Description
143343 i
Opfindelsen angår en analogifremgangsmåde til fremstilling af 3-substituerede 4-fenylpiperidiner med den i krav l's indledning viste almene formel (I) hvor R, R1 og X har de sammesteds angivne betydninger, eller optisk aktive former heraf eller salte af forbindelserne med farmaceutisk acceptable syrer,og fremgangsmåden er ejendommelig ved det i krav l's kendetegnende del angivne.
Eksempelvis kan alkylgrupperne være metyl, ætyl, propyl, isopropyl, n-butyl eller t-butyl, også når de indgår i alkyl-thio- og alkoxygrupper; alkynylgrupperne kan være ætynyl, propynyl eller butynyl og acylaminogrupperne acetylamino, propionylamino eller butyrylamino.
Halogensubstituenterne er fortrinsvis klor, brom eller fluor.
De saltdannende syrer kan være hvilke som helst af de sædvanlige farmaceutisk acceptable syrer.
De omhandlede, hidtil ukendte piperidinderivater har interessante farmakologiske egenskaber, der gør dem nyttige som antidepressive midler og anti-Parkinsom-midler. Specielt er forbindelserne, hvor R er fenyl, 4-metoxyfenyl og 1,3-benz-dioxolyl værdifulde i så henseende.
For tiden er de i klinikken mest anvendte antidepres-sive midler de tricykliske thymoleptica, fx imipramin og amitriptylin. De virker ved central potentiering af serotonin (5HT) og noradrenalin (NA) som en følge af hæmningen af nervecellernes genoptagning af disse stoffer.
En tilsvarende virkning af de ved den foreliggende fremgangsmåde fremstillede forbindelser er fastslået . ved bestemmelse af hæmningen af optagelse af 5 HT og NA in vitro under anvendelse af synaptosomer fremstillet fra forskellige regioner af rottehjerner. Nogle af forbindelserne, fx GF 32, GF 52 og Gf 57 (se omstående eksempler) er særlig kraftigt hæmmende for optagelsen af 5 HT, medens andre, fx GF 48 og Gf 49, virker stærkere hæmmende på optagelsen af NA. De kendte tricykliske thymoleptica påvirker de kardiovaskulære og perifere autonome nervesystemer og frembringer en lang række 2 149943 bivirkninger. Hjerteforstyrrelser og varierende grader af hypotension optræder forholdsvis hyppigt og kan være meget alvorlige.
Forbindelser fremstillet ved den foreliggende fremgangsmåde, fx GF 32, er mere aktive forstærkere af 5 HT end imipramin, men påvirker det kardiovaskulære system mindre end de mest almindelige tricykliske thymoleptica og har derfor ikke de nævnte, mere alvorlige bivirkninger. Disse forhold belyses nærmere i slutningen af beskrivelsen, efter eksemplerne .
Det skal desuden nævnes at der fra US patentskrift nr. 3.458.521 kendes piperidinderivater med en eventuelt substitueret fenylgruppe i stilling 4. Disse kendte forbindelser har analgetisk hovedvirkning med kun svag stimulerende virkning på centralnervesystemet, altså en helt anden virkning end de ved fremgangsmåden ifølge opfindelsen fremstillede forbindelser.
Fra norsk patentskrift nr. 125.928 kendes der piperidinderivater med en ætergruppe i stilling 3. De angives at have antidepressiv virkning, men har åbenbart ikke den anti-Parkin-son-virkning som knytter sig til de ved fremgangsmåden ifølge nærværende opfindelse fremstillede forbindelser.
Ingen af de nævnte kendte piperidinderivater har samtidig en eventuelt substitueret fenylgruppe i stilling 4 og en ætergruppe i stilling 3 og de adskiller sig derfor strukturelt fra de her omhandlede forbindelser.
De karbinoler, der anvendes som udgangsmateriale ved fremgangsmåden ifølge opfindelsen, kan fremstilles ved reduktion af forbindelser med den almene formel
Ncooch3 III
3 149843 hvor R1 og X har de ovenfor angivne betydninger, idet der til reduktionen fortrinsvis anvendes komplekse metalhydri-der, især litiumaluminiumhydrid.
Forbindelserne med formlen m kan fremstilles som angivet af J.T. Plati, A.K. Ingberman og W. Wenner {J. Org. Chem.
22 (1957) 261), der beskriver fremstillingen af den forbindelse, hvor X er hydrogen, og R1 er metyl, ved behandling af arecolin (metyl-1,2,5,6-tetrahydro-3-pyridinkarboxylat) med fenylmagniumbromid. På samme måde kan andre udgangsstoffer for de ønskede piperidinkarbinoler fremstilles fra den tilsvarende arecolinhomolog og X-fenylmagniumbromid. Reaktionen giver to isomerer, en cis-form (β-form) og en trans-form (α-form) (kulstofatomerne 3 og 4 i piperidinringen). Begge disse former kan igen opløses i en (+) og en (-) form.
