Description

  

  Verfahren zur Herstellung von neuen 1-Phenoxy-2-hydroxy-3-alkylaminopropanen    Die Erfindung betrifft ein Verfahren zur Herstellung  von neuen racemischen oder optisch aktiven     1-Phenoxy-          2-hydroxy-3-alkylaminopropanen    der Formel I  
EMI0001.0002     
    und von deren Säureadditionssalzen.

    In dieser Formel bedeuten:  R eine Alkylgruppe mit 5 bis 8 Kohlenstoffatomen,  die mindestens ein direkt oder über eine Alkylenkette  von 1 bis 4 Kohlenstoffatomen an die Aminogruppe ge  bundenes quartäres Kohlenstoffatom enthält,  R1 Wasserstoff, ein Halogenatom, eine     Nitrilo-          gruppe    oder eine Alkyl- oder Alkoxygruppe mit 1 bis  4 C-Atomen und  R2 Wasserstoff, ein Halogenatom, eine Alkyl- oder  Alkoxygruppe mit 1 bis 4 C-Atomen oder zusammen  mit R1 eine 3,4-Methylendioxygruppe.  



  Das erfindungsgemässe Verfahren zur Herstellung  der Verbindungen der Formel I ist dadurch gekenn  zeichnet, dass man eine Verbindung der Formel II  
EMI0001.0005     
    reduziert.  Das für die Durchführung des     erfindungsgemässen     Verfahrens benötigte Ausgangsmaterial ist zum Teil  bereits bekannt, zum Teil kann es nach üblichen Ver  fahren gewonnen werden. Die Verbindung der Formel    II kann beispielsweise ausgehend von einem Phenol  bzw.

   Phenolat der Formel III  2  
EMI0001.0007     
    worin Kt Wasserstoff oder ein Kation, beispielsweise  ein Alkalimetallkation, bedeutet, erhalten werden, in  dem man die Verbindung der Formel III mit     Epi-          chlorhydrin    in ein Epoxyd der Formel IV  
EMI0001.0010     
    überführt und dieses mit einem Alkylamin der Formel V  NH2-R V  umsetzt.  



  Die erfindungsgemäss erhältlichen Verbindungen be  sitzen ein asymmetrisches C-Atom und kommen daher  als Racemat wie auch in Form der optischen Antipo  den vor. Letztere können ausser durch     Racematentren-          nung    mit üblichen Hilfssäuren wie     Dibenzoyl-D-Wein-          säure    oder D-3-Bromcampher-8-sulfonsäure auch durch  Einsetzen von optisch aktivem Ausgangsmaterial erhal  ten werden. Die erfindungsgemäss erhältlichen     1-Phen-          oxy-3-aminopropanole    der Formel I können in üblicher  Weise in ihre physiologisch verträglichen Säureaddi  tionssalze überführt werden.

   Geeignete Säuren sind  beispielsweise Salzsäure, Bromwasserstoffsäure, Schwe  felsäure, Methansulfonsäure, Maleinsäure, Essigsäure,      Oxalsäure, Milchsäure, Weinsäure oder     8-Chlortheo-          phyllin.     



  Die Verbindungen der Formel 1 bzw. deren physio  logisch verträglichen Säureadditionssalze haben im Tier  versuch an     Meerschweinchen        wertvolle    therapeutische,  insbesondere ss-adrenolytische Eigenschaften gezeigt und  können daher beispielsweise zur Behandlung oder Pro  phylaxe von Erkrankungen der Herzkranzgefässe und  zur Behandlung von Herzarrhythmien, insbesondere  von Tachycardien, in der Humanmedizin eingesetzt wer  den. Auch die blutdrucksenkenden Eigenschaften der  Verbindungen sind therapeutisch     interessant.     



  Die Einzeldosis der erfindungsgemäss hergestellten       Substanzen    liegt bei 1-300 mg; vorzugsweise 5-100 mg  (oral) bzw. 1-20 mg (parenteral).  



  Die galenische Verarbeitung der erfindungsgemäss  erhaltenen Verbindungen zu den üblichen Anwendungs  formen wie     Lösungen,    Emulsionen, Tabletten, Dragees  oder     Depotformen    kann in bekannter Weise unter  Heranziehung der dafür gebräuchlichen galenischen  Hilfs-, Träger-, Spreng-, Binde-, Überzugs- oder  Schmiermittel, Geschmacksstoffe, Süssungsmittel, Mit  tel zur Erzielung einer Depotwirkung oder Lösungs  vermittler geschehen. Die erfindungsgemäss erhaltenen  Verbindungen sind auch für die Kombination mit ande  ren pharmakodynamisch wirksamen Stoffen wie     Coro-          nardilatatoren    oder Sympathicomimetica geeignet.  



