Description
Fremgangsmåte til fremstilling av 1-azafentiaziner.
Denne oppfinnelse angår fremgangsmåte til fremstilling av 1-azafentiaziner (og salter derav) samt fremstilling av mel-lomprodukter som kan anvendes i den nevnte fremgangsmåte.
Den i det følgende anvendte nomen-klatur stemmer overens med Patterson og Capells Ring-Index og den som benyttes i Chemical Abstracts.
De stoffer som det dreier seg om (og disses salter) 'har den alminnelige formel
hvor R og R' er like eller forskjellige og re- |
presenterer vannstoff, halogen, hydroksy, lavere alkyl, lavere alkoksy og trihalogen-(lavere alkyl); hvor n er et positivt, helt tall mindre enn 4. De her anvendte uttrykk «lavere alkyl», «lavere alkoksy» skal inn-befatte både rette og forgrenede kjedera-dikaler.
De salter av 1-azafentiaziner som kan fremstilles i henhold til oppfinnelsen inn-befatter syreaddisjonssalter, spesielt sådan-ne som er ikke toksiske. Blant syrer som kan anvendes til fremstilling av syreaddi-sjonssaltene kan nevnes anorganiske syrer som halogenvannstoffsyrer (f. eks. klor-vannstoff- eller bromvannstoffsyre), svo-velsyre, salpetersyre, fosforsyre, borsyre, og organiske syrer som oksalsyre, vinsyre, si-tronsyre, eddiksyre og ravsyre.
Fremgangsmåten for fremstilling av 1-azafentiaziner i henhold til oppfinnelsen kan illustreres ved følgende likninger.
I henhold til det første trinn av fremgangsmåten blir en 2-aminobensoltiol (forbindelsen I) kondensert med et 2-halogen-3-nitropyridin (forbindelsen II) så det dannes et 2-(2'-aminofenyltio)-3-nitropyridin (forbindelsen III). Dette arbeidstrinn skjer fortrinnsvis ved at man blander 2-aminobensoltiol og 2-halogen-3-nitropyridin i om-trent støkiometriske mengder og i nærvær av en base, f. eks. et alkalihydroksyd (ek-sempelvis KOH), et alkalikarbonat eller et alkallalkoholat (f. eks. natriumalkoksyd). Reaksjonen kan foregå ved en hvilken som helst temperatur fra romtemperatur til ko-ning med tilbakeløpskjøling. Det derved dannede 2-(2'-aminofenyltiol)-3-nitropyridin kan utvinnes ved f. eks. filtrering.
Blant 2-aminobensoltioler som kan anvendes i dette trinn av prosessen er: 2-aminobensoltiol, 2-amino-X-halogen-ben-soltiazoler (spesielt slike hvor halogenet er klor eller brom) f. eks. 2-amino-4-klorben-soltiol, 2-amino-4-brombensoltiol, 2-amino-3- klorbensoltiol, 2-amino-5-klor-bensoltiol og 2-amino-6-klorbensoltiol; 2-amino-X,X'-diiialogenbensoltioler; 2-amino-X-hydrok-sybensoltioler; 2-amino-X-(lavere alkyl) - bensoltioler (spesielt de hvor det lavere alkyl er metyl eller etyl), f. eks. 2-amino-4- metyl-bensoltiol, 2-amino-4-etylbensol-tiol, 2-amino-3Hmetylbensoltiol, 2-amino-5- metylbensoltiol og 2-amino-6-metylben-soltiol; 2-amino-X,X'-di(lavere al'kyl)ben-soltioler; 2-amino-X,X',X"-tri (lavere alkyl) bensoltioler; 2-amino-X-halogen-X'-lavere alkyl) bensoltioler; 2-amino-X- (lavere alkoksy)bensoltioler (særlig slike hvor det lavere alkoksy er metoksy)-2-ami-no-X,X'-di(lavere alkoksy)bensoltioler, og 2-amino-X-(lavere alkyl)-X'-(lavere alkyl)bensoltioler. [X,X' og X" representerer naturligvis andre stillinger i bensolkjernen enn 1- og 2-stillingene].
