unknown 1-(alkylamino)benzimidazoline-2-thiones. These compounds can be more conveniently obtained on a preparative scale by thiolation of 1-alkylacetamidobenzimidazoles with subsequent hydrolytic elimination of the acetyl group. When 1-(dialkylamino)benzimidazoles are fused with sulfur, they are converted into 1-(dialkylamino)benzimidazoline-2-thiones. By alkylation of 1-(methylamino)- and 1-(dieth
与 1-氨基苯并咪唑不同,1-烷基氨基苯并咪唑在与硫融合时被硫醇化而不消除 N-氨基,产生以前未知的 1-(烷基氨基)苯并咪唑啉-2-硫酮。这些化合物可以通过 1-烷基乙酰氨基苯并咪唑的硫醇化作用,随后水解消除乙酰基,以制备规模更方便地获得。当 1-(二烷基氨基)苯并咪唑与硫稠合时,它们会转化为 1-(二烷基氨基)苯并咪唑啉-2-硫酮。通过在碱性介质中用碘甲烷对 1-(甲氨基)-和 1-(二乙氨基)苯并咪唑啉-2-硫酮进行烷基化,制备相应的 2-(甲硫基)苯并咪唑。
