摘要: The reaction of 2-aminothiobenzamide with either 2-iminocoumarin-3-carbonitrile or 2-iminocoumarin-3-thiocarboxamides has been studied. It established that in both cases, 2-(2-iminocoumarin-3-yl)quinazoline-4(3H)-thiones are formed as the result a two-step procedure. reactions arylamines and alkylating agents have
