Description
Foreliggende oppfinnelse angår en forbedret fremgangsmåte for fremstilling av visse forbindelser og (S)-l-fenyl-2-(2-pyridyl)etanamin og (S)-l-fenyl-2-(2-pyridyl)etanamin (S)-malatsalt fremstilt ved fremgangsmåten.
EP 0 633 879 Bl beskriver forbindelser som sies å ha en NMDA reseptor antagonist aktivitet. Forbindelsen kjent som (S)-l-fenyl-2-(2-pyridyl)etanamin er av spesielle interesse, særlig for behandling av slag. Imidlertid lider prosessen som beskrevet i EP 0 633 879 Bl for fremstilling av denne forbindelse, av visse mangler, for eksempel ved at den krever bruken av butyllitium som ikke er gunstig å anvende i stor målestokk.
Det er nå utviklet en ny fremgangsmåte for fremstilling av (S)-l-fenyl-2(2-pyridyl)etanamin som unngår behovet for anvendelse av butyllitium og som derfor er mer egnet for kommersiell anvendelse. Fordi prosessen ifølge oppfinnelsen eliminerer behovet for å anvende butyllitium har den derfor også den ytterligere fordel at den ikke lider under miljøproblemer i forbindelse med butanemisjonen. Videre er det overraskende funnet at fremgangsmåten ifølge oppfinnelsen kan gjennomføres med kun en katalytisk mengde base [i forhold til 2-pikolin med formel (II)] i stedet for en støkiometrisk mengde base som benyttet i EP 0 633 879 Bl. Totalt sett er derfor den her krevede prosess mer effektiv, sikrere, miljømessige gunstige og også rimeligere enn den ifølge EP 0 633 879 Bl.
I et første aspekt tilveiebringer oppfinnelsen derfor en fremgangsmåte for fremstilling av en forbindelse med formel (I) eller et farmasøytisk akseptabelt salt derav:
og som kjennetegnes ved at den omfatter: omsetning av en forbindelse med formel (II) med en forbindelse med formel (III):
i nærvær av et metallheksametyldisilazid og eventuelt derefter oppløsning av enantiomerene av forbindelse (I) og tildanning av et farmasøytisk akseptabelt salt.
En forbindelse med formel (III) kan fremstilles fra benzoaldehyd og et metallheksametyldisilazid, fortrinnsvis litiumheksametyldisilazid (LHMDS). Fortrinnsvis fremstilles forbindelsen med formel (III) ved redusert temperatur, det vil si under 35 °C og fortrinnsvis under 25 °C.
Reaksjonen mellom forbindelsene (II) og (HI) gjennomføres hensiktsmessig ved forhøyt temperatur, for eksempel rundt 40 °C. Reaksjonen kan gjennomføres i et inert opp-løsningsmiddel og fortrinnsvis i et eterisk oppløsningsmiddel som t-butylmetyleter eller helst tetrahydrofuran. Fortrinnsvis er metallheksametyldisilazidet litiumheksametyldisilazid (LHMDS) og denne base benyttes i en katalytisk mengde i forhold til 2-pikolin (2-metylpyridin) med formel (II), for eksempel rundt 10 mol%. Sur opparbeiding av reaksjonsblandingen gir den ønskede forbindelse med formel (I).
Forbindelsene som fremstilles ifølge oppfinnelsen kan danne farmasøytisk akseptable solvater og salter. Forbindelsene med formel (I) kan danne syreaddisjonssalter med syrer, for eksempel konvensjonelle, farmasøytiske akseptable salter med eple-, salt-, hydrobrom-, fosfor-, edikk-, fumar-, salisyl-, sitron-, melke-, mandel-, vin-, trifluoredikk- og metansulfonsyre. Foretrukne salter er malat- og hydrokloridsaltende.
Særlig foretrukne salter er de som kan fremstilles ved bruk av chirale syrer for å gi salter av en enkel enantiomer av forbindelse (I) som beskrevet i EP 0 691 957 Bl. Fortrinnsvis blir den racemiske forbindelse med formel (I) behandlet med (S)-eplesyre for å gi (S)-l-fenyl-2-(2-pyridyl)etanamin (S)-malat.
I et ytterligere aspekt tilveiebringer oppfinnelsen (S)-l-fenyl-2-(2-pyridyl)etanamin og salter derav, særlig (S)-malatsaltet, fremstilt ved bruk av den her beskrevne fremgangsmåte.
Oppfinnelsen skal illustreres ved hjelp av det følgende eksempel.
Eksempel
( S)- a- fenvl- 2- pvridinetanamin ( S)- malat
En oppløsning av litiumheksametyldisilazid (1100 ml av en 1,0 M oppløsning i tetrahydrofuran, 1,1 mol) ble dråpevis og under nitrogen og under avkjøling, satt til en omrørt oppløsning av benzaldehyd (102 ml, 1,0 mol) i 305 ml tetrahydrofuran mens temperaturen ble holdt under 25 °C. Den resulterende oppløsning ble omrørt ved 20 °C i 30 minutter før tilsetning av 2-pikolin (101 ml, 1,0 mol) i en porsjon fulgt av ytterligere 102 ml tetrahydrofuran. Reaksjonsblandingen ble så oppvarmet til 40 °C i løpet av 30 minutter og så holdt ved 40 °C i 90 minutter. Oppløsningen ble så avkjølt til 20 °C i løpet av 10 minutter og dråpevis satt til en oppløsning av konsentrert saltsyre og (420 ml, 5,0 mol) i 900 ml demineralisert vann under avkjøling for å holde temperaturen mellom 10 og 20 °C. Den resulterende blanding, (pH 1) ble omrørt ved 20 °C i 15 minutter hvoretter sjiktene ble separert. Den nedre vandige fase ble separert og vasket med 2 x 900 ml etylacetat og så gjort basisk ved tilsetning av en oppløsning av natrium-hydroksyd (200 g, 5,0 mol) i 830 ml demineralisert vann under avkjøling for å holde temperaturen i området 10 til 20 °C. Den resulterende blanding, (pH 12) ble så omrørt ved 20 °C i 15 minutter og så ekstrahert med 2 x 800 ml etylacetat. Etylacetatopp-løsningen ble så satt til en oppløsning av S-melkesyre (120,7 g 0,9 mol) i 1060 ml etanol, fulgt av poding med 0,2 g av tittelforbindelsen. Denne blanding ble omrørt i 30 minutter ved 20 °C og så avkjølt til 0 °C og omrørt i 20 timer ved 0 °C. Suspensjonen ble filtrert og vasket med 530 ml etanol og man oppnådde et hvitt faststoff som tørket i en vakuumovn ved 40 °C over natten for å gi 119,07 g tilsvarende 35,8% (S)-cc-fenyl-2-pyridinetanamin (S)-malat som et hvitt fast stoff, identiske med kjent materiale.
