Description
Verfahren zur Darstellung eines Aminoalkohols der Chinolinreihe. Es wurde gefunden, dass man zu einem Aminoalkohol der 2-Phenylchinolini-eihe ge langen kann, indem man 2-Phenyl-6-äthoxy- chinolyl-4-methylketon an der Methylgruppe halogeniert,
das entstehende 2-Phenyl-6-äth- oxychinolyl-4-halogenmethylketon durch Um setzung mit Dimethylamin in das 2-Phenyl- 6 - äthoxychiriolyl - 4 - dirnethylamirioäthanon überführt und dieses zu 2-Phenyl-6-äthoxy- chinolyl-4-dimethylaminoäthariol reduziert.
Das 2-Pheriyl-6-äthoxychinolyl-4-dimethyl- aminoäthanol vorn der Formel
EMI0001.0020
bildet farblose Nädelchen vom Smp. 95 . Das Dichlorhydrat der Base besteht aus hellgelben Kristallen und schmilzt bei etwa 210' unter Zersetzung. In Wasser gelöst zeigt das Dichlorhydrat schön blaue Fluores zenz. Wie bei Chinin verschwindet letztere auf Zusatz von Halogenwasserstoff, nicht aber von andern Säuren. Mit Chinin bat die Base auch die Thalleiochinreaktion gemein.
Die neue Verbindung soll zu therapeu tischen Zwecken Verwendung finden. <I>Beispiel</I> 2-Pltenyl-6-lithoxychirtolyt-4-Lrognmethydketon: 5,8 Teile 2-Phenyl-6-ätlioxychiriolyl-4- methylketon (gelbe Kristalle vom Smp. <B>107",
</B> in üblicher Weise erhalten durch Kondensation von 2-Plienyl-6-äthogychinolin-4-karborisäure- ätbylestermit Essigsäureäthylester undKohleri- säureabspaltung aus dem entstandenen 2- Phenyl - 6-äthoxy- 4 - chirioloylessigsäLireäthyl- est.er vom Smp. 98-99 oder aus 2-Phenyl-6- äthoxy-4-cyanehinolin nach der Grignard'schen Reaktion)
werden mit 240 Teilen konzentrier ter Bromwasserstoffsäure auf 70-75 erwärmt; dann werden 3,2 Teile Brom, gelöst in 10 Teilen Bromwasserstoffsäure, unter lebhaftem Rühren zugetropft. Das bromwasserstoffsaure Salz des Bromketons wird nach dem Eikalten abfiltriert und mit Alkoholäther gewaschen.
Das 2-Phenyl-6-äthoxychinolyl-4-bromme- thylketonbromhydrat bildet intensiv gelbe Kristalle, welche bei<B>207'</B> unter Zersetzung schmelzen. Die freie Base, gelbe Kristalle, schmilzt bei<B>1290.</B>
2-Plzerayl-6-äthoxychinolyl-4-dzniethylami-rao- ä-th.anon: Zu 2,7 Teilen Dimethylamin (3 Mol.), gelöst in 60 Teilen Benzol, gibt man 9 Teile ,\3-Phenyl-6- äthoxy-chinolyl-4-brommethylke- tonbromhydrat (1 Mol.). Man schüttelt, bis das gelbe Bromketon verschwunden ist, lässt kurze Zeit stehen und filtriert vom ausge schiedenen Dimethylaminbromhydrat ab.
Die gelbe benzolische Lösung wird mit der berech neten Menge wässeriger Bromwasserstoffsäure behandelt. Es scheidet sich das in Wasser schwer lösliche Monobromhydrat des 2-Phenyl- 6-äthoxychinolyl-4-dimethylaminoäthanons in gelben Kristallen aus. Sie lassen sich aus wässerigem Alkohol umkristallisieren und schmelzen dann bei<B>2300</B> unter Zersetzung.
2-Plaereyl-6-äthoxychinolyl-4-dimethylramino- ätha7tol: a) 1 Teil 2-Phenyl-6-äthoxychinolyl-4- dimethylainirio-äthanonbromhydrat wird in 10 Vol. Teilen Alkohol mit der äquivalenten Menge Natriumäthylat versetzt, wobei das Salz in Lösung geht, indem sich die freie Base bildet. Nun wird bei Gegenwart von Nickel katalysator mit Wasserstoff geschüttelt, bis die berechnete Menge aufgenommen ist.
Es wird filtriert, der Alkohol vertrieben und die Base in Äther aufgenommen. Sie wird zweck mässig über ihr Dichlorhydrat gereinigt.
b) 1 Teil bromwasserstoffsaures 2-Phenyl- 6 - äthoxychinolyl- 4- dirnethylamino-äthanon wird in Wasser suspendiert und auf Zusatz von 1 Mol. Salzsäure mit Wasserstoff bei Gegenwart von Palladium geschüttelt. Nach Aufnahme der berechneten Menge Wasser stoff wird das Palladium entfernt und die Base mit Soda in Freiheit gesetzt. Durch Kristallisation aus Äther unter Zusatz von Petroläther erhält man sie in farblosen, rosetten- artig angeordneten Nädelchen.
