For fremstilling av aminoalkoholer med den generelle formelFor the preparation of amino alcohols of the general formula

I etter den under punkt a) karakteriserte fremgangsmåte reduseres aminoketoner med den generelle formel II. Reduksjonen av ketogruppen kan f.eks. foretas katalytisk ved hjelp av metaller fra det periodiske systems 8. gruppe, fortrinnsvis med nikkelkatalysatorer, i nærvær av hittil vanlige oppløsningsmidler, f.eks. vandige alkoholer, alkoholer eller vann. Reduksjonen lar seg også gjennomføre med nascerende hydrogen, f.eks. med aluminiumamalgam og alkohol, natriumamalgam, litiumaluminiumhydrid, natriumborhydrid eller også elektrolytisk. In accordance with the method characterized under point a), aminoketones with the general formula II are reduced. The reduction of the keto group can e.g. is carried out catalytically using metals from the 8th group of the periodic table, preferably with nickel catalysts, in the presence of hitherto common solvents, e.g. aqueous alcohols, alcohols or water. The reduction can also be carried out with nascent hydrogen, e.g. with aluminum amalgam and alcohol, sodium amalgam, lithium aluminum hydride, sodium borohydride or also electrolytically.

Fremstillingen av utgangsketonet med den generelle formel II kan eksempelvis foregå ved omsetning av 1,1-difenylpropyl-(3)-&min, hvori en fenylrest eventuelt er substituert med en metoksygruppe eller av l-fenyl-l-pyridyl(2<*>)-propyl(3)-amin med halogenketoner med formel Denne omsetning gjennomføres fordelaktig i nærvær av halogenhydrogen-avspaltende midler. Man kan også fremstille utgangsstoffer med den generelle formel II, idet man omsetter 1,1-difenyl-3-halogenpropaner eller 1-fenyl-l-pyridyl(2<*>)-3-halogen-propaner med de tilsvarende aminoketoner med formel The preparation of the starting ketone with the general formula II can, for example, take place by reaction of 1,1-diphenylpropyl-(3)-&min, in which a phenyl residue is optionally substituted with a methoxy group or of l-phenyl-l-pyridyl(2<*>) -propyl(3)-amine with haloketones of the formula This reaction is carried out advantageously in the presence of halohydrogen-releasing agents. Starting substances with the general formula II can also be prepared by reacting 1,1-diphenyl-3-halopropanes or 1-phenyl-1-pyridyl(2<*>)-3-halopropanes with the corresponding amino ketones of formula

Fremstillingen av fremgangsmåteproduktene av den angitte generelle formel I kan også foregå således at man avalkylerer på vanlig måte ifølge fremgangsmåte b) tilsvarende forbindelser, hvori R^betyr en alkylrest, eller at man i forbindelser hvori R^betyr en benzylgruppe, avspalter denne. Avalkyleringen kan eksempelvis foretas ved oppvarmning av bromhydrogen eller med aluminlumklorid eller med pyridinhydroklorid. Benzylrestens avspaltning foregår fortrinnsvis katalytisk under anvendelse av edelmetallkatalysatorer som f.eks. palladiumsort, kan f.eks. også foretas ved koking med bromhydrogensyre. The preparation of the process products of the specified general formula I can also proceed by dealkylating in the usual way according to process b) corresponding compounds, in which R^ means an alkyl residue, or that in compounds in which R^ means a benzyl group, this is cleaved off. The dealkylation can be carried out, for example, by heating hydrogen bromine or with aluminum chloride or with pyridine hydrochloride. The removal of the benzyl residue preferably takes place catalytically using noble metal catalysts such as e.g. palladium black, can e.g. also carried out by boiling with hydrobromic acid.

Fremstillingen av utgangsstoffer med den generelle formel III for den under punkt b) anførte fremgangsmåte foregår analogt forbindelser med den generelle formel II. 1,1-difenylpropyl-3-amin resp. 1-fenyl-l-pyridyl(2)-propyl(3)-amin kan eksempelvis omsettes med halogenerte etere med formel The production of starting substances with the general formula III for the method listed under point b) takes place analogously to compounds with the general formula II. 1,1-diphenylpropyl-3-amine or 1-phenyl-1-pyridyl(2)-propyl(3)-amine can, for example, be reacted with halogenated ethers of the formula

eller med oksoforbindelser med den generelle formel idet omsetningen må foregå med oksoforbindelsen under samtidig eller etterfølgende reduksjon. Endelig kan utgangsstoffene med den generelle formel III også fremstilles av difenylmetan, 2-benzylpyridin eller difenylacetonitril, resp. deres metoksy-substituerte derivater, ved omsetning med halogenerte etere med den generelle formel or with oxo compounds of the general formula, as the reaction must take place with the oxo compound during simultaneous or subsequent reduction. Finally, the starting materials with the general formula III can also be prepared from diphenylmethane, 2-benzylpyridine or diphenylacetonitrile, resp. their methoxy-substituted derivatives, by reaction with halogenated ethers of the general formula

