   Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung neuer N-(3-Phenyl-2-propenyl)-naphthyl-methylamine der Formel I,
EMI1.3     
 worin
R, für Wasserstoff oder eine Alkylgruppe,

EMI1.4     
 worin R1, R2, R3, R4, R5, R6 und R, obige Bedeutung besitzen, hydriert und die erhaltenen Verbindungen der Formel I gegebenenfalls in ihre Säureadditionssalze überführt.



   Das erfindungsgemässe Verfahren kann beispielsweise ausgeführt werden, indem man eine Verbindung der Formel II in einem unter den Reaktionsbedingungen inerten Lösungsmittel, z. B. in einem niederen Alkohol, wie Methanol oder Äthanol, in einem chlorierten Kohlenwasserstoff, wie Methylenchlorid, in Pyridin oder in einem Ester, wie Essigsäureäthylester, löst und nach bekannten Methoden hydriert, z. B. unter Verwendung eines Katalysators wie Palladium oder Platin, das vor

Aus dem Reaktionsgemisch können die Endprodukte nach an sich bekannten Methoden isoliert und gegebenenfalls gereinigt werden.



   Die durch R1 und R2 symbolisierten Alkylgruppen besitzen vorzugsweise 1 bis 6, insbesondere 1 bis 4 Kohlenstoffatome und bedeuten beispielsweise die Methylgruppe.

   Die Verbindungen der Formel I besitzen chemotherapeutische Eigenschaften. Insbesondere besitzen die Verbindungen eine antimykotische Wirkung, wie sich durch Untersuchungen in vitro unter Verwendung von Myceten (z. B. von Trichophyton quinckeaneum) sowie in vivo am experimentellen Hautmykose-Modell am Meerschweinchen zeigen lässt. Bei diesem Modell wird die Substanz in Polyäthylenglykol aufgenommen und 7 Tage hindurch einmal täglich auf der infizierten Hautoberfläche verrieben. Die antimykotische Wirkung konnte ab einer Konzentration von 0,1-0,6% festgestellt werden. Die Verbindungen der Formel I können daher als Antimykotika verwendet werden.

  Die Verbindungen der Formel I können in
Form der freien Basen oder in Form pharmazeutisch unbe denklicher Säureadditionssalze verwendet werden, wobei die
Salze grössenordnungsmässig die gleiche Wirksamkeit besitzen wie die entsprechenden freien Basen. Geeignete Säureaddi tionssalze sind die Hydrochloride, Hydrogenfumarate und    Naphthalin- 1 ,5-di-sulfonate.   



   Die Verbindungen der Formel I können mit üblichen pharmazeutisch unbedenklichen Verdünnungs- oder Träger mitteln vermischt und in Form von Salben oder Tinkturen ver abreicht werden.
