The first unambiguous synthesis of δ-carboline has been achieved starting with 3-amino-2-phenylpyridine. This was converted to the azide which was thermally cyclized to δ-carboline. The carboline gave a py-N-methiodide which was converted to the anhydronium base. The pKa of the anhydronium base was determined and its significance is discussed. The anhydronium base formed a methiodide which, on dry distillation, gave ind-N-methyl-δ-carboline. The spectral properties of the various derivatives of δ-carboline were examined and the bond structures of the anhydronium base and the methiodides are discussed.
