Description
Foreliggende oppfinnelse angår en analogifremgangsmåte ved fremstilling av terapeutisk aktive forbindelser av generell . formel I:
hvor Am er amino eller dialkylamino hvor alkylgruppen har 1-4 carbonatomer, og eventuelt deres farmasøytisk akseptable syreaddisjonssalter.
Eksempler på alkylgrupper med 1-4 carbonatomer er methyl,
ethyl, propyl, isopropyl, butyl, sek.-butyl og t-butyl.
Oppfinnelsen innbefatter også fremstilling av de farmasøy-tisk akseptable ikke-toksiske syreaddisjonssalter av basene av formel I med organiske og uorganiske syrer. Eksempler på slike organiske salter er de som dannes med maleinsyre, fumarsyre, vin-syre, ravsyre og lignende. Eksempler på slike uorganiske salter er de som dannes med saltsyre, hydrobromsyre og fosforsyrer.
Analogifremgangsmåten ifølge oppfinnelsen er kjennetegnet ved at
a) for fremstilling av en forbindelse med formel I hvor Am er dialkylamino hvor alkylaruppen har 1-4 carbonatomer, at
2-(2-p-klorfenylethyl)-pyridin med formelen
omsettes med et sekundært amin Am-H hvor Am er dialkylamino hvor alkylgruppen har 1-4 carbonatomer og paraformaldehyd,og b) for fremstilling av forbindelser med formel I hvor Am = NI^/ at a-p -klorbenzyl-2-pyridylaceto-nitril av formelen
reduseres med lithiumaluminiumhydrid, og om ønsket, at de opp-nådde forbindelser overføres i sine syreaddisjonssalter.
Reaksjonene kan illustreres som følger:
hvor Am har de tidligere angitte betydninger.
Generell metode ved fremstilling av 2-(2-pyridyl)-3-(p-klor-fenyl)-propylaminer
(a) En lavere alkanol vann-løsning inneholdende 2-(2-p-klor-
fenylethyl)-pyridin, et sekundært amin og paraformaldehyd kokes under tilbakeløp i fra 40 til 100 timer inntil aliquot-analyser
av reaksjonsblandingen ved hjelp av f.eks. gasskromatografi, in-dikerer at en betydelig mengde av sluttproduktet er dannet. Produktet isoleres fra reaksjonsblandingen ved hjelp av en egnet metode slik som f.eks. syre-base-ekstraksjon, restoljen kromatogra-feres på en magnesiumsilikatkolonne eller basen omdannes til et syreaddisjonssalt som renses ytterligere ved omkrystallisasjon fra et egnet løsningsmiddel.
(b) En omrørt, tørr etherblanding av lithiumaluminiumhydrid
og aluminiumklorid behandles med tørr etherløsning av et
ct-p-klor-benzyl-2-pyridylacetonitril. Etter omrø-ring i fra 1 til 5 timer spaltes reaksjonsblandingen forsiktig ved tilsetning av vann, lagene fraskilles og produktet isoleres fra det organiske lag ved syre-base-ekstraksjon. Produktet omdannes til et egnet syreaddisjonssalt som renses ytterligere ved omkrystallisasjon fra et egnet løsningsmiddel.
Forbindelsene fremstilt ifølge oppfinnelsen er nyttige på grunn av deres farmakologiske virkning med hensyn til å undertrykke volumet av mage-tarmseksjonene ved forsøk med underbinding av polyrus (Shay-rotte). Aktiviteten er merkbar når forbindelsene anvendes i form av deres frie baser eller i form av deres ikke-toksiske syreaddisjonssalter. Den foretrukne form er som ikke-toksiske syreaddisjonssalter på grunn av øket vannløse-lighet og lett administrerbarhet.
Den farmakologiske virkning med hensyn til å undertrykke mage-tarmsekresjonen ved forsøk med underbinding av pylorus (Shay-rottetesten) ble undersøkt for forbindelsene fremstillet ifølge eksempler 2 og 3.
Resultatene var:
Forbindelsen ifølge eksempel 1 var inaktiv i en dose på
50 mg/kg.
Anvendbare preparater inneholdende minst en av forbindelsene som fremstilles ifølge oppfinnelsen sammen med en farmasøy-tisk bærer eller eksipient kan fremstilles etter kjente metoder. Preparater for oral administrering kan være faste eller flytende
og kan foreligge i form av kapsler, tabletter og overtrukne tabletter, hvilke komposisjoner inneholder de bærere eller eksipi-enter som vanligvis anvendes innen faget. Egnede tabletterings-eksipienter innbefatter lactose, potet- og maisstivelse, talkum, gelatin og stearin- og siliciumsyrer, magnesiumstearat og poly-vinylpyrrolidon.
Preparatene kan formuleres som enhetsdoser, idet hver enhet er beregnet til å tilføre en bestemt dose aktiv bestanddel. Tabletter, kapsler og overtrukne tabletter er eksempler på foretrukne enhetsdoser. Enhetsdosene kan inneholde 5 mg eller mer, og fortrinnsvis 25, 50 og 100 mg.
Preparatene kan administreres til pattedyr for å undertrykke den sekretoriske aktivitet, og den administrerte dose vil avhenge av sykdomsgrad og kroppsvekten til det pattedyr som behandles .
De utgangsmaterialer som anvendes ved fremstilling av de nye forbindelser, er forbindelser av formel II og Hl. De er begge kommer-sielt tilgjengelige eller kan fremstilles ved de fremgangsmåter som er beskrevet i det etterfølgende.

Etter 1 time viste aliquot-analyse 50 % omdannelse. Ytterligere 40 ml (0,064 mol) butyllithium i hexan ble tilsatt, og etter 1 times reaksjon ble 24,2 g (0,15 mol) p-klorbenzylklorid tilsatt ved -45°C. Reaksjonsblandingen ble holdt under -35°C i 3 timér og fikk deretter stige til romtemperatur. Etter omrøring over natten ble reaksjonsblandingen helt over i vann, det organiske sjikt ble fraskilt, vasket med vann, tørket (magnesiumsulfat) og fordampet ved redusert trykk under dannelse av 39,3 g residuum. Destilla-sjon av residuet ved 0,10 mm ga 3 fraksjoner som destillerte over ved 115 - 120°C, 120-125°C og 130-135°C. Mengden av de 3 fraksjoner var 26,3 g (81,1 %).

Reaksjonsblandingen ble nøytralisert med 5N natrium-hydroxydløsning, og de organiske bestanddeler ble ekstrahert i kloroform. Kloroformekstraktene ble vasket med vann, tørket (magnesiumsulfat) og konsentrert under redusert trykk til en olje som veide 14,6 g. Oljen ble kromatografert på en kolonne av mag-nesiumsilikat under anvendelse av benzenaceton som elueringsmiddel. 3-fenyl-2-(2-pyridyl)-N,N-dimethylpropylamin-produktet eluert fra kolonnen veide 8,3 g. Basen ble løst i varm isopropanol og omdannet til fumaratsaltet som smeltet ved 100 - 102°C. Kjernemagnetisk resonansanalyse av saltet viste 1,5 fumaratmolekyler for hvert molekyl av basen.
