Description

  

  Verfahren zur Herstellung von     Diphenyl-morpholinoäthyl-essigsäureäthylester.            Gegenstand    des vorliegenden Zusatzpatentes  ist ein Verfahren zur Herstellung von     Diphe-          nylmorpholinoäthyl-essigsäureäthylester,    wel  ches dadurch gekennzeichnet ist, dass man       N-Morpholino-äthylhalogenid    auf     Diphenyl-          acetonitril    in Gegenwart eines Halogenwas  serstoff abspaltenden Mittels einwirken lässt  und das so erhaltene basische     Nitril    in den  zugehörigen     Äthylester    überführt.

      <I>Beispiel:</I>    6 g     Natriumamid    in 100 cm' Benzol wer  den mit 27 g     Diphenylacetonitril    und dann  mit 22,5 g     N-Morpholino-äthylchlorid    umge  setzt, wobei die im Hauptpatent angegebenen  Bedingungen zugrunde gelegt werden. Nach  dem Aufarbeiten und     Umkristallisieren    aus       Hexahydrobenzol    erhält man 28g     Diphenyl-          morpholinoäthyl-acetonitril    als fast weisses  Pulver vom     Sinp.        82t .     



  <B>30</B> g     Diphenyl-morpholinoäthyl-aceto-          nitril    werden mit 120 g 70%iger Schwefel  säure unter den Bedingungen des Haupt  patentes zur Säure verseift und die erhaltene    Säure mit     Äthylalkohol    verestert. Nach der  Aufarbeitung erhält man 24 g     Diphenyl-          morpholinoäthyl-essigsäureäthylester    als     dik-          kes,    fast farbloses Öl, das unter 4 mm Druck  bei 218-222  siedet. Sein Chlorhydrat stellt  farblose Kristalle dar, die bei 166  schmelzen.



  Process for the preparation of diphenyl-morpholinoethyl-acetic acid ethyl ester. The subject of the present additional patent is a process for the preparation of Diphenylmorpholinoäthyl-acetic acid ethyl ester, wel Ches is characterized in that N-morpholino-ethyl halide is allowed to act on diphenyl acetonitrile in the presence of a hydrogen-releasing agent and the basic nitrile thus obtained in the associated ethyl ester transferred.

      <I> Example: </I> 6 g of sodium amide in 100 cm of benzene are reacted with 27 g of diphenylacetonitrile and then with 22.5 g of N-morpholino-ethyl chloride, based on the conditions specified in the main patent. After working up and recrystallization from hexahydrobenzene, 28 g of diphenylmorpholinoethyl-acetonitrile are obtained as an almost white powder from Sinp. 82t.



  <B> 30 </B> g of diphenylmorpholinoethyl acetonitrile are saponified with 120 g of 70% sulfuric acid under the conditions of the main patent and the acid obtained is esterified with ethyl alcohol. After working up, 24 g of diphenylmorpholinoethyl-acetic acid ethyl ester are obtained as a thick, almost colorless oil which boils at 218-222 under 4 mm pressure. Its chlorohydrate is colorless crystals that melt at 166.

PATENTANSPRUCH: Verfahren zur Herstellung von Diphenyl- morpholinoäthyl - essigsäureäthylester, da durch gekennzeichnet, dass man N-Morpho- lino-äthylhalogenid mit Diphenylacetonitril in Gegenwart eines Halogenwasserstoff ab spaltenden Mittels umsetzt und das so er haltene basische Nitril in den zugehörigen Äthylester überführt. Das erhaltene Produkt ist ein dickes, fast farbloses Öl, das unter 4 mm Druck bei 218 bis 222 siedet. Sein Chlorhydrat stellt farb lose Kristalle dar, die bei 166 schmelzen. PATENT CLAIM: Process for the production of diphenyl morpholinoethyl - ethyl acetate, characterized in that N-morpholino-ethyl halide is reacted with diphenylacetonitrile in the presence of an agent which splits off hydrogen halide and the basic nitrile thus obtained is converted into the associated ethyl ester. The product obtained is a thick, almost colorless oil that boils at 218-222 under 4 mm pressure. Its hydrochloride is colorless crystals that melt at 166. Die neue Verbindung ist ein hervorragendes Spas- molyticum und Analgeticum. The new compound is an excellent spasmolytic and analgesic.
