Description

Foreliggende oppfinnelse angår 3-nitrokinoliner som
er anvendbare for fremstilling av visse lH-imidazo[4,5-c]-kinolinforbindelser som er anvendbare som bronchodilatorer og/eller som antivirale midler.
Oppfinnelsen angår hittil ukjente forbindelser av formel XX, som er kjennetegnet ved at de har formelen
hvori hver gruppe R5 uavhengig er valgt fra alkyl med 1 til 4 carbonatomer, alkoxy med 1 til 4 carbonatomer og halogen, og n er et helt tall 0-2, forutsatt at hvis n er 2, inneholder R5-substituentene til sammen ikke mer enn 6 carbonatomer; R6 er valgt fra hydroxyalkyl med 1 til 6 carbonatomer, dihydroxy-
alkyl med 1 til 6 carbonatomer og cyclohexylmethyl; og R7 er valgt fra alkyl med 1 til 4 carbonatomer og hydrogen.
Forbindelsene er anvendbare som mellomprodukter ved fremstilling av terapeutisk aktive lH-imidazo[4,5-c]kinolin-forbindelser som beskrevet i norsk patentsøknad 844565 (utleg-ningsskrift 163.819).
Forbindelsene kan fremstilles som vist i etter-
følgende reaksjonsskjerna:
I trinnet omsettes et eventuelt substituert 3-nitro-4-klorkinolin av formel IV, hvori R7 er som ovenfor definert,
ved oppvarming med et amin av formel NH-R6 i et egnet løsnings-middel, slik som vann eller tetrahydrofuran, under dannelse av et kinolin av formel V.
Oppfinnelsen illustreres nærmere i de etterfølgende eksempler.
Eksempel 1
Fremstilling av en forbindelse av formel V
Til en løsning av 50,0 g (0,24 mol) 4-klor-3-nitrokinolin i 300 ml tetrahydrofuran ble tilsatt i små por-sjoner 52,7 g (0,72 mol) isobutylamin. Blandingen ble oppvarmet til tilbakeløpstemperaturen i 1 time og ble deretter inndampet i vakuum. Vann ble tilsatt til residuet, og det faste stoff ble fraskilt ved filtrering. Det faste stoff ble suspendert i 1 liter vann og oppløst ved gradvis tilsetning av konsentrert saltsyre (til pH 3 - 4) etterfulgt av filtrering av oppløsningen. Filtratet ble gjort basisk
(til pH 9 - 10) ved tilsetning av konsentrert ammoniumhydroxyd under dannelse av lysegult 4-(isobutylamino)-3-nitro-kinolin, sra.p. 119 - 121° C' J Den strukturelle bekreftelse ble understøttet av infrarød spektralanalyse.
Under anvendelse av de metoder som er beskrevet i eksempel 1 ut fra de angitte substituerte kinoliner og primære aminer ble følgende forbindelser av formel V frem-stilt (tabell I) .
Eksempel 6
Fremstilling av en forbindelse av formel VI
Til en oppløsning av 57,3 g (0,23 mol) 4-(isobutyl-amino)-3-nitrokinolin (fra eksempel 1) i 600 ml ethanol ble tilsatt 2 g platina-på-carbon, og den resulterende blanding ble hydrogenert i en Parr-apparatur i 3 timer. Filtrering etterfulgt av inndampning i vakuum ga et residuum som gradvis størket til et gult fast stoff, 3-amino-4-(isobutyl-amino) -kinolin.
Under anvendelse av metoden beskrevet i eksempel
6 ut fra de angitte mellomprodukter av formel V ble frem-stilt de mellomprodukter av formel VI som er angitt i tabell II. I de tilfeller hvor hydrokloridet er angitt, ble dette oppnådd ved først å boblehydrogenklorid gjennom en ethan-oppløsning av det frie amin hvorpå det faste produkt ble fraskilt ved filtrering.
Eksempel 11
0,207 mol urent 3-amino-4-(methylamino)kinolin erholdt ved fremgangsmåten ifølge eksempel 6 ble blandet med 500 ml iseddik og 76 ml triethylorthoacetat, og den resulterende blanding ble oppvarmet under tilbakeløpskjøling i 2 timer. Inndampning ga et residuum som ble oppløst i 800 ml vann. Oppløsningen ble gjort basisk med konsentrert ammoniumhydroxyd. Det faste stoff ble fraskilt ved filtrering og vasket med vann under dannelse av 1,2-dimethyl-lH-
imidazo [4 ,5-c]kinolin. Når en prøve av dette produkt ble omkrystallisert med diethylether hadde den et smeltepunkt på 194 - 196° c.
Eksempel 16
Del A
En blanding av 26,1 g (0,125 mol) 4-klor-3-nitrokinolin, 16,4 g (0,12 75 mol) 95 % cyclohexylmethylamin og 16,5 g (0,125 mol) 95 % diisopropylethylamin i 300 ml tetrahydrofuran ble oppvarmet på et dampbad i 1/2 time. Oppløs-ningen ble inndampet og resten ble oppslemmet i methanol,
ble filtrert og vasket med methanol. Omkrystallisering fra methanol ga gule plaster av 4-cyclohexylmethylamino-3-nitro-kinolin, sm.p. 140 - 142° C.
Analyse for C^gH^<gN>3°<2:>
Beregnet: C 67,3 H 6,7 N 14,7 %
Funnet : C 67,3 H 6,6 N 14,7 %
Del B
Under anvendelse av metoden ifølge eksempel 26 ble 17 g (0,60 mol) 4-cyclohexylmethylamino-3-nitrokinolin redu-sert til 3-amino-4-cyclohexylmethylaminokinolin.
Del C
Det urene produkt fra del B ble oppvarmet under tilbakeløpskjøling i 2 1/2 time i 250 ml 98 % maursyre under dannelse av 1-cyclohexylmethyl-lH-imidazo[4,5-c]kinolin som et blekgult fast stoff.
