Die erfindungsgeraäßen Verbindungen sind wertvolle Heilmittel und zeichnen sich u.a. durch eine ausgeprägte sympathikomimetische Wirkung bzw. Herz- und Kreislaufwirkung aus.The compounds according to the invention are valuable medicinal products and are characterized, among other things, by a pronounced sympathomimetic Effect or cardiovascular effects.
Die folgenden Beispiele erläutern die Erfindung, ohne sie dadurch einzuschränken.The following examples illustrate the invention without thereby limiting it.
Beispiel 1: 27,27 g Chlorhydroxypropyltheophyllin und 16,65 g Norephedrin werden in der Hitze in i-Propanol gelöst. Man fügt dann langsam eine Aufschlämmung von 4,0 g Atznatron in i-Propanol hinzu. Nach erfolgter Zugabe wird noch 3 Stunden am Rückfluß erhitzt.Example 1: 27.27 g of chlorohydroxypropyl theophylline and 16.65 g of norephedrine are dissolved in i-propanol while hot. Man then slowly add a slurry of 4.0 g of caustic soda in i-propanol added. After the addition is complete, the mixture is refluxed for a further 3 hours.
Das ausgeschiedene NaCl wird abfiltriert und das Filtrat eingeengt. Der Rückstand wird aus verdünntem Äthanol umkristallisiert. Die Rohausbeute an Norephedrin-N-hydroxy-propyltheophyllin beträgt 84 %. The precipitated NaCl is filtered off and the filtrate is concentrated. The residue is recrystallized from dilute ethanol. The crude yield of norephedrine-N-hydroxy-propyltheophylline is 84 %.
Beispiel 2: 15,12g d,l-Norephedrin und 27,27 g Chlorhydroxypropyltheophyllin werden in 60 ml Xylol in der Hitze gelöst und 6 Stunden am Rückfluß erhitzt. Das Xylol wird abdestilliert und der Rückstand so lange mit Aceton gekocht, bis die gesamte Masse als weißes Pulver vorliegt und im Dünnschichtchromatogramm keine Ausgangsstoffe mehr nachweisbar sind. Der Rückstand wird aus Äthanol-Aceton umkristallisiert. Ausbeute: 35,5 g Korephedrin-N-hydroxypropyltheophyllin-HCl, Fp. 208 - 2220C.Example 2: 15.12 g of d, l-norephedrine and 27.27 g of chlorohydroxypropyl theophylline are dissolved in 60 ml of xylene in the heat and refluxed for 6 hours. The xylene is distilled off and the residue is boiled with acetone until the entire mass is present as a white powder and no more starting materials can be detected in the thin-layer chromatogram. The residue is recrystallized from ethanol-acetone. Yield: 35.5 g Korephedrin-N-hydroxypropyltheophyllin-HCl, mp 208-222 0 C..

Beispiel 3: 27,27 g Chlorhydroxypropyltheophyllin und 38,75 g Norephedrinhydroxypropyltheophyllin werden analog Beispiel 1 mit 4,0 g Ätznatron in der Hitze in Anwesenheit von i-Propanol als Lösungsmittel umgesetzt. Man erhält das Norephedrin-N-dihydroxypropyltheophyllin in 75 liger Ausbeute. Beispiel 4: 13,64 g Chlorhydroxypropyltheophyllin und 8,71 g liphedrin mit 1/2 Mol Kristallwasser in 150 ml i-Propanol werden in der Hitze gelöst, worauf unter Sieden und Rühren während 1 1/2 Stunden 2,0 g NaOH, aufgeschlammt in i-Propanol, zugegeben werden. Dann wird 3 Stunden lang am Rückfluß erhitzt. Die Reaktionsmischung wird noch heiß vom Natriumchlorid filtriert; das Filtrat wird im Vakuum eingedampft. Die erstarrte Schmelze wird zerrieben, mit Äther extrahiert und dann der Äther im Vakuum abgedampft. Die Rohausbeute beträgt 90,1 %. Beispiel 5: 18,97 g djl-m-Hydroxyphenyl-i-amino^-äthanol-HCl werden unter Stickstoffschutz in die Base übergeführt. Man erhält 13,5 g freie Base in Form des Hydrats. Davon setzt man 8,56 g mit 13,64 g Chlorhydroxypropyltheophyllin in Gegenwart von 10,37 g Kaliumcarbonat wasserfrei in 50 ml N,N-Dimethylformamid unter Stickstoffschutz bei 130 - 1500C um. Nach 12 Stunden ist die Reaktion beendet. Man filtriert ab, engt im Vakuum ein, führt in das Hydrochlorid über und kristallisiert dieses aus Äthanol-Aceton um. Man erhält 10,6 g 7-[ß-(ß'-Phenyl-ß'-hydroxy-äthylamino)-hydroxypropyli-theophyllin-HCl. Example 3: 27.27 g of chlorohydroxypropyl theophylline and 38.75 g of norephedrine hydroxypropyl theophylline are reacted analogously to Example 1 with 4.0 g of caustic soda in the heat in the presence of i-propanol as solvent. The norephedrine-N-dihydroxypropyltheophylline is obtained in a yield of 75%. Example 4: 13.64 g of chlorohydroxypropyltheophylline and 8.71 g of liphedrin with 1/2 mol of water of crystallization in 150 ml of i-propanol are dissolved in the heat , whereupon 2.0 g of NaOH are slurried with boiling and stirring for 1 1/2 hours in i-propanol. It is then refluxed for 3 hours. The reaction mixture is filtered off from the sodium chloride while it is still hot; the filtrate is evaporated in vacuo. The solidified melt is triturated, extracted with ether and then the ether is evaporated in vacuo. The crude yield is 90.1 %. Example 5: 18.97 g of djl-m-hydroxyphenyl-i-amino ^ -ethanol-HCl are converted into the base under nitrogen protection. 13.5 g of free base are obtained in the form of the hydrate. Of this, 8.56 g are reacted with 13.64 g of chlorohydroxypropyl theophylline in the presence of 10.37 g of anhydrous potassium carbonate in 50 ml of N, N-dimethylformamide at 130-150 ° C. under nitrogen protection. The reaction has ended after 12 hours. It is filtered off, concentrated in vacuo, converted into the hydrochloride and this is recrystallized from ethanol-acetone. 10.6 g of 7- [β- (β'-phenyl-β'-hydroxy-ethylamino) -hydroxypropyli-theophylline-HCl are obtained.
