      Tei.-fahren        zür    Darstellung eines     Oxyearboiisäurearylide".       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung eines     Oxyphenyl-          arylaminearboi)säui#earylides,    dadurch gekenn  zeichnet,

       dass    man die durch     Kohlensäure-          druckschmelze    der     Alkalisalze    von     3-Oxy-4'-          chlordiphenylamin    darstellbare     S-Oxy-4'-chlor-          diphenylaminearbonsätire    mit     6-Ainino-l-me*-          thyl-3-oxybenzol    in     Stispensions-    oder Lö  sungsmitteln in Gegenwart eines Kondensa  tionsmittels erwärmt.  



  Das erhaltene     3-Oxy-4'-chlordiphe.nylamin-          earbonsäure-p-oxy-o-inethylanilid    bildet ein  hellbraunes Pulver ohne bestimmten Schmelz  punkt, das in Natronlauge leicht, in den  meisten organischen Lösungsmitteln auch in  der Wärme sehr schwer löslich ist.

      Partial for the preparation of an Oxyearboiisäurearylide ". The present patent relates to a method for the preparation of an Oxyphenyl-arylaminearboi) säui # earylides, characterized by

       that the S-oxy-4'-chlorodiphenylamine carbonates, which can be prepared by carbonic acid pressure melt of the alkali salts of 3-oxy-4'-chlorodiphenylamine, are mixed with 6-amino-1-methyl-3-oxybenzene in dissolving agents heated in the presence of a condensation agent.



  The resulting 3-oxy-4'-chlordiphe.nylamin- carboxylic acid-p-oxy-o-ynethylanilide forms a light brown powder with no specific melting point, which is easily soluble in sodium hydroxide solution, and very poorly soluble in most organic solvents even when heated.



  It is intended to be used as an intermediate in the manufacture of dyes. <I> Example: </I> Züi <B> 132 </B> parts of 3-oxy-4'-chlorodiphenylamino-carboxylic acid and <B> 61.5 </B> parts of 6-amino-1-methyl -8-oxybenzene in <B> 1000 </B> parts of toluene are allowed to slowly flow in the <B> 30 </B> parts of phosphorus drive boride at 60-7011.

   The reaction mass is then heated to <B> 1100 </B> for about 8 hours and then, after making it alkaline with soda solution, toluene is removed by steam distillation. The remaining 3-oxy-4- i chlordiphenylaminearl) oi-acid-p-oxy-o-methylanilide is dissolved in caustic soda for the purpose of cleaning, filtered and precipitated with carbonic acid.

PATENTANSPRUCH: Verfahren zur Darstellung eines Oxycar- bonsäurearylides, dadurch gekennzeichnet, dass man die durch KohlensäuredruckschmeIze der Alkalisalze von 3-Oxy-4'-chlordiphenyl- amin darstellbare 3-Oxy-4'-ch[ordiphenylamiti- carbonsäure mit 6-Affiino-l-methyl-3-oxybeii- zol in Suspensions- oder Lösungsmitteln in Gegenwart eines Kondensationsmittels er wärmt. PATENT CLAIM: Process for the preparation of an oxycarboxylic acid arylide, characterized in that the 3-oxy-4'-ch [ordiphenylamitic acid, which can be prepared by carbonic acid pressure melt of the alkali metal salts of 3-oxy-4'-chlorodiphenylamine, is mixed with 6-affiino-1 -methyl-3-oxybeiizole in suspending or solvents in the presence of a condensing agent it warms. Das erhaltene 3-Oxy-4'-chlol-dipheiiylawiii- earbon#s,äui-e-p-oxy-o-inethylanilid bildet ein hellbraunes Pulver ohne bestimmten Schmelz punkt, das in Natronlauge leicht, in den meisten organischen Lösungsmitteln auch in der Wärme sehr schwer löslich ist. Es soll als Zwischenprodukt zur Ilerstellung von Farbstoffen verwendet werden. The resulting 3-oxy-4'-chlol-dipheiiylawiii- earbon # s, äui-ep-oxy-o-ynethylanilid forms a light brown powder without a certain melting point, which is easy in sodium hydroxide solution, in most organic solvents also very much in the heat is sparingly soluble. It is intended to be used as an intermediate for the production of dyes.
