Description

  

  Verfahren zur Herstellung eines     Aminoarylsulfons.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Aminaaryl-          sulfons,    dadurch gekennzeichnet, dass man       4-Chlorphenylmethylsulfon    mit     Methylamin     kondensiert.  



  Das so erhaltene, bisher unbekannte 4  Methylaminophenylmethylsulfon kristallisiert  aus Alkohol in farblosen     Nädelchen    vom  Schmelzpunkt<B>128-1290</B> C und soll als  Zwischenprodukt zur Herstellung von Farb  stoffen und Heilmitteln Verwendung finden.       Beispiel:     10 Teile     4-Chlorphenylmethylsulfon    wer  den mit 80 Teilen einer 25     o/oigen    wässerigen       Methylaminlösung    in einem Druckgefäss etwa  20 Stunden auf 195-200o C erhitzt. Nach  dem Erkalten filtriert man das gebildete    Umsetzungsprodukt ab, wäscht es mit Wasser  und trocknet es.



  Process for the preparation of an aminoarylsulfone. The present patent relates to a process for the preparation of an amine aryl sulfone, characterized in that 4-chlorophenylmethyl sulfone is condensed with methylamine.



  The previously unknown 4-methylaminophenylmethylsulfone obtained in this way crystallizes from alcohol in colorless needles with a melting point of <B> 128-1290 </B> C and is intended to be used as an intermediate for the production of dyes and medicinal products. Example: 10 parts of 4-chlorophenylmethylsulfone are heated with 80 parts of a 25% aqueous methylamine solution in a pressure vessel at 195-200 ° C. for about 20 hours. After cooling, the reaction product formed is filtered off, washed with water and dried.
