Description
<B>Verfahren</B> zur <B>Herstellung eines</B> Hydrazons <B>eines</B> heterocyclischen <B>Aldehyds</B> Gegenstand des vorliegenden Patentes ist. ein Verfahren zur Herstellung eines neuen Hydrazons eines heterocyclischen Aldehyds, das dadurch gekennzeichnet ist, dass man Piperonal mit Isonikotinsäurehydrazid um setzt. Das so erhaltene Piperonal-isonikotin- säurehydrazon schmilzt bei 236 C. Es soll als Arzneimittel Verwendung finden.
<I>Beispiel</I> 69 Gewichtsteile Isonikotinsäurehydrazid werden in 1000 Volumteilen siedenden Alko hols gelöst und mit einer Lösung von 75 Ge wichtsteilen Piperonal in 1000 Volumteilen Alkohol versetzt. Nach kurzem Erwärmen kri- stallisiert das Piperonal-isonikotinsäurehydra- zon, das nach dem Abkühlen abgesaugt wird. Ausbeute 120 Gewichtsteile. Nach Umlösen aus Methanol zeigt es den F. 236 C.
<B> Process </B> for <B> producing </B> a </B> hydrazone <B> a </B> heterocyclic <B> aldehyde </B> is the subject of the present patent. a process for the preparation of a new hydrazone of a heterocyclic aldehyde, which is characterized in that piperonal is reacted with isonicotinic acid hydrazide. The piperonal-isonicotinic acid hydrazone thus obtained melts at 236 ° C. It is said to be used as a pharmaceutical.
<I> Example </I> 69 parts by weight of isonicotinic acid hydrazide are dissolved in 1000 parts by volume of boiling alcohol and a solution of 75 parts by weight of piperonal in 1000 parts by volume of alcohol is added. After a short period of warming, the piperonal-isonicotinic acid hydrazone crystallizes and is filtered off with suction after cooling. Yield 120 parts by weight. After dissolving from methanol it shows the F. 236 C.
