Description

  

  Verfahren zur Darstellung eines     Ogykarbazolkarbonsäurearylamids.       Es wurde gefunden, dass man ein als  wertvolles Zwischenprodukt für die Herstellung  von     Farbstoffen    verwendbares     Oxykarbazol-          karbonsäurearylamid    erhält, wenn man eine  Verbindung der Formel  
EMI0001.0005     
    in der X einen bei der Reaktion sich abspal  tenden     Substituenten,    zum Beispiel -OH oder  Halogen, bedeutet, mit     p-Methoxy-o-methyl-          anilin    umsetzt.  



  <I>Beispiel:</I>  24,1     gr        9-Methyl-2-oxyliarbazol-3-karbon-          säure    und 15,6     gr        1-Amino-2-methyl-4-          methoxybenzol    werden in 500 cm'     Toluol    ge  löst. Bei     60-6511    lässt man unter Rühren  innerhalb     '/z    Stunde 7     gr        Phosphortrichlorid          zutropfen,    erwärmt dann langsam zum Sie  den und hält das Reaktionsprodukt 8 Stun  den bei dieser Temperatur.

   Dann macht man  mit     Sodalösung    alkalisch, bläst mit Wasser-    dampf alles Flüchtige ab, saugt von dem  ausgeschiedenen     Arylid    ab und wäscht mit  Wasser aus.     Klan    erhält das     9-Methyl-2-oxy-          karbazol    - 3 -     kar        boylam        ino    - 2' -     methyl-    4'-     me-          thoxybenzol    vom F. P. 183  . Es stellt ein       gelbstichig    weisses Pulver dar.



  Process for the preparation of an ogykarbazole carboxylic acid aryl amide. It has been found that an oxycarbazole carboxylic acid arylamide which can be used as a valuable intermediate for the preparation of dyes is obtained if a compound of the formula
EMI0001.0005
    in which X is a substituent which splits off during the reaction, for example —OH or halogen, is reacted with p-methoxy-o-methyl aniline.



  <I> Example: </I> 24.1 g of 9-methyl-2-oxyliarbazole-3-carbonic acid and 15.6 g of 1-amino-2-methyl-4-methoxybenzene are dissolved in 500 cm of toluene . At 60-6511, 7 grams of phosphorus trichloride are added dropwise with stirring within 1/2 hour, then slowly warmed to the and the reaction product is kept at this temperature for 8 hours.

   Then you make alkaline with soda solution, blow off everything volatile with steam, suck off the precipitated arylide and wash out with water. Klan receives 9-methyl-2-oxy-carbazole-3-carboylamino-2 '-methyl-4'-methoxybenzene from F. P. 183. It is a yellowish white powder.
