Die Ausgangsverbindungen der allgemeinen Formel II lassen sich in an sich bekannter Weise herstellen (siehe oben). The starting compounds of the general formula II can be prepared in a manner known per se (see above).
Die Alkylierung der Verbindungen der allgemeinen Formel II führt man gemäss der Erfindung durch Einwirkung von 1 bis 5 Moläquivalenten des Alkylierungsmittels der allgemeinen Formel III auf die Lösung der Verbindung der allgemeinen Formel II in einem inerten Lösungsmittel, in Gegenwart einer Base zur Bindung der in Freiheit gesetzten Säure, in einem Temperaturbereich von —40 bis +50 °C, durch. The alkylation of the compounds of the general formula II is carried out according to the invention by the action of 1 to 5 molar equivalents of the alkylating agent of the general formula III on the solution of the compound of the general formula II in an inert solvent, in the presence of a base to bind those released Acid, in a temperature range of -40 to +50 ° C.
Als Alkylierungsmittel der allgemeinen Formel III lassen sich Alkylhalogenide, vorzugsweise Alkyljodide oder Al-kylbromide, Allylbromid, Benzylbromid oder ©-Bromalkan-säuren und deren Ester, oder Schwefelsäurealkylester, wie Dimethylsulfat oder Diäthylsulfat, oder aliphatische oder aromatische Sulfonsäureester, beispielsweise Alkylmethan-sulfonate oder Alkyl-p-toluolsulfonate, verwenden. Suitable alkylating agents of the general formula III are alkyl halides, preferably alkyl iodides or alkyl bromides, allyl bromide, benzyl bromide or © bromoalkanoic acids and their esters, or alkyl sulfuric acid, such as dimethyl sulfate or diethyl sulfate, or aliphatic or aromatic sulfonic acid esters, for example alkyl methane sulfonates -p-toluenesulfonate.
Als inerte Lösungsmittel kann man polare aprotische Lösungsmittel, wie Dimethylformamid, Dimethylsulfoxid, Phosphorsäurehexamethyltriamid, Aceton oder flüssiges Ammoniak, verwenden. Polar aprotic solvents such as dimethylformamide, dimethyl sulfoxide, phosphoric acid hexamethyltriamide, acetone or liquid ammonia can be used as the inert solvent.
Als eine Base zur Bindung der freigesetzten Säure lässt sich eine starke Base, beispielsweise Natrium- oder Kalium-amid, Lithiumdiisopropylamid, Natriummethylat oder Na-trium- oder Kaliumhydroxid verwenden. Ein besonders vorteilhaftes Verfahren zur Herstellung der Verbindungen der allgemeinen Formel I liegt in der Alkylierung der Verbindungen der allgemeinen Formel II mit Alkylhalogeniden in flüssigem Ammoniak in Gegenwart von Natrium- oder Ka-liumamid, das in genanntem Medium (in situ) hergestellt wird. Die entstandenen Verbindungen der allgemeinen Formel I lassen sich aus dem Reaktionsgemisch mit gewöhnlichen Separations- und Isolierungsmethoden isolieren, beispielsweise durch Abdampfen des Lösungsmittels und Chromatographie und/oder durch Kristallisation der erhaltenen Rohprodukte. A strong base, for example sodium or potassium amide, lithium diisopropylamide, sodium methylate or sodium or potassium hydroxide, can be used as a base for binding the released acid. A particularly advantageous process for the preparation of the compounds of the general formula I is the alkylation of the compounds of the general formula II with alkyl halides in liquid ammonia in the presence of sodium or potassium amide, which is prepared in the medium mentioned (in situ). The resulting compounds of general formula I can be isolated from the reaction mixture using conventional separation and isolation methods, for example by evaporating off the solvent and chromatography and / or by crystallizing the crude products obtained.
1 -substituierte N-[8a-Ergolinyl]-N',N'-diäthylharnstoffe der allgemeinen Formel I stellen farblose kristalline Substanzen vom basischen Charakter dar, welche mit starken anorganischen oder organischen Säuren Additionssalze bilden. Zu therapeutischen Zwecken eignen sich wasserlösliche Salze mit pharmazeutisch unbedenklichen, nicht toxischen Säuren, wie beispielsweise Chlorwasserstoff-, Schwefel-, Methansul-fon-, Äthansulfon-, Malein-, Äpfel-, Wein, Zitronensäure u.ähnl. Die genannten Salze erhält man durch Einwirkung von mindestens 1 Moläquivalenten der Säure auf 1 Moläquivalent der Verbindung der allgemeinen Formel I in einem geeigneten inerten Lösungsmittel, vorzugsweise in Methanol, Äthanol, Aceton, Wasser oder in deren Gemischen. 1-Substituted N- [8a-ergolinyl] -N ', N'-diethylureas of the general formula I are colorless crystalline substances of basic character, which form addition salts with strong inorganic or organic acids. For therapeutic purposes, water-soluble salts with pharmaceutically acceptable, non-toxic acids, such as, for example, hydrochloric acid, sulfuric acid, methane sulfonic acid, ethane sulfonic acid, maleic acid, apple acid, wine, citric acid and the like are suitable. The salts mentioned are obtained by the action of at least 1 molar equivalent of the acid per 1 molar equivalent of the compound of the general formula I in a suitable inert solvent, preferably in methanol, ethanol, acetone, water or in mixtures thereof.
Die Verbindungen der allgemeinen Formel I sind bedeutsame Inhibitoren der Sekretion des Prolaktins und des Wachstumshormons bei Lebewesen. Sie können deshalb in der Human- und Veterinärtherapie zur Senkung des Prolaktins- und Wachstumshormonspiegels eingesetzt werden, beispielsweise bei der Behandlung der Hyperprolaktinämie, Akromegalie und des Parkinsonismus, oder zur Erhöhung des Spiegels der Gonadotropine, beispielsweise zum Hervorrufen der Brunst bei Säugetieren und zum Hervorrufen des Eierlegens bei Vögeln. The compounds of general formula I are important inhibitors of the secretion of prolactin and growth hormone in living beings. They can therefore be used in human and veterinary therapy to lower the level of prolactin and growth hormone, for example in the treatment of hyperprolactinemia, acromegaly and Parkinsonism, or to increase the level of gonadotropins, for example to induce the heat in mammals and to cause the Eggs laying in birds.
Das Verfahren zur Herstellung von 1-substituierten 8a-Ergolinylharnstoffen der allgemeinen Formel I ist in den nachfolgenden Beispielen näher erläutert, welche allerdings den Umfang der Erfindung keineswegs begrenzen. Die Schmelztemperaturen der Verbindungen wurden am Kofler-Block bestimmt und sind, wie auch die übrigen Temperaturangaben, in 'C angeführt. Die Werte der spezifischen Drehungsvermögen beziehen sich auf kristallösungsmittelfreie Substanzen. The process for the preparation of 1-substituted 8a-ergolinylureas of the general formula I is explained in more detail in the following examples, which, however, in no way limit the scope of the invention. The melting temperatures of the compounds were determined on the Kofler block and, like the other temperature data, are given in ° C. The values of the specific rotatory power refer to substances free of crystal solvents.

