When CO, H 2 and NH 3 are allowed to react at 200-700°C in the presence of nickel, alumina, or clay catalysts, amino acids are found among the products in yields of 0·-0·1 per cent. Purines, pyrimidines and hydrocarbons are also formed. Identifications were made by use of an amino acid analyzer. Although some contamination had occurred, the following amino acids appear to have been definitely synthesized: glycine, -alanine, -alanine, sarcosine, aspartic acid, glutamic acid, arginine, histidine, lysine and ornithine. Evidence is less conclusive for leucine, isoleucine, valine and proline.