idet en eventuell tilstedeværende CN-gruppe avspaltes på i og for seg kjent måte. N-benzylgruppen kan avspaltes før eller etter eter-spaltningen, fortrinnsvis ved katalytisk hydrering. Betyr også in that any CN group present is split off in a manner known per se. The N-benzyl group can be removed before or after the ether cleavage, preferably by catalytic hydrogenation. Also means

en benzylgruppe, så kan de to 0- og N-benzylgrupper avspaltes i en arbeidsprosess ved katalytisk hydrering. a benzyl group, then the two 0- and N-benzyl groups can be split off in a working process by catalytic hydrogenation.

De for den under punkt c) oppførte fremgangsmåte nødvendige utgangsstoffer med den generelle formel IV kan fremstilles på tilsvarende måte som beskrevet for forbindelsene II og III. Som utgangsstoffer kommer det eksempelvis forbindelser i betraktning med den generelle formel IV, hvori Ac betyr acetyl, propionyl- eller benzoyl-resten. Hydrolysen foretas på vanlig måte enten i vandig alkalisk medium eller med alkoholisk resp. vandig-alkoholisk lut. Man kan også forsåpe med fortynnede syrer resp. saltsyre eller svovelsyre. The starting materials with the general formula IV required for the method listed under point c) can be prepared in a similar way as described for compounds II and III. As starting materials, for example, compounds with the general formula IV are taken into consideration, in which Ac means the acetyl, propionyl or benzoyl residue. The hydrolysis is carried out in the usual way either in an aqueous alkaline medium or with alcoholic or aqueous-alcoholic lye. You can also saponify with diluted acids or hydrochloric or sulfuric acid.

En ytterligere utførelsesform av fremgangsmåten ifølge punkt d) består i at man i forbindelse med formel V hydrerer C-C-dobbelt-bindingen. Reduksjonen foregår fortrinnsvis katalytisk under anvendelse av metaller fra det periodiske systems 8. gruppe, fortrinnsvis med edelmetaller. Som oppløsningsmidler egner det seg for hydrering vanlige oppløsningsmidler, f.eks. alkoholer, vann eller vandige alkoholer. A further embodiment of the method according to point d) consists in hydrogenating the C-C double bond in connection with formula V. The reduction preferably takes place catalytically using metals from the 8th group of the periodic system, preferably with noble metals. Suitable solvents for hydration are ordinary solvents, e.g. alcohols, water or aqueous alcohols.

Fremstillingen av utgangsstoffet med den generelle formel VThe preparation of the starting material of the general formula V

kan eksempelvis foregå ved kondensasjon av forbindelser med den can, for example, take place by condensation of compounds with it

generelle formel XII med aminer med formel XIII general formula XII with amines of formula XIII

og partiell hydrering ifølge den i Bull Soc. Chim. France 1952. side IO46 beskrevne fremgangsmåte. and partial hydration according to that in Bull Soc. Chim. France 1952. page IO46 described method.

En ytterligere fordelaktig mulighet til fremstilling av de ønskede forbindelser består i at man ifølge punkt e) omsetter aminer med den generelle formel VI med etylenoksyder av den generelle formel VII, idet reaksjonen fortrinnsvis gjennomføres i nærvær av et opp-løsningsmiddel, f.eks. etanol, og ved forhøyet temperatur. A further advantageous possibility for the production of the desired compounds consists in, according to point e), reacting amines of the general formula VI with ethylene oxides of the general formula VII, the reaction preferably being carried out in the presence of a solvent, e.g. ethanol, and at elevated temperature.

Som etylenoksyder kommer det eksempelvis på tale: 1- (3» 4-dimetylfenyl)-etylenoksyd, 1-(3,4-dimetylfenyl)-2-metyl-etylenoksyd, 1-(3,4-dietylfenyl)-etylenoksyd, 1-(314-dietylfenyl)-2- metyl-etylenoksyd. Ethylene oxides include, for example: 1-(3,4-dimethylphenyl)-ethylene oxide, 1-(3,4-dimethylphenyl)-2-methyl-ethylene oxide, 1-(3,4-diethylphenyl)-ethylene oxide, 1- (314-Diethylphenyl)-2-methyl-ethylene oxide.

