Description

  

      Ziisatzpateiit    zum Hauptpatent Nr. 92088.    Verfahren zur Herstellung einer     heteroeyclischen        Verbindung    der     Naphtalinreihe.       Es wurde gefunden, dass man zu einer  technisch wertvollen     lieteroct=clisclien    Ver  bindung der     Naphtalinreihe    gelangen kann.  wenn man auf     Benzyl-ss-naplityliiuiin,    gege  benenfalls in Gegenwart von     Verdünnungs-          und        Iiondensationsinitteln.        Oialylchlorid    ein  wirken lässt.

   Die so erhaltene neue Verbin  dung, das     ss-Benz-%-lnaphtindol-1:        2-dion,    - bil  det ein rotes     kristallinisches    Pulver und  schmilzt bei 185  .  



       Beispiele:     1. 233 Teile     Benzj-I-ss-naplitylamiii    werden  in 635 Teile     OxalvIcblorid        eingetracen.    Die       Mischung        wird        eini--e    Zeit bei     gewöhnlicher     Temperatur     durcligerübrt.    hierauf langsam  bis zum     Siedepunkt    des     O-xal@-Iclilori < ls    er  wärmt und dieses     abdestilliert.    Das so     erhal.          tene    rohe     ss-Beiizvlnaplit-iiidol-1:2-dion    wird  aus Benzol umgelöst.

      2. 233 Teile     Benzyl-ss-naphtylamin    werden  in eine Lösung, bestehend aus 190,5 Teilen       Oxalylelilorid    und 570 Teilen Benzol, einge  tragen und das Ganze einige Stunden am       Riiel{flusshiililer    gekocht.     Hierauf    werden das  Benzol und das     überschüssige        Oxalylchlorid          abdestilliert.    Das so erhaltene     ss-Benzylnapht-          indol-7:2-dioii    wird aus Benzol     umgelöst.  



      Additional file for main patent no. 92088. Process for the production of a heteroyclic compound of the naphthalene series. It has been found that a technically valuable lieteroct = clisclien connection of the naphthalene series can be achieved. if you use benzyl-ss-naplityliiuiin, if necessary in the presence of diluents and ion densifiers. Oialyl chloride can act.

   The new compound obtained in this way, the ss-benz -% - inaphthindole-1: 2-dione, - forms a red crystalline powder and melts at 185.



       Examples: 1. 233 parts of Benzj-I-ss-naplitylamiii are ingested in 635 parts of oxalvic chloride. The mixture is stirred for a time at ordinary temperature. then slowly to the boiling point of the Oxal @ -Iclilori <oil he warms and this distilled off. So get it. tene crude ss-beiizvlnaplit-iiidol-1: 2-dione is redissolved from benzene.

      2. 233 parts of benzyl-ss-naphthylamine are introduced into a solution consisting of 190.5 parts of oxalyleliloride and 570 parts of benzene and the whole thing is boiled for a few hours on a flow heater. The benzene and the excess oxalyl chloride are then distilled off. The ss-benzylnaphth-indole-7: 2-diol thus obtained is redissolved from benzene.
