title: Reactions of chloride salts of 7-amino-9-ethylguanine and 1-amino-3-methylbenzimidazoles with lead(IV) acetate: formation of 8-aza-9-ethylguanine and 1-methyl-1H-benzotriazoles.
abstract: Reaction of 7-amino-9-ethylguaninium chloride with lead(IV) acetate (LTA) in MeOH yielded 8-aza-9-ethylguanine. Similarly, the reaction of 1-amino-3-methylbenzimidazolium chloride or its substituted derivatives (6-methyl, 5,6-dimethyl and 5-nitro) with LTA gave the corresponding 1-methyl-1H-benzotriazole (or 1-methyl-2-azabenzimidazole) derivatives along with N-methylformananilide derivatives.
