| titleOfInvention | The production method of S-2-aminobutanamide |
| abstract | The invention discloses a production method of S-2-aminobutyramide, which belongs to the technical field of chemical synthesis. The invention uses L-(+)-methionine as a raw material, and in the presence of alcohol or ether solvents, through chlorine-containing organic Carboxylate effect, demethylation thiohydroxylation and formation of S-2-amino-4-hydroxybutyric acid hydrochloride, followed by hydroxyl bromination to give S-2-amino-4-bromobutyric acid hydrobromide, S-2-amino-4-bromobutyric acid methyl ester hydrochloride is obtained by carboxymethyl esterification, nickel-catalyzed hydrogenation dehalogenation is converted into S-2-aminobutyric acid methyl ester, and finally aminolysis generates S-2-amino Butanamide. The invention has the advantages of high yield and good safety. |
