Article abstract of DOI:10.1515/HC.2002.8.4.329

A new five-component condensation of isothiocyanates, sulfur, 2-cyanomethylbenzimidazole, triethylamine and carbon disulfide furnishes triethylammonium 3-aryl-[1,3]thiazolo[4′,5′:4,5]pyrimido[1,6-a]benzimidazole- 2(3H)-thioxo-5-thiolates, the alkylation of which gives 3-aryl-5-R-thio-[1,3]thiazolo[4′,5′:4,5]pyrimido[1,6- a]benzimidazole-2(3H)-thiones.
