  Verfahren zur Herstellung eines neuen basisch substituierten   Fettsäure-       (2-halogen-6-methyl-anilids).   



   Gegenstand des vorliegenden Patentes bildet ein Verfahren zur Herstellung eines neuen basisch substituierten Fettsäure-(2-halogen-6  methyl-anilids),    welches dadurch   gekennzeich-    net ist, dass man eine Verbindung der Formel
EMI1.1     
 in welcher   X    einen reaktionsfähigen, während der Reaktion sich abspaltenden Rest bedeutet, mit   N-Methyl N-cyelohexyl-amin umsetzt.   



   Der Rest X kann in einem Halogenatom oder einem sonstigen für den Austausch gegen den basischen Rest geeigneten reaktionsfähigen Substituenten, wie z. B. einer   Alkylsul-    fonyloxy-oder   Arylsulfonyloxygruppe,    bestehen. Der Austausch der Gruppe X gegen den Methyl-eyelohexyl-aminrest erfolgt z. B. durch einfaches Erwärmen mit Methyl-cyclohexylamin gegebenenfalls in Gegenwart eines basisch   reagierenden Ysationsmittels    oder von Methyl-cyclohexyl-amin im Überschuss. Das N-Methyl-N-cyclohexyl-amino-acet  (2-chlor-6-methyl-anilid)    ist ein farbloses   01.   



  Das   Hydroehlorid    der Base schmilzt bei 164 bis   166".   



   Das neue Anilid soll als   Lokalanästhetikum    und als Zwischenprodukt zur Herstellung weiterer Derivate Verwendung finden.



   Beispiel:
36 Gewiehtsteile   Chloracet- (2-chlor-6-me-    thyl-anilid) (gewonnen durch Umsetzen von 2  Chlor-6-methyl-anilin    mit Chloracetylehlorid in Gegenwart von Natriumacetat,   Schmp.    140 bis   141 )    werden in 80 Gewichtsteilen Äthanol suspendiert und mit 57 Gewichtsteilen N-Me  thyl-N-eyelohexyl-amin versetzt.

  Process for the production of a new basic substituted fatty acid (2-halogen-6-methyl-anilide).



   The subject matter of the present patent is a process for the preparation of a new basic substituted fatty acid (2-halogen-6-methyl-anilide), which is characterized in that a compound of the formula
EMI1.1
 in which X denotes a reactive radical which is split off during the reaction, reacts with N-methyl N-cyelohexyl-amine.



   The radical X can be in a halogen atom or any other reactive substituent suitable for replacement with the basic radical, such as. B. an alkylsulfonyloxy or arylsulfonyloxy group exist. The exchange of group X against the methyl-eyelohexyl-aminerest takes place z. B. by simply heating with methyl-cyclohexylamine, optionally in the presence of a basic Ysationsmittel or methyl-cyclohexyl-amine in excess. The N-methyl-N-cyclohexyl-amino-acet (2-chloro-6-methyl-anilide) is a colorless 01.



  The hydrochloride of the base melts at 164 to 166 ".



   The new anilide is to be used as a local anesthetic and as an intermediate product for the production of further derivatives.



   Example:
36 parts by weight of chloroacet- (2-chloro-6-methyl-anilide) (obtained by reacting 2-chloro-6-methyl-aniline with chloroacetyl chloride in the presence of sodium acetate, melting point 140 to 141) are suspended in 80 parts by weight of ethanol and with 57 parts by weight of N-methyl-N-eyelohexyl-amine. The temperature rises slightly and a large part of the reaction mixture goes into solution. The mixture is then stirred for 4 hours at room temperature and then for a few hours at 65 to 75 hours. A sample with water and then mixed with dilute hydrochloric acid,

   again results in a solution of the precipitate. The alcohol and the excess N-methyl-N-cyclohexyl-amine are then blown off with steam and, after cooling, the remaining 61 is taken up in ether becomes. 42 parts by weight of pure N-methyl-N-eyelohexyl-amino-acet- (2-chloro-6-methyl-anilide) are obtained. The reaction with cyclohexylamine can also take place in benzene.
