Description
Fremgangsmåte til fremstilling av basisk substituerte heterocykliske forbindelser. Process for the preparation of basic substituted heterocyclic compounds.
Gjenstanden for foreliggende oppfin-nelse er fremstilling av 10-(laveredialkyl-amino-laverealkyl)-ll-okso-dibenzoe-[b,f ] -tia- [1] -aza- [4] -cykloheptadien-[2,6]-forbindelser med en kjerne med formelen The object of the present invention is the production of 10-(lower redialkyl-amino-lower alkyl)-11-oxo-dibenzo-[b,f]-thia-[1]-aza-[4]-cycloheptadiene-[2,6] -compounds with a nucleus with the formula
som bare er substituert i stillingene 6—9 which is only substituted in positions 6—9
og da med minst en metyl- eller metoksygruppe, samt deres salter. and then with at least one methyl or methoxy group, as well as their salts.
Den tertiære aminoalkylrest, hvis al-kylenkjede kan være uf or gr enet eller for-grenet, er særlig en dimetylamino- eller The tertiary aminoalkyl residue, whose alkylene chain can be unbranched or branched, is in particular a dimethylamino or
dietylamino-etyl, -propyl, -i-propyl, -butyl diethylamino-ethyl, -propyl, -i-propyl, -butyl
eller -i-butyl. or -i-butyl.
Disse nye basisk substituerte heterocykliske forbindelser har en antihistamin-virkning og videre en utpreget antiseroto-ninvirkning. De skal anvendes som lege-midler, særlig som middel mot astma. These new base-substituted heterocyclic compounds have an antihistamine effect and furthermore a pronounced antiserotonin effect. They are to be used as medicines, especially as a remedy for asthma.
De nye forbindelser fåes når man i The new connections are obtained when one in
11-okso-dibenzoe- [b;f ] -tia- [ 1] -aza- [4] - 11-oxo-dibenzo-[b;f]-thia-[1]-aza-[4]-
cykloheptadien-[2,6]-forbindelser som er cycloheptadiene-[2,6] compounds which are
usubstituert i 10-stilling, og som bare er unsubstituted in the 10-position, and which only is

Innføringen av denne rest kan f. eks. foretas således at man omsetter de i 10-stilling usubstituerte forbindelser, f. eks. i form av deres metallsalter eller i nærvær av kondensasjonsmidler, særlig slike som formår å danne metallsalter med disse, slik som alkali- og jordalkalimetal-ler, f. eks. natrium, litium, kalsium, deres amider, hydrider kullvannstofforbindelser eller alkoholater, f. eks. natriumamid, na-triumhydrid, butyllitium, fenylkalium, fe-nyllitium, kalium-tert.-butylat eller kali-um-tert.-amylat, med reaksjonsdyktige estere av laveredialkylamino-laverealkoho-ler. Reaksjonsdyktige estere er særlig slike av sterke anorganiske eller organiske syrer, slik som av halogenvannstoffsyrer eller organiske sulfonsyrer, f. eks. p-tolu-olsulfonsyrer. The introduction of this remainder can e.g. is carried out in such a way that the compounds unsubstituted in the 10-position are reacted, e.g. in the form of their metal salts or in the presence of condensing agents, especially those which manage to form metal salts with them, such as alkali and alkaline earth metals, e.g. sodium, lithium, calcium, their amides, hydrides, hydrocarbon compounds or alcoholates, e.g. sodium amide, sodium hydride, butyllithium, phenylpotassium, phenyllithium, potassium tert.-butylate or potassium tert.-amylate, with reactive esters of lower dialkylamino-lower alcohols. Reactive esters are especially those of strong inorganic or organic acids, such as of hydrohalic acids or organic sulphonic acids, e.g. p-toluenesulfonic acids.
Innføringen av den basiske rest kan også foretas trinnvis, f. eks. således at man foretar den ovenfor nevnte omsetning med en reaksjonsdyktig ester av en lavere-al-kanol som har en substituent som kan overføres til en aminogruppe og deretter overfører substituenten til en lavere-di-alkylaminogruppe. Således kan man f. eks. omsette med en sulfonsyreester av en ha-logenlaverealkanol og deretter overføre halogenatomet på vanlig måte ved be-handling med laveredialkylaminer til en tertiær aminogruppe. The introduction of the basic residue can also be carried out in stages, e.g. so that one carries out the above-mentioned reaction with a reactive ester of a lower-alkanol which has a substituent that can be transferred to an amino group and then transfers the substituent to a lower-di-alkylamino group. Thus, one can e.g. react with a sulphonic acid ester of a halogen-lower alkanol and then transfer the halogen atom in the usual way by treatment with lower dialkylamines to a tertiary amino group.
Alt etter arbeidsmåten får man de nye forbindelser i form av deres baser eller salter. Av saltene kan de frie aminbaser utvinnes på i og for seg kjent måte. Av de siste igjen kan det fremstilles salter ved omsetning med syrer, som er egnet for dannelse av terapeutisk anvendelige salter, slik som f. eks. av halogenvannstoffsyrer, svovelsyre, salpetersyre, fosforsyre, rhodanvannstoffsyre, eddiksyre, propion-syre, oksalsyre, malonsyre, ravsyre, eple-syre, metansulfonsyre, etansulfonsyre, ok-syetansulfonsyre, benzol- eller toluolsul-fonsyre eller av terapeutisk virksomme syrer. Depending on the working method, the new compounds are obtained in the form of their bases or salts. The free amine bases can be recovered from the salts in a manner known per se. Of the latter again, salts can be produced by reaction with acids, which are suitable for the formation of therapeutically applicable salts, such as e.g. of hydrohalic acids, sulfuric acid, nitric acid, phosphoric acid, rhodanic hydrogen acid, acetic acid, propionic acid, oxalic acid, malonic acid, succinic acid, malic acid, methanesulfonic acid, ethanesulfonic acid, oxyethanesulfonic acid, benzene or toluenesulfonic acid or of therapeutically active acids.

They are obtained by intramolecular condensation of N-unsubstituted 2-amino-diphenylsulfide-12'-carboxylic acids, which in the benzene nucleus carrying the amino group contain at least one methyl or methoxy group, or their functional derivatives.

Ved omsetning av l-metoksy-3-nitro-4-klor-benzol med tiosalicylsyremetylester i metanol i nærvær av natriummetylat får man 2-nitro-4-metoksy-difenylsulfid-2'-karbonsyremetylester med smeltepunkt 105—106° C. Av dette fremstilles ved katalytisk hydrering 2-amino-4-metoksy-dife-nylsulfid-2'-karbonsyremetylester med smeltepunkt 134—135° C, hvilken, opphetet til 240—270° C, gir 8-metoksy-ll-okso-dibenzoe- [b,f ] -tia- [ 1 ] -aza- [4] -cykloheptadien-[2,6] med sm.p. 218—219° C. By reacting 1-methoxy-3-nitro-4-chloro-benzene with thiosalicylic acid methyl ester in methanol in the presence of sodium methylate, 2-nitro-4-methoxy-diphenylsulfide-2'-carboxylic acid methyl ester is obtained with a melting point of 105-106° C. From this is produced by catalytic hydrogenation 2-amino-4-methoxy-diphenyl sulphide-2'-carboxylic acid methyl ester with melting point 134-135° C, which, heated to 240-270° C, gives 8-methoxy-1-oxo-dibenzo- [ b,f ] -thia- [ 1 ] -aza- [4] -cycloheptadiene-[2,6] with m.p. 218-219° C.
