Description
Gegenstand der vorliegenden Erfindung sind die CGRP-Antagonisten der allgemeinen Formel deren Tautomere, deren Diastereomere, deren Enantiomere, deren Hydrate, deren Gemische und deren Salze sowie die Hydrate der Salze, insbesondere deren physiologisch verträgliche Salze mit anorganischen oder organischen Säuren, diese Verbindungen enthaltende Arzneimittel, deren Verwendung und Verfahren zu ihrer Herstellung.The present invention relates to the CGRP antagonists of the general formula their tautomers, their diastereomers, their enantiomers, their hydrates, their mixtures and their salts, and the hydrates of the salts, in particular their physiologically acceptable salts with inorganic or organic acids, medicaments containing these compounds, their use and processes for their preparation.

Formel die Gruppeeinen Rest der Formel -NR2R3 einen Rest der
Formel In the above general formula (I)
A is a radical of the formula the group a remainder of the formula -NR 2 R 3 is a radical of the formula
Besonders bevorzugte Verbindungen der obigen allgemeinen Formel (I) sind beispielsweise folgende: deren Tautomere, deren Diastereomere, deren Enantiomere, deren Hydrate, deren Gemische und deren Salze sowie die Hydrate der Salze.Particularly preferred compounds of the above general formula (I) are, for example, the following: their tautomers, their diastereomers, their enantiomers, their hydrates, their mixtures and their salts, and the hydrates of the salts.
Die Verbindungen der allgemeinen Formel (I) werden nach prinzipiell bekannten Methoden hergestellt. Die folgenden Verfahren haben sich zur Herstellung der erfindungsgemäßen Verbindungen der allgemeinen Formel (I) besonders bewährt:
- (a) Zur Herstellung von Verbindungen der allgemeinen Formel in der A und R1 bis R3 wie eingangs erwähnt definiert sind: Umsetzung eines Piperidins der allgemeinen Formel in der R1 wie eingangs erwähnt definiert ist, mit einem Kohlensäurederivat der allgemeinen Formel in der G eine nucleofuge Gruppe, die gleich oder verschieden sein kann, bevorzugt das Chloratom, die p-Nitrophenoxy- oder Trichlormethoxy-Gruppe, bedeutet, und mit einer Verbindung der allgemeinen Formel in der A, R2 und R3 wie eingangs erwähnt definiert sind, mit der Maßgabe, dass R2 und R3 keine weitere freie, ungeschützte, primäre oder sekundäre aliphatische Aminofunktion enthalten. Die im Prinzip zweistufigen Reaktionen werden in der Regel als Eintopfverfahren durchgeführt, und zwar bevorzugt in der Weise, dass man in der ersten Stufe eine der beiden Komponenten (II) oder (IV) mit äquimolaren Mengen des Kohlensäurederivates der allgemeinen Formel (III) in einem geeigneten Lösemittel bei tieferer Temperatur zur Reaktion bringt, anschließend wenigstens äquimolare Mengen der anderen Komponente (II) oder (IV) zugibt und die Umsetzung bei höherer Temperatur beendet. Die Umsetzungen mit Bis-(trichlormethyl)-carbonat werden bevorzugt in Gegenwart von wenigstens 2 Äquivalenten (bezogen auf Bis-(trichlormethyl)-carbonat) einer tertiären Base, beispielsweise von Triethylamin, N-Ethyldiisopropylamin, Pyridin, 1,5-Diaza-bicyclo-[4,3,0]-non-5-en, 1,4-Diazabicyclo-[2,2,2]octan oder 1,8-Diazabicyclo-[5,4,0]-un-dec-7-en, durchgeführt. Als Lösungsmittel, die wasserfrei sein sollten, kommen beispielsweise Tetrahydrofuran, Dioxan, Dimethylformamid, Dimethylacetamid, N-Methyl-2-pyrrolidon, 1,3-Dimethyl-2-imidazolidinon oder Acetonitril in Betracht, bei Verwendung von Bis-(trichlormethyl)-carbonat als Carbonylkomponente werden wasserfreie Chlorkohlenwasserstoffe, beispielsweise Dichlormethan, 1,2-Dichlorethan oder Trichlorethylen, bevorzugt. Die Reaktionstemperaturen liegen für die erste Reaktionsstufe zwischen –30°C und +25°C, bevorzugt –5°C und +10°C, für die zweite Reaktionsstufe zwischen +15°C und der Siedetemperatur des verwendeten Lösemittels, bevorzugt zwischen +20°C und +70°C (Siehe auch: H. A. Staab und W. Rohr, "Synthesen mit heterocyclischen Amiden (Azoliden)", Neuere Methoden der Präparativen Organischen Chemie, Band V, S. 53-93, Verlag Chemie, Weinheim/Bergstr., 1967; P. Majer und R.S. Randad, J. Org. Chem. 59, S. 1937-1938 (1994); K. Takeda, Y. Akagi, A. Saiki, T. Sukahara und H. Ogura, Tetrahedron Letters 24 (42), 4569-4572 (1983); S.R. Sandler und W. Karo in "Organic Functional Group Preparations", Vol. II, S. 223-245, Academis Press, New York 1971).
