Das Verfahren wird vorteilhafterweise ausgeführt, indem 20 man die Reduktion mittels eines komplexen Hydrides, wie beispielsweise Natriumborhydrid, in Gegenwart von Trifluor-essigsäure, durchgeführt. The process is advantageously carried out by carrying out the reduction using a complex hydride, such as sodium borohydride, in the presence of trifluoroacetic acid.

Die Reduktion kann beispielsweise bei Temperaturen von —10° bis +40°C erfolgen. Als Lösungsmittel verwendet man 25 Trifluoressigsäure, Äther, Tetrahydrofuran, Dioxan oder deren Gemische. Vorzugsweise setzt man einen 1,5 bis 10 molaren Überschuss an Natriumborhydrid ein. Zu Verbindungen der Formel I gelangt man aber auch durch Umsetzen von Verbindungen der Formel II mit überschüssigem Zink-30 staub in konzentrierter Salzsäure. The reduction can take place, for example, at temperatures from -10 ° to + 40 ° C. 25 trifluoroacetic acid, ether, tetrahydrofuran, dioxane or mixtures thereof are used as solvents. A 1.5 to 10 molar excess of sodium borohydride is preferably used. However, compounds of the formula I can also be obtained by reacting compounds of the formula II with excess zinc 30 dust in concentrated hydrochloric acid.

Die erfindungsgemäss hergestellten Verbindungen der Formel I sind bei Raumtemperatur kristalline Verbindungen, die mit anorganischen oder organischen Säuren beständige, bei Raumtemperatur kristallisierte Salze bilden. The compounds of the formula I prepared according to the invention are compounds which are crystalline at room temperature and which form stable salts which crystallize at room temperature with inorganic or organic acids.

3s Die neuen Verbindungen der Formel I, insbesondere 1,1 -Dimethyl-3-[6-methyl-2,3ß-dihydro-9-ergolen-8ß-ylmethyl]harnstoff, zeigen interessante pharmakologische Eigenschaften und können deshalb als Heilmittel Verwendung finden. 3s The new compounds of formula I, in particular 1,1 -dimethyl-3- [6-methyl-2,3ß-dihydro-9-ergolen-8ß-ylmethyl] urea, show interesting pharmacological properties and can therefore be used as medicines.

40 Sie zeichnen sich in der pharmakologischen Prüfung durch ausgeprägte antihypertensive Wirkung aus, wie an der wachen hypertonen Grollmannratte sowie am wachen hyper-tonen Goldblatthund mit Dosen von 0,05 bis 0,5 mg pro kg Körpergewicht des Testtieres festgestellt wurde. Ihre Anwen-45 dung bei Hypertonien jeglicher Genese ist dadurch angezeigt. 40 They are characterized in the pharmacological test by their pronounced antihypertensive effect, as was found in the awake hypertonic Grollmann rat and the awake hyper-toned gold leaf dog with doses of 0.05 to 0.5 mg per kg body weight of the test animal. Their use in hypertension of any origin is indicated.

Die zu verwendenden Dosen variieren naturgemäss je nach Art der Applikation und des zu behandelnden Zustandes. Im allgemeinen werden befriedigende Resultate erreicht mit einer täglichen Dosis von 0,01 bis 2,5 mg pro kg Körperge-50 wicht des Testtieres; diese Dosis kann nötigenfalls in 2 bis 3 Anteilen oder auch als Retardform verabreicht werden. Für grössere Säugetiere liegt die Tagesdosis bei etwa I bis 200 mg. Für orale Applikationen enthalten die Teildosen etwa 0,5 bis 100 mg der Verbindung neben festen oder flüssigen Träger-55 substanzen oder Verdünnungsmitteln. The doses to be used naturally vary depending on the type of application and the condition to be treated. In general, satisfactory results are achieved with a daily dose of 0.01 to 2.5 mg per kg of body weight of the test animal; if necessary, this dose can be administered in 2 to 3 portions or as a slow-release form. For larger mammals, the daily dose is around I to 200 mg. For oral applications, the partial doses contain about 0.5 to 100 mg of the compound in addition to solid or liquid carrier substances or diluents.

Die neuen Verbindungen der Formel I können als Arzneimittel allein oder in entsprechenden Arzneiformen für orale, enterale oder parenterale Verabreichung verwendet werden. The new compounds of the formula I can be used as pharmaceuticals alone or in appropriate pharmaceutical forms for oral, enteral or parenteral administration.

In dem nachfolgenden Beispiel, welches die Erfindung so näher erläutert, ihren Umfang aber in keiner Weise einschränken soll, erfolgen alle Temperaturangaben in Celsiusgraden. In the following example, which explains the invention in greater detail but is not intended to restrict its scope in any way, all the temperatures are given in degrees Celsius.

Nach beendeter Natriumborhydrid-Zugabe wird 20 Minuten bei Zimmertemperatur gerührt und anschliessend auf Eis/Wasser gegossen. Unter starkem Rühren gibt man festes Kaliumcarbonat zu, bis die Suspension pH 8 erreicht und schüttelt dreimal mit Methylenchlorid aus. Die vereinigten, organischen Phasen werden mit Natriumsulfat getrocknet, filtriert und eingedampft.

After the sodium borohydride addition has ended, the mixture is stirred at room temperature for 20 minutes and then poured onto ice / water. Solid potassium carbonate is added with vigorous stirring until the suspension reaches pH 8 and shaken out three times with methylene chloride. The combined organic phases are dried with sodium sulfate, filtered and evaporated. The result is 4.5 g of beige foam, which on 120 g of silica gel H (type 60) with methylene chloride / methanol (9: 1) + 0.3% NH? (conc.) chro-
