Verl'aliren zur Darstellung von Ergot.imiusalieylit. Gegenstand der vorliegenden Erfindung i=.t ein Verfahren zur Darstellung des bisher noch unbekannten Ergotaminsalizylates. A15 .@.usgangsxnaterial kann man sowohl die reine %)ase, z. 13.
ihre Kristallisation, aus wasser- lu ltigem Aceton, wie sie in Patent 1Tr. 80321 erwähnt ist, oder ein ergotaminreiches Al- lraloidrolilurodulzt verwenden und in leuterein Fall die Salzbildung zur Abtrennung des Ergotainins von Begleitstoffen verwenden.
Das Verfahren zur Darstellung, von Er- gotaminsalizylat beruht darauf, dass man auF Ergotamin eine ausreichende Menge von Sali- zylsäure nach Art der Salzbildung einwirken hisst.
Zur Darstellung von Ergotaminsalizylat in fester kristallisierter Form löst man die freie Base zweckmässig in mit Wasser misch baren, indifferenten, organischen Lösungs mitteln, wie .Alkohol oder Holzgeist, auf iind fügt die SalizyIsäure zil, worauf die kristal- linische Ausscheidung von Ergotaminsali- zylat einsetzt,
oder man fallt das Salz aus einer Lösung des Ergotamins in mit Wasser nicht mischbaren organischen Lö sungsmit- teln, wie Äther oder Benzol, indem man vor- richtig verdünnte & tlizylsii.iire so lailge zu setzt, als eine Fällung entsteht. Man kristal lisiert darauf die abfiltrierte amorphe Fäl lung aus einem geeigneten Lösungsmittel, z. B. Holzgeist.
Ergotaminsalizylat bildet schöne I%ristallisationsverbindungen mit or- ganischen Lösungsmitteln, \wie zum Beispiel l1@Tethyl- und Äthylalkohol.
Zur Darstellung von Ergotaminsalizylat in wässerigen Lösungen, sowohl reinen, als auch solchen, denen Iionservierungsinittel, wie Alkohol und Glyzerin, zugesetzt sind, fügt man dem Lösungsmittel die ausreichende Menge Saliz3-ls < iure zu und versetzt die so verdünnte Säure mit einer konzentrierten Lö sung der Ergotaminbase in einem organischen Lösungsmittel, z. B. Alkohol.
Wie die freie Base, so erleiden auch Ergotaminsalizylat und seine Lösungen na- inentlicli am Licht durch Luftsauerstoff oxy- clative Veränderungen unter Gelb- und Braun- Arbung. Man vermeidet dieselben, indem man bei der Herstellung und bei der Aufbewah rung von Ergotaminsalizylat und seiner L ö- sungen,
insbesondere beim Bereiten und Ab füllen von Injektionslösungen, unter Ver-

Verl'aliren for the representation of Ergot.imiusalieylit. The subject of the present invention is a method for the preparation of the previously unknown ergotamine salicylate. A15. @. Starting material one can use both the pure%) ase, e.g. 13.
their crystallization, from aqueous acetone, as described in patent 1Tr. 80321 is mentioned, or use an ergotamine-rich Al- lraloidrolilurodulzt and in some case use the salt formation to separate the ergotainine from accompanying substances.
The process for the preparation of ergotamine salicylate is based on the fact that a sufficient amount of salicylic acid is added to ergotamine in the manner of salt formation.
To prepare ergotamine salicylate in solid crystallized form, the free base is expediently dissolved in water-miscible, indifferent organic solvents, such as alcohol or wood spirit, and the salicylic acid is added, whereupon the crystalline precipitation of ergotamine salicylate begins ,
or the salt is precipitated from a solution of ergotamine in organic solvents which are immiscible with water, such as ether or benzene, by adding properly diluted glycylic acid so that a precipitate is formed. One then crystallizes the filtered amorphous precipitate from a suitable solvent, e.g. B. Wood Spirit.
Ergotamine salicylate forms beautiful crystallization compounds with organic solvents, such as, for example, methyl and ethyl alcohol.
For the preparation of ergotamine salicylate in aqueous solutions, both pure and those to which ion preservatives such as alcohol and glycerine have been added, a sufficient amount of salicylic acid is added to the solvent and a concentrated solution is added to the diluted acid the ergotamine base in an organic solvent, e.g. B. Alcohol.
Like the free base, ergotamine salicylate and its solutions naturally undergo oxidative changes with yellow and brown discoloration in the light of atmospheric oxygen. The same can be avoided by taking care of the manufacture and storage of ergotamine salicylate and its solutions,
especially when preparing and filling injection solutions, with
