Description

  

  Verfahren zur     Darstellung    von     1-Dibenzylaminopropan-2-ol.       Gegenstand der vorliegenden Erfindung  ist ein Verfahren zur Darstellung von     1-Di-          benzylaminopropan-2-ol,    welches dadurch ge  kennzeichnet ist, dass man     1-Aminopropan-2-          ol    mit     Benzylehlorid,    am besten bei einer Tem  peratur zwischen     60-1100,    umsetzt.  



  Das zur Herstellung von neuen Heilmit  teln und Farbstoffen verwendbare neue Ver  fahrensprodukt ist ein unter 6 mm Druck  um 188   C, unter 3 mm Druck um 168   sie  dendes farbloses Öl.  



  <I>Beispiel:</I>  75 Teile 1-     Aminopropanol(2)    und     2"03     Teile     Benzylchlorid    werden in analoger Weise,  wie in Beispiel 1 des Hauptpatentes ange  geben ist, unter Eintragen von 140 Teilen       Kaliumcarbonat    zur Reaktion gebracht. Nach  analoger Aufarbeitung erhält man das     1-Di-          benzylaminopropanol(2)    als unter 6 mm Druck  um 188  , unter 3 mm um 168   übergehendes  farbloses<B>01.</B>



  Process for the preparation of 1-dibenzylaminopropan-2-ol. The present invention relates to a process for the preparation of 1-di-benzylaminopropan-2-ol, which is characterized in that 1-aminopropan-2-ol is reacted with benzyl chloride, preferably at a temperature between 60-1100 .



  The new process product that can be used for the manufacture of new medicinal products and dyes is a colorless oil under 6 mm pressure at 188 C, under 3 mm pressure at 168 degrees.



  <I> Example: </I> 75 parts of 1-aminopropanol (2) and 2 "03 parts of benzyl chloride are reacted in a manner analogous to that given in Example 1 of the main patent, adding 140 parts of potassium carbonate Working up, the 1-di-benzylaminopropanol (2) is obtained as a colorless 01 which fades by 188 under 6 mm pressure and by 168 under 3 mm