Man rührt das Reaktionsgemisch 2 Stunden bei Zimmertemperatur, dann gibt man weitere 0,284 g (2 mMol) Methyljodid zu und rührt das Gemisch noch 3 Stunden. Den anorganischen Anteil filtriert man ab, aus dem Filtrat destilliert man das Lösungsmittel unter vermindertem Druck ab, nimmt den Rückstand in ein Chloroform-Wasser-Gemisch auf, trocknet den organischen Anteil mit wasserfreiem Natriumsulfat und destilliert das Lösungsmittel unter vermindertem Druck ab. Das Rohprodukt (0,4 g) reinigt man durch Kieselgel-Säulenchromatographie, unter Verwendung eines Chloroform-Äthanol-Gemisches (95 : 5) zur Eluierung der Stoffe, und die vereinigten einheitlichen Fraktionen kristallisiert man nach Abdampfen der Lösungsmittel aus Aceton um. Man erhält die Titelverbindung (Formel I, R1 = R2 = Methyl) in Form von farblosen Kristallen mit Fp. 136 bis 138 °C; spezifisches Drehvermögen [a]D20 = +26,3° (c = 0,2, Pyridin).

The reaction mixture is stirred for 2 hours at room temperature, then a further 0.284 g (2 mmol) of methyl iodide are added and the mixture is stirred for a further 3 hours. The inorganic portion is filtered off, the solvent is distilled off from the filtrate under reduced pressure, the residue is taken up in a chloroform-water mixture, the organic portion is dried with anhydrous sodium sulfate and the solvent is distilled off under reduced pressure. The crude product (0.4 g) is purified by silica gel column chromatography, using a chloroform / ethanol mixture (95: 5) to elute the substances, and the combined uniform fractions are recrystallized from acetone after evaporation of the solvents. The title compound (formula I, R1 = R2 = methyl) is obtained in the form of colorless crystals with mp. 136 to 138 ° C; specific turning capacity [a] D20 = + 26.3 ° (c = 0.2, pyridine).

Nach Auflösen dieser Verbindung (etwa nach 30 Minuten) tropft man 385 mg (2,715 mMol) Methyljodid zu und rührt das Reaktionsgemisch 1 Stunde bei Siedetemperatur des Ammoniaks. Danach dampft man Ammoniak ab, nimmt den Rückstand in ein Chloroform-Wasser-Gemisch auf, wäscht den Chloroformanteil mit Wasser, trocknet ihn mit wasserfreiem Natriumsulfat und destilliert das Lösungsmittel unter vermindertem Druck ab. Das Rohprodukt liefert nach Umkristallisieren aus Aceton die Titelverbindung (Formel I, R2 = Methyl, R1 = Propyl) in Form von farblosen Kristallen mit Fp. 117 bis 119 °c; [a]D20 = +26,3° (c = 0,2, Pyridin). N- [D-1-Methyl-6-n-propyl-8a-ergolinyl] -N ', N'-diethylurea. To a solution of 62.4 mg (2.715 mmol) of sodium in about 100 ml of liquid ammonia is added with stirring 10 mg of iron / III / nitrate and after decolorization of the solution, 500 mg (1.357 mmol) of N- [D-6-propyl-8a-ergolinyl] -N ', N'-diethyl urea are added to the resulting sodium amide suspension . After this compound has been dissolved (approximately after 30 minutes), 385 mg (2.715 mmol) of methyl iodide are added dropwise and the reaction mixture is stirred for 1 hour at the boiling point of the ammonia. Then ammonia is evaporated off, the residue is taken up in a chloroform-water mixture, the chloroform portion is washed with water, dried with anhydrous sodium sulfate and the solvent is distilled off under reduced pressure.
