Description
Verfahren zur Darstellung eines basischen Phenolalkyläthers.
EMI0001.0002
Im <SEP> Hauptpatent <SEP> ist <SEP> ein <SEP> Verfahren <SEP> zur
<tb> Darstellung <SEP> eines <SEP> neuen <SEP> Phenolalkyläthers
<tb> (2. <SEP> 6-Dimethoxy-4-alilyl-phenyl-di.äthylamino ä:thyläther) <SEP> beschrieben.
<tb>
Fis <SEP> zeigte <SEP> sich <SEP> nun, <SEP> dass <SEP> man <SEP> -einen <SEP> neuen
<tb> Pheno#lalkyläther <SEP> erhält, <SEP> wenn <SEP> man <SEP> 5-Crotvl
<tb> guajacolearbonsäuremethylester <SEP> (OH, <SEP> 0 <SEP> CH.:
<tb> - <SEP> 2.3) <SEP> entsprechend <SEP> Odem <SEP> Verfahren <SEP> des
<tb> Hauptpatentes <SEP> mit <SEP> Diäthylaminoäthylchlorid
<tb> zum <SEP> 2-(co-Diäthylaminoäthoxy-)3-methoxy-5 crotylbenzoesäuremethylester <SEP> umsetzt.
<tb>
Das <SEP> Produkt <SEP> sohl <SEP> als <SEP> Lokalanästhetikum
EMI0001.0003
Verwendung <SEP> finden.
EMI0001.0004
<I>Beispiel:</I> 10 Gewichtsteile des Natriumsalzes vom 5- Crotyl-guajaeoleaTbonsäturemethylester (OH.
0 CH, = 2. 3) werden zusammen mit 10 Ge-- wichsteilen Diäthylaminoäthylchlorid einige Zeit erwärmt. Nach beendeter Umsetzung löst man das Reaktionsgemengs in verdünn ter Salzsäure, äthert aus und versetzt die ausgeätherte Flüssigkeit mit Natron-lange bis zur alkalischen Reaktion.
Das sich abschei- dende 01 wird abgetrennt, getrocknet und destilliert. Unter 2 mm Dxnxck siedet der so erhal tene 2-(co-Diäthylaminoäthnxy)-3-methoxy-5- crotyl-benzo,esäuremethylester von 200 bis 202 als schwaeh gelbgefärbtes 01.
Der neuen Verbindung kommt die folgende Struk turformel zu:
EMI0001.0036
Dass salzsaure Salz der Base schmilzt nach dem Umkristallisieren aus Aceton von 116 bis 118 .

In the <SEP> main patent <SEP> <SEP> is a <SEP> method <SEP> for
<tb> Representation <SEP> of a <SEP> new <SEP> phenol alkyl ether
<tb> (2. <SEP> 6-dimethoxy-4-alilyl-phenyl-diethylamino ä: ethyl ether) <SEP> described.
<tb>
Fis <SEP> <SEP> showed <SEP> now, <SEP> that <SEP> one <SEP> - a <SEP> new one
<tb> Phenolic alkyl ether <SEP> is obtained, <SEP> if <SEP> one <SEP> 5-Crotvl
<tb> guaiacolarboxylic acid methyl ester <SEP> (OH, <SEP> 0 <SEP> CH .:
<tb> - <SEP> 2.3) <SEP> according to <SEP> or <SEP> procedure <SEP> des
<tb> main patent <SEP> with <SEP> diethylaminoethyl chloride
<tb> to <SEP> 2- (co-diethylaminoethoxy-) 3-methoxy-5-crotylbenzoic acid methyl ester <SEP>.
<tb>
The <SEP> product <SEP> sole <SEP> as a <SEP> local anesthetic
EMI0001.0003
Find use <SEP>.
EMI0001.0004
<I> Example: </I> 10 parts by weight of the sodium salt of 5-crotyl-guajaeoleaTbonsäturemethylester (OH.
0 CH, = 2. 3) are heated for some time together with 10 parts by weight of diethylaminoethyl chloride. After the reaction has ended, the reaction mixture is dissolved in dilute hydrochloric acid, etherified and the etherified liquid is treated with sodium bicarbonate for a long time until an alkaline reaction occurs.
The oil which separates out is separated off, dried and distilled. The 2- (co-diethylaminoethyl) -3-methoxy-5-crotyl-benzo, methyl ester of 200 to 202 obtained in this way boils below 2 mm in diameter as a pale yellow-colored 01.
The new compound has the following structural formula:
EMI0001.0036
The hydrochloric acid salt of the base melts from 116 to 118 after recrystallization from acetone.
