Description

Gegenstand der deutschen Auslegeschrift 1 122 514 ist ein Verfahren zur Herstellung von blutdrucksteigerndem 2-Äthyl-3,3-diphenyl-propen-(2)-yl-amin.The subject of German Auslegeschrift 1 122 514 is a process for the production of blood pressure-increasing 2-ethyl-3,3-diphenyl-propen- (2) -yl-amine.

Es hat sich nun gezeigt, daß man auf analogem Wege, nämlich durch Hydrierung von l-Propyl-2-hydroxy-2,2-diphenyl-propionitril und anschließende Abspaltung von Wasser aus dem entstandenen 2-Propyl-3,3-diphenyl-3-hydroxy-propyl-amin das 2-Propyl-3,3-diphenyl-propen-(2)-yl-amin erhält. Dieser Stoff besitzt die gleichen pharmakologischen Eigenschaften, insbesondere die anhaltende blutdrucksteigernde Wirkung, nur ist diese Wirkung sehr viel ausgeprägter. Diese langanhaltende blutdrucksteigernde Wirkung geht aus folgender Gegenüberstellung hervor:It has now been shown that an analogous route, namely by hydrogenation of 1-propyl-2-hydroxy-2,2-diphenyl-propionitrile and subsequent elimination of water from the 2-propyl-3,3-diphenyl-3-hydroxypropylamine formed the 2-propyl-3,3-diphenyl-propen- (2) -yl-amine is obtained. This substance has the same pharmacological properties especially the sustained antihypertensive effect, but this effect is much more pronounced. This long-lasting blood pressure-increasing effect can be seen from the following comparison:

Bei erniedrigtem Ausgangsblutdruck ist die blutdrucksteigernde Wirkung stärker und länger anhaltend als bei überhöhtem oder normalem Ausgangsblutdruck.If the initial blood pressure is reduced, the blood pressure-increasing effect is stronger and longer-lasting than with excessive or normal initial blood pressure.

Das ausgefällte 2-Propyl-3,3-diphenyl-3-hydroxy-propyl-amin wird abgesaugt. Schmp. 108 bis 1100C.13.1 g of l-PropyW-hydroxy ^^ - diphenyl-propionitrile are dissolved in 400 ml of glacial acetic acid, 200 mg of platinum contact are added, and then it is hydrogenated. After the uptake of hydrogen has ended, the contact is filtered off and the filtrate is evaporated to dryness in vacuo. The residue is dissolved in water, hydrochloric acid is added until the reaction is acidic, the undissolved material is filtered off and the filtrate is added dropwise to 20% sodium hydroxide solution. The precipitated 2-propyl-3,3-diphenyl-3-hydroxypropyl-amine is filtered off with suction. Mp. 108 to 110 0 C.
