EMI0001.0001     
  
    Yerfaliren <SEP> zur <SEP> Darstellung <SEP> eines <SEP> Oxycarbonsäurcat-ylides.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung eines     Oxyphenyl-          arylamincarbonsäurearylides,    dadurch     ge-          kennzeichnet,

      dass     inan    die     durch        Kohlensäure-          druckschinelze    der     Alkalisalze    von     3-Oxy-4'-          methyldiphenylamin    darstellbare     3-Oxy-4'-          niethyldiplienylatiiincarbonsäure    mit     p-Nitro-          anilin    in     Suspensions-    oder     Lösungsmitteln     in Gegenwart eines Kondensationsmittels  erwärmt.  



  Das erhaltene     3-Oxy-4'-methyldiphenyl-          ainiucarbonsäure-p-nitroariilid    ist ein zitronen  gelbes Pulver, das nach dem     Umkristallisieren     aus Chlorbenzol den Schmelzpunkt 207   C  zeigt.  



  Es soll als Zwischenprodukt zur Herstel  lung von     Farbstoffen    verwendet werden.  <I>Beispiel:</I>  Zu 48,6 Teilen     3-Oxy-4'-methyldiphenyl-          aminearbonsäure    und 27,6 Teilen p-Nitroani-         lin    in 1000 Teilen     Toluol        werden    12 Teile       Phosphortriehlorid    bei 60-70   langsam zu  fliessen gelassen.

   Die Reaktionsmasse wird  hierauf noch etwa 8 Stunden auf<B>110"</B> er  wärmt und dann nach dem     Alkalischmachen     mit     Sodalösung        Toluol    durch     yVasserdanipf-          destillation    entfernt.     Das        zurückbleibende          3-Oxy-4'-niethyldiphenylamincarbonsäure-p-          nitroanilid@wird    zwecks Reinigung in Natron  lauge gelöst, filtriert und mit Kohlensäure  gefällt.



  
EMI0001.0001
  
    Yerfaliren <SEP> for the <SEP> representation <SEP> of a <SEP> oxycarboxylic acid catylide. The present patent relates to a process for the preparation of an oxyphenyl arylamine carboxylic acid arylide, characterized in that

      that inan the 3-oxy-4'-niethyldiplienylatiiincarbonsäure which can be prepared by carbonic acid pressure melt of the alkali salts of 3-oxy-4'-methyldiphenylamine is heated with p-nitroaniline in suspending or solvents in the presence of a condensing agent.



  The 3-oxy-4'-methyldiphenyl-ainiucarboxylic acid-p-nitroariilide obtained is a lemon-yellow powder which, after recrystallization from chlorobenzene, has a melting point of 207 ° C.



  It is intended to be used as an intermediate in the manufacture of dyes. <I> Example: </I> To 48.6 parts of 3-oxy-4'-methyldiphenylaminearboxylic acid and 27.6 parts of p-nitroaniline in 1000 parts of toluene, 12 parts of phosphorus trichloride are slowly allowed to flow at 60-70 .

   The reaction mass is then warmed to 110 "for about 8 hours and then, after making it alkaline with soda solution, toluene is removed by vasserdanip distillation. The remaining 3-oxy-4'-niethyldiphenylaminecarboxylic acid p-nitroanilide is for cleaning purposes dissolved in sodium hydroxide solution, filtered and precipitated with carbonic acid.
