Description
Verfahren zur Herstellung von N-Pyridyl-(2)-N-brombenzyl-N', N'-dialkyl-äthylendiaminen Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von N-Pyridyl-(2)-N-brombenzyl-N',N'-dialkyläthylendiaminen der allgemeinen Formel in der R, und R2 Alkylreste, von denen mindestens einer mehr als 1 Kohlenstoffatom enthält, vorzugsweise Äthylreste, bedeuten und das Bromatom in o-, m- oder p-Stellung gebunden ist.Process for the preparation of N-pyridyl- (2) -N-bromobenzyl-N ', N'-dialkyl-ethylenediamines The invention relates to a process for the preparation of N-pyridyl- (2) -N-bromobenzyl-N', N'-dialkylethylenediamines of the general formula in which R 1 and R 2 are alkyl radicals, at least one of which contains more than 1 carbon atom, preferably ethyl radicals, and the bromine atom is bonded in the o-, m- or p-position.
Das N-(2-Pyridyl)-1-p-brombenzyl-N',N'-dimethyläthylendiamin, also eine Verbindung der vorstehenden allgemeinen Formel, in der R, und R2 Methylreste bedeuten und das Brom in p-Stellung gebunden ist, ist als Antihistaminicum bekannt. Es ist auch bekannt, daß diese Verbindung eine lokalunästhetische Wirkung hat.The N- (2-pyridyl) -1-p-bromobenzyl-N ', N'-dimethylethylenediamine, that is a compound of the above general formula in which R 1 and R 2 are methyl radicals mean and the bromine is bound in the p-position, is known as an antihistamine. It is also known that this compound has a local unaesthetic effect.
Es wurde nun gefunden, daß gegenüber diesem bekannten Pyridyl-brombenzyl-dialkyl-äthylendiamin die neuen Verbindungen der allgemeinen Formel eine wesentlich verstärkte lokalunästhetische Wirkung bei abgeschwächter Antihistaminaktivität aufweisen. Dieses Verhalten ist besonders für die Diä thylderivate kennzeichnend, also Verbindungen der allgemeinen Formel, in denen R, und R2 Äthylreste bedeuten. Beispielsweise ist die lokalunästhetische Wirkung des N-(2-Pyridyl)-\r-mbrombenzyl-N',N'-diätliyl-ätliylendiamins 5,-19mal so groß wie die des 1>-Aminobenzoesäure-cliäthylaminoätliylesters.It has now been found that compared to this known pyridyl-bromobenzyl-dialkyl-ethylenediamine the new compounds of the general formula have a significantly increased local unaesthetic Have an effect on weakened antihistamine activity. This behavior is especially characteristic of the diethyl derivatives, ie compounds of the general Formula in which R, and R2 represent ethyl radicals. For example, the locally unaesthetic Effect of N- (2-pyridyl) - \ r-mbrombenzyl-N ', N'-dietliyl-ethylenediamine 5, -19 times as large as that of the 1> -aminobenzoic acid-cliäthylaminoätliylester.
Dieses Ergebnis ist überraschend, da nach in der Literatur geäußerten
Anschauungen angenommen werden konnte, daß die lokalunästhetische und die Antiliistaminwirkung
miteinander parallel gehen. Demgegenüber wurde gefunden, daß durch eine solche Substitution,
wie sie in den Erzeugnissen des vorliegenden Verfahrens vorhanden ist, eine Verstärkung
der Lokalan'istliesie bei gleichzeitiger Abschwächung der Histaminolyse zu erreichen
ist. Der pharmakologische Vergleich der Diä thylverbindungen mit (lern bekannten
N-(2-Pyrici},1)-N-pbromben7,yl-N',N'-dimethyl-ätliylendiamin (Hibernon) ergab:
Ein 2-(f-Diulkylamino-ätliylamino)-pyridin, in dem mindestens ein \-ständiger Alkylrest mehr als 1 Kohlenstoffatom enthält, wird mit einem Ester, besonders dem Bromwasserstoffsäureester, eines Brombenzylalkoliols unter Verwendung eines Alkaliamids als Kondensationsmittel umgesetzt.A 2- (f-Diulkylamino-ätliylamino) -pyridin, in which at least one the alkyl radical containing more than 1 carbon atom is combined with an ester, especially the hydrobromic acid ester, a bromobenzyl alcohol using an alkali amide implemented as a condensing agent.
