The action of carbon disulfide on diethyl mesoxalate o-aminophenylhydrazone in pyridine gives 1-amino-2-mercaptobenzimidazole.Alkylation of the latter with alkyl halides in an alcohol solution of alkali leads to the formation of the previuosly unknown 1-amino-2-alkylbenzimidazoles, while the action of phenacyl bromides leads to 3-aryl-2H-1,3,4-thiadiazinobenzimidazoles.
