The process is used to prepare an N - [(aliphatic or aromatic) carbonyl)] - 2-aminoacetamide of formula wherein Ra has the formula wherein Raa is hydrogen, a optionally substituted aliphatic or substituted aromatic radical; Rb is hydrogen, an optionally substituted aliphatic or substituted aromatic radical; Rca and Rcb independently of one another are hydrogen, an optionally substituted aliphatic or substituted aromatic radical; Rd has the formula wherein Rda is an optionally substituted aliphatic or substituted aromatic radical; or Raa is substituted with a primary or secondary protected amine which, after deprotection, can be reacted with an ab or a db carbon atom, or with at least one of Rb, Rca or Rcb, each of which is substituted with at least activated carbonic acid, to form a 5-7 membered ring or Rb is substituted with a primary or secondary protected amine which after deprotection can be reacted with an ab or a db carbon atom, or with at least one of Rb, Rca or Rcd each of which is substituted with at least an activated carboxylic acid to form a 5-7 membered ring; or Rc and Rcd are independently substituted with a primary or secondary protected amine which upon deprotection can be reacted with a? ab or * db carbon atom or with at least one of Raa, Rb, Rca, Rcd and Rda, each of which is substituted with at least an activated carbamoyl acid to form a 5-7 membered ring; or Rda is substituted with a primary or secondary protected amine which upon deprotection can be reacted with at least one of Rca or |
