| titleOfInvention | PROCESS FOR OBTAINING A DIPEPTIDE DERIVATIVE |
| abstract | The invention relates to a method for obtaining a dipeptide derivative. The aim of the invention is to provide a simple and industrially advantageous method for separating the addition compound. According to the invention, an organic solvent suitable for forming a binary phase system with water is mixed with an aqueous mixture containing as a solid component a dipeptide ester derivative of formula I wherein R deep 1 is a lower alkyl group, R deep 2 is a side chain group of an amino acid is n, n is 1 or 2, X is a benzyloxycarbonyl group which may have a nuclear substituent, and Y is a hydrogen ion. a. Thereafter, the resulting mixture is allowed to settle to form an organic solvent phase containing a substantial amount of the dipeptide derivative in the solid state and an aqueous phase. The organic solvent phase is separated from the aqueous phase and the dipeptide derivative is recovered from the organic solvent phase. |
