗪[5,4 - b ]吲哚-4-酮4(64%)。然而,通过在沸腾的水合物中处理3e,获得了3-氨基吲哚-2-甲醛甲醛5(44%)。煮沸1英寸得到N,N-二甲基甲酰胺,3-氨基-5 H-嘧啶基[5,4 - b ]吲哚-4-酮6,(52%)。
