Description
Kinazolin-derivater anvendelige som mellomprodukter for fremstilling av benzodiazepin-derivater.
Nærværende oppfinnelse vedrorer kinazolin-derivater som er anvendelige som mellomprodukter for, fremstilling av benzodiaze-pinderivater og med den generelle formel
hvor R. er hydrogen, halogen eller nitro, | R2 hydrogen, R^ hydrogen, lavere alkyl eller halo-lavere alkyl, R^ hydrogen eller en alkylgruppe med 1-6 karbon-atomer. Disse forbindelser kan fremstilles ved en fremgangsmåte som består i å la en kinazolinforbindelse med den generelle formel
hvor R^, R£, R^ og R^ har foran angitte betydning og
X er halogen, i ! reagere under vannfrie betingelser med opptil ett mol av en sterk base pr. mol av kinazolinforbindelsen og, hvis onsket, omdannese av et oppnådd produkt til et syreaddisjonssalt.
i 1
Som anvendt her, omfatter lavere alkyl både rettkjedete og forgrenete, mettede hydrokarbongrupper med fra 1-6 karbon-atomer, som f.eks. metyl, etyl, isopropyl og lignende. Uttryk-kene halo, halogen, halogenid etc. omfatter alle fire halogener, dvs. brom, klor, fluor og jod. Uttrykket halo-lavere alkyl omfatter lavere alkylgrupper hvor ett eller flere av hydrogenatomene er erstattet med halogenatomer. Hvor mere enn et halogenatom er tilstede, kan det være like eller forskjel-lige halogener. Når andelen R1 eller omfatter halogen eller en halogen-inneholdende gruppe, er brom eller klor foretrukket. Det samme gjelder for symbolet X. Når andelen R2 omfatter et halogenatom, er klor eller fluor foretrukket. Når andelen R^ omfatter et halo-lavere alkyl, er a-mono-halo lavere alkyler og a,a-dihalo-lavere alkylener, som klormetyl, diklormetyl og lignende foretrukket.
Omdannelsen av et kinazolin-derivat med foran angitte formel
II til en tricyklisk forbindelse med formel I, utfores ved behandling med opptil et mol av en sterk base. Dersom det an-vendes vesentlig mere enn et mol av en sterk base, foregår reaksjonen i annen retning. Forbindelser med formel II, hvor R^ er alkyl og R^ er hydrogen ved behandling med vesentlig mere enn et mol av en sterk base, fortrinnsvis mere enn 2 mol gir 3-alkylen-benzodiazepin 4-oksyder.
Den anvendte sterke base kan f.eks. være et alkalimetall-tertiært-alkoholat, f.eks. natrium- eller kalium-t-butoksyd eller natrium- eller kalium-t-amylat, etc.; et alkalimetall-hydrid, f.eks. natriumhydrid, etc.5 et alkalimetalltrifenyl-metid, f.eks. natriumtrifenylmetid, etc.5 et alkalimetall-sekundært-amid, f.eks. natriumdietylamid, etc. Reaksjonen utfores under vannfrie betingelser. Reaksjonen kan utfores ved romtemperatur eller over eller under romtemperatur, men utfores fortrinnsvis ved ca. romtemperatur. Reaksjonen kan utfores hensiktsmessig i et inert organisk opplosningsmiddel som tetrahydrofuran, benzen, dioksan, dietyleter eller lignende.
Forbindelser med formel I danner syreaddisjonssalter med enten organiske eller uorganiske syrer som eddiksyre, ravsyre, male-insyre, hydrogenhalogensyrer, f.eks. klorhydrogensyre; og bromhydrogensyre, svovelsyre, fosforsyre og lignende.
Forbindelser med formel I er vanlige som kjemiske mellomledd. De er f.eks. anvendelige i fremstillingen av farmasøytisk ver-difulle forbindelser med formlene
i hvor , R3 og R^ har foran angitte betydning. 1 Kinazolin-derivatet med formel II kan fremstilles ved å la 1 enten et a-oksim eller et (3-oksim med formel (hvor R, og R. har foran angitte betydning, reagere med et aldehyd eller keton med den generelle formel !
hvor R^, R. cg X har foran angitte betydning.
Denne reaksjon kan utfores ved å anvende aldehydet eller keto-net med formel V som reaksjonsmedium. Imidlertid kan den også utfores i et inert organisk opplosningsmiddel, fortrinnsvis et i hvilket oksimet er vesentlig opploselig, f.eks. en lavere alkanol, som metanol, etanol eller lignende, eter, dioksan, tetrahydrofuran, lu,uj-dimetoksy-dietyleter, et hydrokarbon, som benzen, toluen eller lignende. Reaksjonen kan utfores ved romtemperatur, forhoyede temperaturer eller under romtemperatur. Ved reaksjon av et a-oksim med formel IV, tilsettes passende
et tungmetallsalt reaksjonsmediet. Den anioniske del av tung-metallsaltet er ikke kritisk og kan oppnås enten fra en organisk eller uorganisk syre, fortrinnsvis det sistnevnte. Det er blitt funnet spesielt hensiktsmessig å anvende et kobbersalt f.eks. kobbersulfat, dvs. å utfore reaksjonen i nærvær av et kobber salt, f.eks. kobbersulfat. Mengden av det anvendte kobbersulfat viser seg ikke å være kritisk, men det er blitt funnet at kobbersalter som kobbersulfat utover en gunstig på-virkning på reaksjonen av a-oksimet med formel IV med et aldehyd eller keton med formel V. Reaksjonen av en forbindelse med formel V med et (3-oksim med formel IV utfores passende i nærvær av et tungmetallsalt, som beskrevet ovenfor for a-oksim, eller i nærvær av en basisk eller sur katalysator. Mengden av den tilstedeværende katalysator er ikke kritisk. Dessuten kan katalysatoren være enten uorganisk eller organisk, f.eks. er en egnet basisk katalysator pyridin eller lignende og egnede sure katalysatorer er hydrogenhalogensyre, som klorhydrogensyre, bromhydrogensyre, eddiksyre eller lignende.
Folgende eksempler illustrerer mere utforlig oppfinnelsen. Alle temperaturer er angitt i Celsiusgrader og alle smeltepunk-ter er korrigerte.
EKSEMPEL 1
En opplosning av 3,55 g (10 mmol) 6-klor-2,2-bis-(klormetyl)-1.2- dihydro-4-fenylkinazolin 3-oksyd i 100 ml tetrahydr<i>ofuran rores om natten over ved romtemperatur med 0,53 g (11 mmol) av en 50 %'ig dispersjon av natriumhydrid i mineralolje. Reaksjonsblandingen filtreres gjennom Celite, fortynnes med vann og ekstraheres med metylenklorid i tre porsjoner. Metylen-kloridekstraktene forenes, vaskes tre ganger med vann og med saltvann og torkes over natriumsulfat. Oppløsningen konsentreres i vakuum, og resten krystalliseres fra benzen-heksan for å gi 7-klor-3-klormetyl-l,3-dihydro-5-fenyl-2H-azirino-(1,2-a)kinazolin 4-oksyd som et lysegult fast stoff, smeltepunkt 133 - 137°. Den analytiske proven oppnås som hvite prismer med smeltepunkt 136 - il38,5° etter tre omkrystallisasjoner fra benzen/heksan. <1>
Utgangsmaterialet kan oppnås på folgende måte:

