Description

  

  Verfahren zur Darstellung     Yon        3-Chlor-lL-N-(r-rnethoxy-ss-oxypropyl)-          n-butylaminobenzol.       Gemäss dem im Hauptpatent beschriebe  nen Verfahren erhält man     N-(r-Ä.thoxy-ss-          oxypi-opyl)-n-butylaminobenzol,    indem man       Epichlorhydrin    auf     n-Butylaminobenzol    bei  erhöhter Temperatur zur     Einwirkung    bringt  und das so erhaltene Produkt mit     äthyl-          alkoholischem    Alkali weiter umsetzt.  



  Wie nun weiter gefunden wurde, kann  man in ganz analoger Weise auch das     3-          Chlor-l-N-(r    -     inethoxy-/3-        o.xypropyl)-n-butyl-          aminobenzol    herstellen, wenn man     Epichlor-          hydrin    auf     3-Chloi--1-butylaminoberizol    bei  erhöhter Temperatur     einwirken    lässt und  das so erhaltene Produkt mit     methyl-          alkoholischein    Alkali umsetzt. Die neue Ver  bindung soll als Zwischenprodukt für die  Herstellung von     Farbstoffen    dienen.  



  <I>Beispiel:</I>  <B>367</B> Teile     3-Chlor-l-butylaminobenzol     werden mit 187 Teilen     Epichlorhydrin    wäh  rend 5 Stunden auf 130-140 erhitzt. Nach    dem Abkühlen setzt man eine Lösung von  90     gr        Ätznatron    in 1200 Teilen Methanol  hinzu und kocht dann die Lösung einige  Stunden am     R,ückflusskühler.    Die Aufarbei  tung geschieht wie in Beispiel 1 des Haupt  patentes. Es werden 310 Teile     3-Chlor-l-          N(r-methoxy-(3-oxypropyl)n-b        utylamin    ob     enzol     erhalten.     Kpi2=200-202 .  



  Method for the preparation of 3-chloro-IL-N- (r-methoxy-ss-oxypropyl) -n-butylaminobenzene. According to the process described in the main patent, N- (r-Ä.thoxy-ss- oxypi-opyl) -n-butylaminobenzene is obtained by exposing epichlorohydrin to n-butylaminobenzene at an elevated temperature and the product thus obtained with ethyl alcoholic alkali continues to react.



  As has now also been found, 3-chloro-IN- (r-inethoxy- / 3-o.xypropyl) -n-butyl-aminobenzene can also be prepared in a completely analogous manner if epichlorohydrin is converted to 3-chloro Lets -1-butylaminoberizole act at an elevated temperature and the product thus obtained is reacted with methyl alcoholic alkali. The new connection will serve as an intermediate for the manufacture of dyes.



  <I> Example: </I> <B> 367 </B> parts of 3-chloro-l-butylaminobenzene are heated to 130-140 for 5 hours with 187 parts of epichlorohydrin. After cooling, a solution of 90 grams of caustic soda in 1200 parts of methanol is added and the solution is then boiled for a few hours on a reflux condenser. The processing takes place as in Example 1 of the main patent. 310 parts of 3-chloro-1- N (r-methoxy- (3-oxypropyl) n-butylamine ob enzene) are obtained. Kpi2 = 200-202.
