| titleOfInvention | Method for producing high-purity N-protecting group-S-phenylcysteine |
| abstract | (57) [Summary] [PROBLEMS] To provide a method for efficiently removing contaminating impurities. SOLUTION: An organic solvent selected from aromatic hydrocarbons, organic acid esters, and halogenated hydrocarbons is added to an alkaline reaction solution in which a protective group is introduced into an amino group of S-phenylcysteine in an aqueous medium in an aqueous medium. After extracting the solubles, the aqueous solution layer was separated, the pH of the aqueous solution was adjusted to acidic, and the acidic aqueous solution was converted to aromatic hydrocarbons, organic acid esters, And a method for producing an N-protecting group-S-phenylcysteine, which comprises adding an organic solvent selected from the group consisting of a halogen-based hydrocarbon and an organic solvent and extracting the organic solvent from the solvent. |
