Description
Verfahren zur Herstellung eines basischen Esters. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines basischen 1:aters. Das Verfahren ist dadurch gekenn zeichnet, class man einen reaktionsfähigen Ester von Methyl-di-isobutyl-essigsäure-(- oxy-propyl)-ester, wie z. B. einen Halogen wasserstoff- oder Arylsulfonsäureester, mit Dinietliylaniin umsetzt.
Die erhaltene neue Verbindung-, der Dimethylaminopi-opylester der Metliyl-di-isobuty1-essigsäure, ist eine Base vom Siedepunkt. 1.17 bis 1.190 unter 13 min Druck. Sie lässt sich mit. anorganischen oder organischen Säuren in Salze überführen. Sie soll therapeutische Verwendung finden.
<I>Beispiel:</I> '?6,3 Teile des aus Methyl-di-isobut.y l-essig- säureefilorid und Pi-opy l.enchlorhy drin erhal tenen Met.liyl-cli-isobittyl-(;,-ehlor-propyl)- esters werden in der Wärme mit 9 Teilen Di- methylamin umgesetzt. Das Gemisch wird in verdünnter Salzsäure gelöst und durch Aus- schütteln mit Äther von geringen Mengen von Neutralteilen befreit..
Aus der sauren, wässri- geii Lösung wird hierauf durch Zusatz von konzentriertem Ammoniak der Basisehe Ester abgeschieden. Er wird in Ätlier aufgenommen, die ätherische Lösung mit Wasser gewaschen und getrocknet.
Der nach dein Abdestillieren des Äthen als Rückstand erhaltene Dinietlivl- aminopropylester der 1Iethyl-di-isobutyl-essig- säure siedet bei 147 bis 1490 -unter 13 inm Druck.
Process for the preparation of a basic ester. The present patent is a process for the production of a basic 1: ether. The method is characterized in that one class is a reactive ester of methyl-di-isobutyl-acetic acid - (- oxy-propyl) ester, such as. B. a halogen hydrogen or Arylsulfonsäureester, reacts with Dinietliylaniin.
The new compound obtained, the dimethylaminopi-opyl ester of methyl-di-isobutyl-acetic acid, is a base with a boiling point. 1.17 to 1.190 under 13 min pressure. She lets herself with. convert inorganic or organic acids into salts. It should find therapeutic use.
<I> Example: </I> '? 6.3 parts of the met.liyl-cli-isobittyl- (;, obtained from methyl-di-isobut.y l-acetic acid fluoride and pi-opy l.enchlorhy) -ehlor-propyl) esters are reacted with 9 parts of dimethylamine in the heat. The mixture is dissolved in dilute hydrochloric acid and small amounts of neutral parts are removed by shaking with ether.
The base ester is then deposited from the acidic, aqueous solution by adding concentrated ammonia. It is taken up in Ätlier, the ethereal solution washed with water and dried.
The dinietlivl-aminopropyl ester of ethyl-di-isobutyl-acetic acid, obtained as residue after distilling off the ether, boils at 147 to 1490 -under 13 m pressure.
