Abstract
Reaction of 1-[(methylthlo)thiocarbonylmethyl]pyridinium iodide with substituted o-phenylenediamines gave 1-[(2’-benzimidazolyl)methyl]pyridinium salts which were acylated and mono- and dialkylated by standard procedures. In addition. 2-(1’-piperidinylmethyl)benzimidazole derivatives were prepared by reduction of pyridinium moiety with sodium dithionite.
