New substituted 3-amino-5,7,8-trihalo-6-hydroxycinnoline-4-carbonitriles 7 and 8 and the 3-amino-5-chloro-6-hydroxy-benzo[h]cinnoline-4-carbonitrile 9 were synthesized in two-steps starting from tetrahalo-1,4-benzoquinones or dichloro-1,4-naphthoquinones, malononitrile and hydrazine.
新的取代的3-氨基5,7,8-三卤代-6- hydroxycinnoline -4-腈7和8和3-氨基-5-氯-6-羟基-苯并[ ħ〕噌啉-4-腈9合成从四卤代1,4-苯醌或二氯-1,4-萘醌,丙二腈和肼开始,分两步进行。