De 2-halogen-3-nitropyridiner som anvendes i det første trinn av fremgangsmåten i henhold til oppfinnelsen er fortrinnsvis 2-jod-, 2-brom- og spesielt 2-klor-3-nitropyridiner. Som eksempler på slike kan nevnes: 2-klor-3-nitropyridin, 2-klor-X-halogen-3-nitropyridiner (særlig slike hvor halogenet er klor) f. eks. 2,5-diklor-3-nitropyridin og 2,6-diklor-3-nitropyridin, 2-klor-X-hydroksy-3-nitropyridiner, 2-klor-X- (lavere alkyl)-3-nitropyridiner (særlig de hvor det lavere alkyl er metyl eller etyl) f. eks. 2-klor-3-nitro-4-pikolin, 6-klor-5-nitro-2-pikolin, 6-klor-5-nitro-3-pikolin, 2-klor-3-nitro-4-etylpyridin , 2-klor-3-nitro-5-etyl-pyridin, og 2-klor-3-nitro-6-etylpyridin; 2-klor-X,X'-di(lavere alkyl)-3-nitropyridiner
(særlig slike hvor det lavere alkyl er metyl eller etyl) for eksempel 6-klor-5-nitro-2,4-lutidin og 6-klor-5-nitro-3,4 lutidin; 2-klor-X-halogen-X'-(lavere alkyl)-3-nitro-pyridiner (særlig slike hvor halogenet er klor og det lavere alkyl er metyl eler etyl), 2-klor-X-(lavere alkoksy)-3-nitropyridiner,
2-klor-X-(lavere alkyl)-X'-(lavere alkoksy)-3-nitropyridiner, og 2-klor-X,X',X"-tri-(lavere alkyl)-3-nitropyridiner, [X, X' og X" representerer naturligvis andre stillinger i pyridinkjernen enn 2- og 3-stillingene].
I henhold til det neste trinn i fremgangsmåten i henhold til oppfinnelsen blir det 2-(2'-aminofenyltio)-3-nitropyridin (forbindelsene III) som er dannet i det første arbeidstrinn cyklisert og rearrangert ved behandling med alkali så det dannes et 1-azafentiazin (forbindelsene VI). [1-azafentiazin kan også kalles 10-H-pyrido-[3,2-b] [1,4] bensotiazin, men betegnes i det følgende for enkelhets skyld med det første mere konsise navn].
Denne cyklisering og rearrangering kan utføres i ett, to eller tre trinn, alt etter reaksjonsforholdene. Hvis f. eks. forbindelsen III behandles med to ekvivalenter alkali, f. eks. natrium- eller kaliumhydroksyd, får man direkte en forbindelse VI, men med forholdsvis lite utbytte. Hvis en forbindelse III behandles med et acyleringsmiddel, f. eks. med et syreanhydrid (R"CO)20 eller et acylhalogenid (R"CO-halogen), fortrinnsvis et klorid, hvor R" er et organisk radikal som f. eks. et kullvann-stoffradikal som inneholder mindre enn.10 kullstoffatomer (f. eks. lavere alkyl, aryl eller aralkyl), dannes det tilsvarende N-acylerte derivat (forbindelsen IV). Denne reaksjon utføres mest fordelaktig ved at forbindelsen III behandles med et karbon-syreanhydrid (best et anhydrid av en lavere fettsyre, som f. eks. eddiksyreanhydrid) fortrinnsvis i nærvær av en katalysator som f. eks. en organisk base (f. eks. pyridin eller kollidin) eller et 'karbonylklorid (f. eks. et klorid av en lavere fettsyre, som acetylklorid). De således dannede forbin-delser IV kan så enten direkte omdannes til forbindelsene VI ved behandling med to ekvivalenter alkali eller, fortrinnsvis, omdannes til det tilsvarende 10-acylerte-l-azafentiazin (forbindelsene V) ved å behandles med en ekvivalent alkali. Begge disse reaksjoner blir fortrinnsvis utført i et organisk oppløsningsmiddel for alkaliet (best i en fortynnet oppløsning). Alkoholer og ketoner er egnede oppløsningsmidler. Da cykliseringen og rearrangeringen foregår hurtig og man ønsker å avslutte reaksjonen raslet for derved å minske muligheten for uønskede side-reaksjoner, bør oppløsnings-midlet være flyktig og således lett kunne fjernes fra reaksjonsblandingen ved destil-lering eller fordampning. Blant egnede flyktige oppløsningsmidler kan nevnes de lavere aLkanoler (f. eks. etanol) og di-(lavere alkyl)ketoner (f. eks. aceton). Forbindelsene V blir deretter hydrolysert ved å behandles enten med en syre (f. eks. saltsyre eller en base (f. eks. natriumhydrok-syd) hvorved man får det tilsvarende 1-azafentiazin (forbindelse VI).
De følgende eksempler illustrerer oppfinnelsen. De tre første eksempler angir fremgangsmåter til fremstilling av 2-(2'-aminof enyltio) -3-nitropyridiner: Eksempel 1.
2- ( 2'- aminof enyltio) - 3- nitropyridin.
Til en oppløsning av 250 g (2,0 mol) 2-aminobensoltiol i 1 liter metanol, gjennom hvilken det er blitt diffundert kvelstoff i 15 minutter, settes det dråpevis (1/2 time) og under omrøring en oppløsning av 132 g (2 mol) 35 pst.'s kaliumhydroksyd i 1 liter 95 pst.'s alkohol. Temperaturen, som var blitt holdt på 5—10° C, får nå stige til 15° C, og under kraftig omrøring tilsettes det gradvis (2 timer) en oppløsning av 315 g (2 mol) 2-klor-3-nitropyridin i 3 liter varm alkohol. Etter ytterligere 1 times om-røring blir reaksjonsblandingen avkjølt til 0°, omrøres kortvarig (15 min.) og produktet filtreres fra og vaskes ved å omrøres med 1,5 liter koldt vann; smp. 124—125°. Utbyttet er ca. 477,5 g (96 pst.).