Reaksjonsblandingen avkjoles til romtemperatur, og produktet filtreres av. Det resuspenderes i vann (75 ml), filtreres og vaskes med vann for å fjerne kobbersulfat, gir 6-klor-l,2-dihydro-2,2-dimetyl-4-fenylkinazolin 3-oksyd som gule prismer, smeltepunkt 200 - 220°.

Etter 1 time oppsamles 1,2 liter opplosningsmiddel. Reaksjonsblandingen avkjoles så på isiog nøytraliseres med 2-n ammoniumhydroksyd (20 ml). Det rester-ende faste produkt oppsamles og vaskes med 1:1 eter/etanol (200 ml) for å gi 6-klor-2,2-bis(klormetyl)-1,2-dihydro-4-fenylkinazolin 3-oksyd, smeltepunkt 169 - 171 o . ;<1>

Til den avkjolte opplosning tilsettes 14,4 g (0,13 mol) kalium-t-butoksyd, og blandingen fjernes fra avkjolingsbadet. Blandingen rores om natten over ved romtemperatur, filtreres gjennom Celite og konsentreres i vakuum. Resten krystalliseres fra benzen og grå-hvitt fast stoff vaskes med eter for å gi 7-klor-3-klormetyl-l,3-dihydro-5- fenyl-2H-azirino(1,2-a)kinazolin 4-oksyd, smeltepunkt 130 - 131°.
EKSEMPEL 3

Spor av natriumhydrid, som ble til-bake, odelegges ved tilsetning av etanol. Blandingen filtreres så, konsentreres til torrhet, og resten krystalliseres fra benzen/heksan for å gi lysegule krystaller av 7-klor-l,3-dihydro-5-fenyl-2H-azirino(1,2-a)kinazolin 4-oksyd, smeltepunkt 125 - 131°.
