Description
- a) Fraktionierte Kristallisation, bei der die unterschiedlichen Kristallisierbarkeiten oder Löslichkeiten der Isomeren der Verbindung (VIII) als solche, eines Salzes der Verbindung (VIII) mit Halogenwasserstoff (HBr- oder HCl-Salz) oder eines Derivates der Verbindung (VIII) mit einer in an sich bekannter Weise eingeführten Schutzgruppe (z. B. Monochloracetyl oder Dichloracetyl) an ihrer 2-Aminogruppe.
- b) Isolierung durch Chromatographie und
- c) ein Verfahren, bei dem die Verbindung (VIII) oder die eine Schutzgruppe an ihrer 2-Aminogruppe enthaltende Verbindung (VIII) an ihrer Ester-Stellung in an sich bekannter Weise zu einem Carbonsäurederivat der Formel (III) hydrolysiert und das syn-Isomere allein durch Ausnutzung des Unterschiedes in der Hydrolysengeschwindigkeit zwischen den syn- und anti-Isomeren selektiv isoliert wird.