  Das folgende Beispiel dient zur näheren Erläute  rung der Erfindung.    <I>Beispiel</I>       1-(3'-Aminophenoxy)-2-hydroxy-3-(1,1-dimethylbutyl)-          aminopropan    - 2 HCl  7,1 g (0,024 Mol)     1-(3'-Nitrophenoxy)-2-hydroxy-          3-(1,1-dimethylbutylamino)-propan    werden in 50 ml  Methanol über Raney-Nickel bei 20  C hydriert. Nach  Aufnahme der theoretischen Wasserstoffmenge wird der  Katalysator abgetrennt, das Methanol abdestilliert und  der Rückstand nach Lösen in wenig Äthanol mit äthe  rischer HCl versetzt. Das kristallin ausfallende     Hydro-          chlorid    wird aus Äthanol unter Zugabe von etwas  Äther umkristallisiert.

   Ausbeute: 5,1 g, Fp.:       173-174     C.



  Process for the preparation of new 1-phenoxy-2-hydroxy-3-alkylaminopropanes The invention relates to a process for the preparation of new racemic or optically active 1-phenoxy-2-hydroxy-3-alkylaminopropanes of the formula I
EMI0001.0002
    and their acid addition salts.

    In this formula: R denotes an alkyl group with 5 to 8 carbon atoms which contains at least one quaternary carbon atom bonded directly or via an alkylene chain of 1 to 4 carbon atoms to the amino group, R1 hydrogen, a halogen atom, a nitrilo group or an alkyl or an alkoxy group with 1 to 4 carbon atoms and R2 hydrogen, a halogen atom, an alkyl or alkoxy group with 1 to 4 carbon atoms or, together with R1, a 3,4-methylenedioxy group.



  The process according to the invention for the preparation of the compounds of the formula I is characterized in that a compound of the formula II
EMI0001.0005
    reduced. Some of the starting material required for carrying out the process according to the invention is already known, and some can be obtained by conventional methods. The compound of the formula II can, for example, starting from a phenol or

   Phenolate of the formula III 2
EMI0001.0007
    wherein Kt is hydrogen or a cation, for example an alkali metal cation, can be obtained by converting the compound of the formula III with epichlorohydrin into an epoxide of the formula IV
EMI0001.0010
    transferred and this with an alkylamine of the formula V NH2-R V is reacted.



  The compounds obtainable according to the invention have an asymmetric carbon atom and therefore occur as a racemate as well as in the form of the optical antipodes. The latter can be obtained not only by resolution of the racemates with customary auxiliary acids such as dibenzoyl-D-tartaric acid or D-3-bromocamphor-8-sulfonic acid but also by using optically active starting material. The 1-phenoxy-3-aminopropanols of the formula I obtainable according to the invention can be converted into their physiologically tolerated acid addition salts in the customary manner.

   Suitable acids are, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, methanesulphonic acid, maleic acid, acetic acid, oxalic acid, lactic acid, tartaric acid or 8-chlorotheophylline.



  The compounds of formula 1 and their physiologically tolerable acid addition salts have shown valuable therapeutic, in particular ss-adrenolytic properties in animal experiments on guinea pigs and can therefore be used, for example, for the treatment or prophylaxis of diseases of the coronary arteries and for the treatment of cardiac arrhythmias, especially tachycardias, used in human medicine. The antihypertensive properties of the compounds are also of therapeutic interest.



  The single dose of the substances prepared according to the invention is 1-300 mg; preferably 5-100 mg (oral) or 1-20 mg (parenteral).



  The pharmaceutical processing of the compounds obtained according to the invention into the customary application forms such as solutions, emulsions, tablets, coated tablets or depot forms can be carried out in a known manner using the pharmaceutical auxiliaries, carriers, disintegrants, binders, coatings or lubricants, flavorings, which are customary for this , Sweeteners, means to achieve a depot effect or solubilizers happen. The compounds obtained according to the invention are also suitable for combination with other pharmacodynamically active substances such as coronary dilators or sympathomimetics.



  The following example serves to explain the invention in more detail. <I> Example </I> 1- (3'-aminophenoxy) -2-hydroxy-3- (1,1-dimethylbutyl) - aminopropane - 2 HCl 7.1 g (0.024 mol) 1- (3'-nitrophenoxy ) -2-hydroxy-3- (1,1-dimethylbutylamino) propane are hydrogenated in 50 ml of methanol over Raney nickel at 20.degree. After the theoretical amount of hydrogen has been absorbed, the catalyst is separated off, the methanol is distilled off and, after dissolving in a little ethanol, the residue is treated with ethereal HCl. The hydrochloride which precipitates in crystalline form is recrystallized from ethanol with the addition of a little ether.

   Yield: 5.1 g, m.p .: 173-174 C.