Analyse beregnet for CnHi!)N:iO^S: C = 53,42; H = 3,66; N = 16,99; N. E. = 247,3. Funnet: c = 53,74; H = 3,92; N = 13,63; N. E. = 245.
Eksempel 2.
2- ( 4'- klor- 2'- aminojenyltio) - 3- nitropyridin.
Ved å anvende 2 mol 2-amino-4-klor-bensoltiol [kfr. Lankelma og Kanuf; J. Am. Chem. Soc, 53, 309 (1931)] i stedet for 2-aminobensoltiol i eks. 1, får man 2-(4'-klor-
2'-aminofenyltio)-3-nitropyridin med godt utbytte.
Eksempel 3.
2- ( 2'- aminof enyltio)- 6- klor- 3- nitropyridin.
Til en oppløsning av 25 g 2-aminobensoltiol i 100 ml metanol, gjennom hvilken det er blitt ledet kvelstoff, settes det dråpevis en oppløsning av 13,2 g kaliumhydroksyd i 100 ml 95 pst.'s etanol. Deretter tilsettes 19,3 g 2,6-di-klor-3-nitropyridin. Blandingen opphetes i 1 time med tilbake-løpskjøling, avkjøles og filtreres, hvorved men får 2-(2'-aminofenyltio)-6-klor-3-nitropyridin. Stoffet 2,6-diklor-3-nitropyridin ble fremstilt ved direkte klorering av 3-aminopyridin og etterfølgende oksydering av 2,6-diklor-3-aminopyridinet med 30 pst.'s vannstoffperoksyd. 2,6-diklor-3-nitropyridin 'kan også fremstilles ved å la 2,6-dihydroksy-3-brompyridin reagere med vandig ammoniakk og koppersulfat så man får 3-amino-2,6-dihydroksypyridin som omdannes til 2,6-diklor-3- aminopyridin ved behandling med PClr,-POCl:! og deretter med vannstoffperoksyd til 2,6-diklor-3-nitropyridin.
Ved å anvende forskjellige andre (R')„-substituerte 2-aminobensoltioler i stedet for 2-aminobensoltiol i eks. 1 eller 3, eller 2-amino-4-klorbensoltiol i eks. 2, fremstilles de tilsvarende substituerte 2-(2'-aminofe-nyltio)-3-nitropyridiner. Hvis på liknende måte andre (R)M-substituerte 2-klor-3-ni-tropyridiner anvendes i stedet for 2-klor-3-nitropyridin i eks. 1 eller 2, eller for 2,6-diklor-3-nitropyridin i eks. 3, får man de tilsvarende substituerte 2-(2'-aminofenyl-tio)-3-nitropyridiner. I de tilfeller hvor det ønskede (R)n-substituerte 2-klor-3-nitropyridin ikke er å få i handelen kan det lett fremstilles av således (R)n-substituert 2-aminopyridin ved å nitrere sistnevnte med salpetersyre og omsette det derved dannede
(R)I1-substituerte-2-amino-3-nitropyridin
til det tilsvarende (R)n-substituerte 2-klor-3- nitropyridin ved behandling med salpe-tersyrling og klorvannstoffsyre.

Eksempel 4.
2'- 3- nitro- 2- pyridyltio ) acetanilid.
Til en blanding av 1750 ml eddiksyreanhydrid og 200 ml pyridin settes det gradvis (1/2 time) ved 20—30° C og under kraftig omrøring 483 g (1,95 mol) 2-(2'-aminof enyltio) -3-nitropyridin. Reaksj onsblan-dingen oppvarmes deretter ved 85° C på dampbad i 15 min., og avkjøles så til 0°. Etter 1/2 times omrøring filtreres produktet fra, omrøres med 1,5 1 vann, filtreres og tørkes. Man får ca. 388 g (69 pst.) produkt som har smp. ca: 141—142°. Etter omkrystallisering fra isopropanol smelter produktet ved ca. 138—139° C.

Eksempel 6.
2'-( 6- klor- 3- nitro- 2- pyridyltio) acetanilid.
Ved å anvende 2 mol 2-(2'-aminofenyl-tio) -6-klor-3-nitropyridin i stedet for 2-(2'-aminofenyltio)-3-nitropyridin i eks. 4 får man 2'- (6-klor-3-nitro-2-pyridyltio) acetanilid.
Andre syreanhydrider og/eller acylha-logenider kan anvendes i stedet for eddik-syreanhydridet i eks. 4—6, hvorved man får de tilsvarende N-acylerte derivater. Den akkurate kjemiske natur av acyleringsmid-let er uten betydning da dets funksjon bare er å beskytte aminradikalet i de neste to trinn av den foretrukne fremgangsmåte i henhold til oppfinnelsen, hvoretter det fjernes ved hydrolyse, og ikke opptrer i det terapeutisk virksomme sluttprodukt.
