1.Amide has a charge on the nitrogen, the amine does not.
2.The commonplace name for a tryptamine precursor is indol-3-ylglyoxalylamide.which my be imperfect IUPAC but there you go. The structure this name produces is not the one typically desired. Adding a proper locant gives the correct structure.