Fremgangsmåden ifølge opfindelsen kan gennemføres efter forskellige metoder. Således illustreres metode a) ved følgende reaktionsskema:

Her giver o-karbinolerne α-ætere, medens 3-karbinolerne giver en blanding af a- og 6-ætere.
I regelen er en af de optisk aktive former af de her omhandlede forbindelser mere aktiv end den anden, og der kan 5 149343 da gennemføres en adskillelse mellem de to former som beskrevet i eksempel 3 i eksempeldelen af denne beskrivelse, eller adskillelsen kan ske på et tidligere stadium, før udgangsstoffets karbinolgruppe forætres.

A. 251 g metyl-4-(4-fluorfenyl)-1-metylnipecotinat (fremstil let som angivet af J.T. Plati), 8 g natriummetoxyd og 500 ml benzen koges under tilbagesvaling i 2 timer. Benzenopløsningen vaskes med koldt vand og inddampes, hvorved fås den rene α-ester. Denne opløses i en blanding af 320 ml vand og 540 ml koncentreret saltsyre, og opløsningen destilleres langsomt til fjernelse af metanol og inddampes til slut i vakuum til tørhed.
Til den faste inddampningsrest sættes i små portioner 400 ml thionylklorid. Blandingen henstår i 3 timer ved stuetemperatur, og der tilsættes tetraklorætan, hvorefter der inddampes i vakuum til tørhed. Det resulterende 4-(4-fluorfenyl)-N-metylnipe- cotinsyreklorid sættes i små portioner til en opløsning af 160 g 1498A3 11 (-)-menthol i 800 ml pyridin ved en temperatur på 0-5°C, og blandingen henstår ved stuetemperatur til næste dag. Så tilsættes isvand og 50%'s natriumhydroxyd, og blandingen ekstraheres med æter. Æteropløsningen tørres med vandfri magniumsulfat, filtreres og inddampes. Ved destillation i vakuum fås mentholesteren i et udbytte på 75-80%. Dens kogepunkt ved 0,05 mm kviksølvtryk er 165-170°C.
B. Til en opløsning af 365 g (1 mol) af den i trin A vundne mentholester i 1000 ml 99%'s ætanol sættes 93 g (0,55-mol)'48%'s hydrogenbromid. De udskilte krystaller frasuges og omkrystalliseres fra 96%'s ætanol, hvorved fås det rene hydrobromid med smp. 275-276°C. Af hydrobromidet frigøres basen og reduceres med litiumaluminium-hydrid, hvorved fås et næsten kvantitativt udbytte af (-)-a-4-(4- fluorfenyl)-3-hydroxymetyl-l-metylpiperidin./a7 -40° (c=s 5, ætanol) .
C, Til en opløsning af 170 ml thionylklorid i 600 ml kloroform sættes dråbevis en opløsning af 111,5 g (0,5 mol) af (-)-a-karbinolen ifølge trin B i 600 ml kloroform, idet temperaturen holdes under 10°C. Blandingen koges i 6 timer under tilbagesvaling på dampbad. Derefter inddampes i vakuum til tørhed, og der rystes i skilletragt med en kold 25%'s opløsning- af kaliumkarbonat og æter. Æterlaget tørres med vandfri magniumsulfat, inddampes og destilleres under reduceret tryk. Udbyttet af den derved vundne klorforbindelse med kogepunkt 81-83°C ved 0,05 mm kviksølvtryk er 90-95%, beregnet på karbinolen.
/£/ = -36° (c = 5, ætanol).
Til en opløsning af 4,63 g natrium i 125 ml metanol sættes 29 g 3,4-metylendioxyfenol og 41 g af klorforbindelsen. Blandingen omrøres og koges under tilbagesvaling i 16 timer. Efter fjernelse af opløsningsmidlet i vakuum hældes inddampningsresten i en blanding af 150 g is, 150 ml vand og 200 ml æter. Æterlaget fraskilles, og vandlaget ekstraheres med æter. De forenede æteropløsninger vaskes med vand og tørres med vandfri magniumsulfat, hvorefter æteren af-dampes. Inddampningsresten tritureres med 200 ml 99%’s alkohol og 11,5 ml koncentreret saltsyre, og der vindes 15,8 g (-)-a-4-(4-fluor-fenyl)-3-(1,3-benzdioxolyl-(5))-oxymetyl-l-metylpiperidin som hydro-klorid med smp. 230°C.
