The action of acid on 6‐( p ‐tolylhydrazino)‐2‐thiouracil gives appreciable amounts of the stable Fischer intermediate, 5‐(2 ‐amino‐5 ‐tolyl)‐6‐amino‐2‐thiouracil. This compound undergoes intramolecular cyclization at high temperatures, and represents the first reported isolation of a diamine intermediate derived from a Fischer‐type indolization reaction.