- (b) Zur Herstellung von Verbindungen der allgemeinen Formel in der A und R1 bis R3 wie eingangs erwähnt definiert sind: Kupplung einer Carbonsäure der allgemeinen Formel in der A und R1 wie eingangs erwähnt definiert sind, mit einem Amin der allgemeinen Formel HNR2R3, in der R2 und R3 wie eingangs erwähnt definiert sind, mit der Maßgabe, dass sie keine freie weitere ungeschützte primäre oder sekundäre aliphatische Aminofunktion enthalten. Eine gegebenenfalls in dem Rest -NR2R3 zusätzlich vorhandene primäre oder sekundäre Aminofunktion wird jeweils mit einer geeigneten Schutzgruppe versehen. Die Kupplung wird bevorzugt unter Verwendung von aus der Peptidchemie bekannten Verfahren (siehe z.B. Houben-Weyl, Methoden der Organischen Chemie, Bd. 15/2) durchgeführt, wobei zum Beispiel Carbodiimide, wie z.B. Dicyclohexylcarbodiimid (DCC), Diisopropylcarbodiimid (DIC) oder Ethyl-(3-dimethylamino-propyl)-carbodiimid, O-(1H-Benzotriazol-1-yl)-N,N-N',N'-tetramethyluronium-hexafluorphosphat (HBTU) oder -tetrafluorborat (TBTU) oder 1H-Benzotriazol-1-yl-oxy-tris-(dimethylamino)-phosphoniumhexafluorphosphat (BOP) eingesetzt werden. Durch Zugabe von 1-Hydroxybenzotriazol (HOBt) oder von 3-Hydroxy-4-oxo-3,4-dihydro-1,2,3-benzotriazin (HOOBt) kann die Reaktionsgeschwindigkeit gesteigert werden. Die Kupplungen werden normalerweise mit äquimolaren Anteilen der Kupplungskomponenten sowie des Kupplungsreagenz in Lösungsmitteln wie Dichlormethan, Tetrahydrofuran, Acetonitril, Dimethylformamid (DMF), Dimethylacetamid (DMA), N-Methylpyrrolidon (NMP) oder Gemischen aus diesen und bei Temperaturen zwischen –30 und +30°C, bevorzugt –20 und +25°C, durchgeführt. Sofern erforderlich wird als zusätzliche Hilfsbase N-Ethyldiisopropylamin (DIEA) (Hünig-Base) bevorzugt. Als weiteres Kupplungsverfahren zur Synthese von Verbindungen der allgemeinen Formel (I) wird das sogenannte "Anhydridverfahren" (siehe auch: M. Bodanszky, "Peptide Chemistry", Springer-Verlag 1988, S. 58-59; M. Bodanszky, "Principles of Peptide Synthesis", Springer-Verlag 1984, S. 21-27) eingesetzt. Bevorzugt wird das "gemischte Anhydridverfahren" in der Variante nach Vaughan (J.R. Vaughan Jr., J. Amer. Chem.Soc. 73, 3547 (1951)), bei der unter Verwendung von Chlorkohlensäureisobutylester in Gegenwart von Basen, wie 4-Methylmorpholin oder 4-Ethylmorpholin, das gemischte Anhydrid aus der zu kuppelnden Carbonsäure der allgemeinen Formel (V) und dem Kohlensäuremonoisobutylester erhalten wird. Die Herstellung dieses gemischten Anhydrids und die Kupplung mit den Aminen der allgemeinen Formel HNR2R3 erfolgt im Eintopfverfahren, unter Verwendung der vorstehend genannten Lösemittel und bei Temperaturen zwischen –20°C und +25°C, bevorzugt zwischen 0°C und +25°C.
