The reaction of 2-aminobenzimidazole 1 with benzonitrile in the presence of anhydrous stannic chloride gives N-(benzimidazol-2-yl)arylamidines 2 in 65-82% yield. Cyclocondensation of 2 with triethyl orthoesters affords 2-aryl-4-alkyl-1,3,5-triazino[1,2-a]

2-Aminobenzimidazoles (1) react with benzonitriles in the presence of anhydrous stannic chloride to give N-(benzimidazol-2-yl)arylamidines (2).Oxidative cyclisation of 2 with lead tetraacetate in dry benzene leads to 2-aryltriazolobenzimidaz
