  Verfahren zur Darstellung optisch aktiver o-Dioxyphenylalkamine. 



   Es wurde gefunden. dass die synthetischen, optisch inaktiven, razemischen o-Dioxyphenylalliamine durch ihrer   d-oder -weinsauren   Salze in die optisch aktiven Komponenten gespalten werden Rönnen, und dass man so z.   H.   zu dem l-o-Dioxyphenyläthanolmethylamin gelangen kann, welches identisch ist mit der für therapeutische Zwecke wichtigen Neben- 
 EMI1.1 
 halten. Es schmilzt dann bei   1490 C. Es   ist identisch mit dem d-weinsauren Salz der Neben-   nierenbase. Die   aus demselben durch Alkalilange abgeschiedene Base zeigt deren Schmelz- 
 EMI1.2 
 wird die   d-hase   in Form des schwer löslichen l-Tartrats abgetrennt. 



   In gleicher Weiso kann die Spaltung anderer razemischen o-Dioxyphenylalkamine mit Hilfe von d-Weinsüure ausgeführt werden.

  Process for the preparation of optically active o-dioxyphenylalkamines.



   It was found. that the synthetic, optically inactive, racemic o-dioxyphenylalliamines can be split into the optically active components by their d- or -tartaric acid salts, and that, for example, H. to the l-o-Dioxyphenyläthanolmethylamin, which is identical to the important for therapeutic purposes secondary
 EMI1.1
 hold. It then melts at 1490 C. It is identical to the d-tartaric acid salt of the adrenal base. The base separated from it by alkali length shows its melting point
 EMI1.2
 the d-hare is separated in the form of the poorly soluble l-tartrate.



   In the same way, the cleavage of other racemic o-dioxyphenylalkamines can be carried out with the aid of d-tartaric acid.
