  Verfahren zur Herstellung des 1,     1'-Methylen-di=(2-ogy-3-naphthoesäure-          2'-methoayanilids).       Es wurde .gefunden,     da.B    man das 1,1-Me       thylen-di-(2-oxy-3-naphthoesäure-2'-methoxy-          anilid)    erhält, wenn man     1,1'-Methylen-di-          (2-oxy-3-naphthoesäure)    mit     o-Anisidin    in       Gegenwart    von     Kondensationsmitteln,    wie       Phosphortriehlorid    oder     Phosphoroxychlorid,

            behandelt.        Das        1,1'-Methylen-di-(2-oxy-3-          naphthoesä.ure-2'-methoxyanilid)        aus    Chlor  benzol umgelöst,     bildet    nahezu     weisse    Kri  stalle vom     S.    P.     '241-243'.    Das 1,1'-Me       thylen-di-(2-oxy-3-naphthoesäure-2'-methoxy-          anilid)    wird zur     Herstellung    von     Farbstoffen     verwendet.  



  <I>Beispiel:</I>       3,8,8    Teile     1,1'-Methylen-,di-(2-oxy-3-naph-          thoesäure)    werden in 400 Teilen     o-Anisidin          bei    100-110   gerührt.

   Bei dieser Tempera  tur     läBt    man innert :etwa einer Stunde  16 Teile     Phosphortriehlorid        zutropfen    und       rührt    5     Stunden    bei 1120-125'     weiter.    Hier-    auf wird     die        Reaktionsmasse    in     verdünnte     Salzsäure gegossen und :

  das .abgeschiedene  1,1'-     blethylen    -     di-(2    -     oxy-3-naphthoesäure-    2'  methoxyanilid) durch     Umlösen    in verdünn  ten     Ätzalkalien    und Fällen der von schlam  migen     Verunreinigungen    filtrierten     Lösung     mit Säure     gereinigt.  



  Process for the preparation of the 1,1'-methylene-di = (2-ogy-3-naphthoic acid-2'-methoayanilids). It has been found that 1,1-methylene-di- (2-oxy-3-naphthoic acid-2'-methoxy-anilide) is obtained when 1,1'-methylene-di- (2 -oxy-3-naphthoic acid) with o-anisidine in the presence of condensing agents, such as phosphorus trium chloride or phosphorus oxychloride,

            treated. The 1,1'-methylene-di- (2-oxy-3-naphthoic acid-2'-methoxyanilide) dissolved from chlorobenzene forms almost white crystals from S.P. '241-243'. The 1,1'-Me thylen-di- (2-oxy-3-naphthoic acid-2'-methoxy anilide) is used for the production of dyes.



  <I> Example: </I> 3.8.8 parts of 1,1'-methylene, di- (2-oxy-3-naphthoic acid) are stirred in 400 parts of o-anisidine at 100-110.

   At this temperature, 16 parts of phosphorus trichloride are added dropwise within about an hour, and stirring is continued for 5 hours at 1120-125 '. The reaction mass is then poured into dilute hydrochloric acid and:

  the .abgeschiedene 1,1'-blethylene - di- (2 - oxy-3-naphthoic acid- 2 'methoxyanilide) cleaned by dissolving in dilute caustic alkalis and precipitating the filtered solution with acid.
