  Die Kupplung wird beim vorliegenden  Verfahren mit Vorteil in alkalischem Medium.  durchgeführt. Hierbei kann man z. B. so  vorgehen, dass man das     1-(2'-Chlor-5'-sulf-          ainido)-plienyl-3-methyl-5-pyrazolon    mit der  erforderlichen     Men;e        Alkalihy        dro--#,y    d löst.  und den für die     Kupplung    benötigten     Alkali-          übersehuss    in Form eines     Alkaliearbonates          hinzufügt.        CTegebenenfalls    kann die Kupplung  auch unter Zusatz neutraler oder     basiseher     Lösungsmittel, wie z.

  Process for the preparation of a monoazo dye. It has been found that a valuable monoazo dye is obtained when inan dianotated 2-aniinobenzene-5-sulfonsätirc- atiilid-7 @ -earboxylic acid with 1- (2'-chloro-5'-sulfanii (lo) -l) lienyl-3-nietliyl-5-pyrazolone combined.



  When dry, the new dye is an orange-yellow substance that dissolves in hot water and hot sodium carbonate solution with a -clear color and dyes wool in yellow tones in an acid bath, which turns brownish and very good -ash-, when chromium-plating. walk- and borrowed earth. The dye is suitable.

   also look excellent for dyeing after the single bath or roinier method. The in the present process as starting material from 2-aminobenzene-5-sulfonic säureaniii <1-1-carboxylic acid can be prepared according to conventional, known methods who the, z. B. by converting \) - chlorobenzene-5-sulfonic acid eliloride-l-carbonate e finite aniline and the chlorine atom in the 2-chlorobenzene-5-sulphonsanreanilide-l-cai-bonsäiire.

         dtircli replaces the -NIIz group.



  The dianotation of the 2-ainobenzene-5-sulf'onic acid anilide-1-carbonsätire can also be carried out by methods known per se, advantageously by the so-called indirect method, that is, a solution containing an alkali salt of the diazotization component as well as the required amount of nitrite, finely combined with a dilute hydrochloric acid solution containing an excess of the theoretically required amount of acid.



  In the present process, the coupling is advantageously carried out in an alkaline medium. carried out. Here you can z. B. proceed in such a way that the 1- (2'-chloro-5'-sulf-ainido) -plienyl-3-methyl-5-pyrazolone is dissolved with the required amount of alkali metal hydro- #, y d. and add the excess alkali required for the coupling in the form of an alkali carbonate. If necessary, the coupling can also be carried out with the addition of neutral or basic solvents, such as.

   B. alcohol, pyridine, '@thanolamine, etc .. take place.



       Example: 29.2 parts of 2-Aininobenzol.-5-sulfonic acid anilide-1.-carbonsäui@e are dissolved in 300 parts of water with the addition of 8 parts of anhydrous sodium carbonate. After adding 7 parts of sodium nitrite, this solution is allowed to add to one of 40 parts 30; Add organic hydrochloric acid and so much Fis to the mixture that the reaction temperature is about 10 to 1.51 during the dianotation, and stir until the dianotation is complete.



  The suspension of the diazo compound is treated with a solution of 28.75 parts of 1- (2'-chloro-5'-sulfamido) -phenyl-3-methyl-5-pyrazolone in 200 parts of water, 6 parts of sodium hydroxide and 25 parts of anhydrous sodium carbonate 5 to <B> 100 </B> combined. The mixture is stirred until the coupling has ended and the dye is filtered off. It can be stirred again in water for further cleaning and filtered off like that.