An Stelle des Palladiums können auch andere Kontaktmetalle, wie Platin etc., ver wendet werden. Ebenso lässt sich die Reduk tion mit Metallen, wie Zink oder Eisen, in Ameisensäure oder in alkoholisch-alkalischer Lösung mit Aluminium oder Zink ausführen. Schliesslich kann die Isolierung des Amino- ketons umgangen werden, indem die berizo- lische Lösung der aus dem Bromketon erhal tenen Amirioketonbase z. B. mit Ameisensäure ausgeschüttelt und mit Zink reduziert wird.
Process for the preparation of a quinoline series amino alcohol. It has been found that an amino alcohol of the 2-phenylquinolini series can be obtained by halogenating 2-phenyl-6-ethoxy-quinolyl-4-methyl ketone on the methyl group,
the resulting 2-phenyl-6-ethoxyquinolyl-4-halomethyl ketone is converted into 2-phenyl-6-ethoxychiriolyl-4-dirnethylamirioethanol by reaction with dimethylamine and this is converted to 2-phenyl-6-ethoxyquinolyl-4-dimethylaminoethariol reduced.
The 2-Pheriyl-6-ethoxyquinolyl-4-dimethyl-aminoethanol from the formula
EMI0001.0020
forms colorless needles with a melting point of 95. The dichlorohydrate of the base consists of pale yellow crystals and melts at about 210 ° with decomposition. When dissolved in water, the dichlorohydrate shows a beautiful blue fluorescence. As with quinine, the latter disappears on the addition of hydrogen halide, but not of other acids. The base also had the thalleiochine reaction in common with quinine.
The new connection is intended to be used for therapeutic purposes. <I> Example </I> 2-Pltenyl-6-lithoxychirtolyt-4-Lrognmethydketon: 5.8 parts of 2-phenyl-6-ätlioxychiriolyl-4-methylketone (yellow crystals with melting point <B> 107 ",
Obtained in the usual way by condensation of 2-plienyl-6-ethogyquinoline-4-carboric acid ethyl ester with ethyl acetate and carbonic acid elimination from the 2-phenyl-6-ethoxy-4-chirioloyl-acetic acid ethyl ester of melting point 98 -99 or from 2-phenyl-6-ethoxy-4-cyanoquinoline according to the Grignard reaction)
are heated to 70-75 with 240 parts of concentrated hydrobromic acid; then 3.2 parts of bromine, dissolved in 10 parts of hydrobromic acid, are added dropwise with vigorous stirring. The hydrobromic acid salt of the bromine ketone is filtered off after the ice cold and washed with alcohol ether.
The 2-phenyl-6-ethoxyquinolyl-4-bromomethyl ketone bromohydrate forms intensely yellow crystals, which melt at <B> 207 '</B> with decomposition. The free base, yellow crystals, melts at <B> 1290. </B>
2-Plzerayl-6-ethoxyquinolyl-4-dzniethylami-rao-th.anon: To 2.7 parts of dimethylamine (3 mol.), Dissolved in 60 parts of benzene, are added 9 parts of \ 3-phenyl-6- ethoxy-quinolyl-4-bromomethyl ketone bromohydrate (1 mol.). It is shaken until the yellow bromoketone has disappeared, left to stand for a short time and the separated dimethylamine bromohydrate is filtered off.
The yellow benzene solution is treated with the calculated amount of aqueous hydrobromic acid. The sparingly water-soluble monobromo hydrate of 2-phenyl-6-ethoxyquinolyl-4-dimethylaminoethanone separates out in yellow crystals. They can be recrystallized from aqueous alcohol and then melt at <B> 2300 </B> with decomposition.
2-Plaereyl-6-ethoxyquinolyl-4-dimethylramino-ätha7tol: a) 1 part of 2-phenyl-6-ethoxyquinolyl-4-dimethylainirio-ethanone bromohydrate is added in 10 parts by volume of alcohol with the equivalent amount of sodium ethylate, the salt in solution goes by forming the free base. Now the catalyst is shaken with hydrogen in the presence of nickel until the calculated amount is absorbed.
It is filtered, the alcohol expelled and the base taken up in ether. It is conveniently cleaned using its dichlorohydrate.
b) 1 part of hydrobromic acid 2-phenyl-6-ethoxyquinolyl-4-dirnethylamino-ethanone is suspended in water and, upon addition of 1 mol. Hydrochloric acid, shaken with hydrogen in the presence of palladium. After the calculated amount of hydrogen has been taken up, the palladium is removed and the base is released with soda. Crystallization from ether with the addition of petroleum ether gives them colorless, rosette-like needles.
Instead of palladium, other contact metals such as platinum etc. can also be used. The reduction can also be carried out with metals such as zinc or iron, in formic acid or in an alcoholic-alkaline solution with aluminum or zinc. Finally, the isolation of the amino ketone can be circumvented by adding the berizolic solution of the amino ketone base obtained from the bromine ketone, e.g. B. shaken out with formic acid and reduced with zinc.
