Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung wertvoller Derivate des 2-Oxo-1,2-dihydrochinolins der Formel
EMI1.1
worin R Wasserstoff oder niederes Alkyl, Rl Wasserstoff, niederes Alkyl, Alkenyl, Aralkyl, Aryl, Dialkylaminoalkyl, wobei die am N-Atom stehenden Alkylgruppen direkt oder über ein Heteroatom zu einem Fünf-, Sechs- oder Siebenring verbunden sein können, R2 Wasserstoff, niederes Alkyl oder Aryl, R3 niederes Alkoxy, X Wasserstoff, Halogen oder niederes Alkyl, m die Zahlen 1, 2 oder 3, Al und A2 einen geradkettigen oder verzweigten Alkylenrest mit 2 bis 4 C-Atomen und Y Wasserstoff, eine Hydroxylgruppe oder den Rest
EMI1.2
bedeuten.
Das erfindungsgemässe Verfahren zur Herstellung der genannten Derivate ist nun dadurch gekennzeichnet, dass man Derivate des 7-Hydroxy-2-oxo- 1, 2-dihydro-chinolins der Formel
EMI1.3
mit einem Piperazinderivat der Formel
EMI1.4
oder dessen Hydrochlorid, worin Hal für ein Halogenatom steht, gegebenenfalls in Anwesenheit eines säurebindenden Mittels, umsetzt.
Als Niederalkylreste R, R1, R2 und X und Alkoxyreste R3 kommen insbesondere solche mit 1 bis 4 C-Atomen in Frage.
Die Verbindung der Formel I kann, falls Y die OH-Gruppe bedeutet, mit einer Alkoxybenzoesäure der Formel
EMI1.5
worin R3 und m die angegebene Bedeutung haben, oder mit einem funktionellen Derivat, z.B. mit 3,4,5-Trimethoxyben zoylchlorid, acyliert werden.
Die erfindungsgemäss herstellbaren Derivate des 2-Oxo1,2-dihydro-chinolins sind wertvolle Arzneimittel; sie besitzen z.B. eine spezifische, coronargefässerweiternde Wirkung und sind in dieser Hinsicht bekannten Stoffen dieser Art überlegen.
Ihre Salze sind farblose, kristalline, in Wasser leicht lösliche Substanzen.
Beispiel
23,1 g (0,1 Mol) 3 -n-Butyl-4-methyl-7-hydroxy2-oxo-1 ,2-dihydro-chinolin werden unter Rühren in 220 ml Dimethylsulfoxyd gelöst und mit 33,6 g (0,3 Mol) Kalium-tert.-butylat versetzt. Diese Suspension wird 15 Min. bei Zimmertemperatur gerührt und dann portionsweise mit 48,7 g (0,1 Mol) 1-(P-3,4,5 -Tnmethoxybenzoxyäthyl)-4- (y-chlor- ss-hydroxypropyl)-piperazin-dihydrochlorid (hergestellt durch Umsetzung des N-(ss-3,4,5-Trimethoxy-benzoxyäthyl)-piperazins mit Epichlorhydrin) versetzt. Anschliessend rührt man 12 Stunden bei Zimmertemperatur und giesst dann das Reaktionsgemisch in Wasser. Das sich ölig abscheidende Reaktionsprodukt nimmt man in Essigester auf und wäscht einige Male mit verdünnter Natronlauge. Dann wird die Essigester-Lösung über geglühtem Natriumsulfat getrocknet.
Durch Einleiten von trockenem Chlorwasserstoff-Gas erhält man das Dihydrochlorind des 3-n-Butyl-4-methyl-7- {γ-[4'-(ss-3,4,5- trimethoxybenzoxyäthyl)-piperazino[1]]- l-hydroxypropoxy}-2-oxo- 1,2-dihydrochinolins in Form farbloser Nadeln vom Zers.P. 1800.
Ausbeute: 41 g = 60% der Theorie.

This suspension is stirred for 15 minutes at room temperature and then mixed in portions with 48.7 g (0.1 mol) of 1- (P-3,4,5-methoxybenzoxyethyl) -4- (γ-chloro-ss-hydroxypropyl) piperazine Dihydrochloride (prepared by reacting N- (ss-3,4,5-trimethoxy-benzoxyethyl) piperazine with epichlorohydrin). The mixture is then stirred for 12 hours at room temperature and the reaction mixture is then poured into water. The oily reaction product is taken up in ethyl acetate and washed a few times with dilute sodium hydroxide solution. Then the ethyl acetate solution is dried over calcined sodium sulfate.
The dihydrochloride of 3-n-butyl-4-methyl-7- {γ - [4 '- (ss-3,4,5-trimethoxybenzoxyethyl) -piperazino [1]] - is obtained by introducing dry hydrogen chloride gas. l-hydroxypropoxy} -2-oxo-1,2-dihydroquinolines in the form of colorless needles from Zers.P. 1800.
