We have developed a novel amidinesynthesis that allows the preparation of heterocyclic amidines that were previously unknown and difficult to prepare by published methods. The route involves the lithiation of heterocycles by the action of n-BuLi followed by reaction with carbon disulfide and trapping with methyl iodide, yielding a dithioate ester. The latter, when heated in 20% methanolic ammonia
