Description

  

  Verfahren zur Darstellung einer     N-substituierten    Verbindung der     Pyridonreihe.       Es wurde gefunden, dass man zu einer       N-substituierten    Verbindung der     Pyridonreihe     gelangen kann, wenn man     2-Dimethylamino-          äthoxypyridin-3-carbonsäureanilid    durch Er  wärmen umlagert.  



  Das entstandene     N-Dimethylaminoäthyl-          2-pyridon-3-carborisäureanilid    schmilzt bei 88 .  Es ist in organischen Lösungsmitteln, sowie  in Säuren löslich. Das farblose Monochlor  hydrat schmilzt bei<B>2180.</B>  



  Die neue Base soll     für    therapeutische  Zwecke Verwendung finden.  



  <I>Beispiel:</I>       2-Dimethylaminoäthoxypyridin    - 3 -     carbon-          säureanilid    wird durch Erhitzen auf etwa  220<B>0</B> bis 270   umgelagert.



  Process for the preparation of an N-substituted compound of the pyridone series. It has been found that an N-substituted compound of the pyridone series can be obtained if 2-dimethylamino ethoxypyridine-3-carboxylic acid anilide is rearranged by warming it.



  The resulting N-dimethylaminoethyl-2-pyridone-3-carboric anilide melts at 88. It is soluble in organic solvents as well as acids. The colorless monochlorohydrate melts at <B> 2180. </B>



  The new base will be used for therapeutic purposes.



  <I> Example: </I> 2-Dimethylaminoethoxypyridine - 3 - carboxylic acid anilide is rearranged by heating to around 220 <B> 0 </B> to 270.

PATENTANSPRUCH: Verfahren zur Darstellung einer N-sub- stituierten Verbindung der Pyridonreihe, da durch gekennzeichnet, dass man 2-Dimethyl- aminoäthoxypyridin-3-carbonsäureanilid durch Erwärmen umlagert. Das entstandene N-DimethylamiDoäthyl- 2-pyridon-3-carbonsäureariiiid schmilzt bei 88 . Es ist in organischen Lösungsmitteln, sowie in Säuren löslich. Das farblose Mono chlorhydrat schmilzt bei 218 . Die neue Base soll für therapeutische Zwecke Verwendung finden. PATENT CLAIM: Process for the preparation of an N-substituted compound of the pyridone series, characterized in that 2-dimethylaminoethoxypyridine-3-carboxylic acid anilide is rearranged by heating. The resulting N-dimethylamidoethyl-2-pyridone-3-carboxylic acid amide melts at 88. It is soluble in organic solvents as well as acids. The colorless monochlorohydrate melts at 218. The new base will be used for therapeutic purposes.