En ytterligere fremstillingsmulighet ifølge oppfinnelsen gående ut fra aminet med formel VI består i at man underkaster disse reduksjon i nærvær av ketoner eller aldehyder med formel VIII. Som slike ktetoner resp. aldehyder kommer det eksempelvis i betraktning: 1-(3,4-dimetylfenyl)-glykol-l2)-aldehyd, 1-(3»4-dimetylfenyl)-l-hydroksy-2-okso-propan, 1-(3,4-dietylfenyl)-glykol(2)-aldehyd, l-(3,4-dietylfenyl)-l-hydroksy-2-okso-propan. A further production possibility according to the invention starting from the amine of formula VI consists in subjecting these to reduction in the presence of ketones or aldehydes of formula VIII. As such ketones resp. aldehydes, for example: 1-(3,4-dimethylphenyl)-glycol-12)-aldehyde, 1-(3,4-dimethylphenyl)-1-hydroxy-2-oxo-propane, 1-(3,4 -diethylphenyl)-glycol(2)-aldehyde, 1-(3,4-diethylphenyl)-1-hydroxy-2-oxo-propane.

Reduksjonen foregår fortrinnsvis ved katalytisk hydrering av ekvimolare mengder av begge forbindelser i nærvær av et indifferent oppløsningsmiddel. Som katalysator anvender man metaller fra det periodiske systems 8. gruppe, fortrinnsvis edelmetaller. The reduction preferably takes place by catalytic hydrogenation of equimolar amounts of both compounds in the presence of an indifferent solvent. As a catalyst, metals from the 8th group of the periodic system are used, preferably precious metals.

Som oppløsningsmidler egner det seg de for hydrering vanlige oppløsningsmidler, som alkoholer, vandige alkoholer eller vann. Det kan også anvendes nikkelkatalysator. Likeledes kan man også først kondensere oKsoforbindelsene med formel VIII med aminene med formel VI, og deretter redusere kondensasjonsproduktet med nacerende hydrogen, f.eks. med aluminiumamalgam og alkohol, natriumamalgam, litium aluminiumhydrid eller natriumborhydrid. Reduksjonen er også gjennomførbar elektrolytisk. Suitable solvents are the usual solvents for hydration, such as alcohols, aqueous alcohols or water. A nickel catalyst can also be used. Likewise, one can also first condense the oxo compounds of formula VIII with the amines of formula VI, and then reduce the condensation product with nascent hydrogen, e.g. with aluminum amalgam and alcohol, sodium amalgam, lithium aluminum hydride or sodium borohydride. The reduction can also be carried out electrolytically.

Som aminer som kan anvendes som utgangsstoffer for omsetningen ifølge e) kommer det eksempelvis på tale: 3>3-difenylpropylamin, 3- (o|-metoksy-f enyl )-3-f enyl-propylamin,, As amines that can be used as starting materials for the reaction according to e), examples include: 3>3-diphenylpropylamine, 3-(o|-methoxy-phenyl)-3-phenyl-propylamine,,

I 3-(m-metoksy-fenyl)-3-fenyl-propylamin, 3"(p-metoksyfenyl)-3-fenyl-propylamin, In 3-(m-methoxy-phenyl)-3-phenyl-propylamine, 3"(p-methoxyphenyl)-3-phenyl-propylamine,

I 3-fenyl-3-pyridyl(2)-propylamin. In 3-phenyl-3-pyridyl(2)-propylamine.

En ytterligere mulighet til fremstilling av fremgangsmåteproduktene består i kondensasjonen av difenyl-propionaldehyder resp. fenyl-pyridyl(2)-propionaldehyd med formel IX méd aminoalkoholer resp. -ketoner med formel X, etter den under f) karakteriserte fremgangsmåte. Aldehydenes omsetning med aminoalkoholene med samtidig eller etterfølgende reduksjon foregår prinsipielt etter den under e) beskrevne fremgangsmåte for fremstilling av fremgangsmåteproduktene, gående ut fra l-fenyl-3-aminopropanene med formel VI og okso-forbindelser med den generelle formel VIII. A further possibility for the production of the process products consists in the condensation of diphenyl-propionaldehydes resp. phenyl-pyridyl(2)-propionaldehyde of formula IX with amino alcohols resp. -ketones of formula X, according to the method characterized under f). The reaction of the aldehydes with the amino alcohols with simultaneous or subsequent reduction takes place in principle according to the method described under e) for the production of the process products, starting from the l-phenyl-3-aminopropanes of formula VI and oxo compounds of the general formula VIII.

Som utgangsstoffer for omsetninger kommer det i betraktning As starting materials for sales, it comes into consideration

følgende aminer:the following amines:

1—(3•4-dimetylfenyl)l-hydroksy-2-amino-etan, 1-(3»4-dimetylfenyl)-l-hydroksy-2-amino-propan, 1-(3»4-dietylfenyl)-l-hydroksy-2-amino-etan, 1-(3,4-dietylfenyl)-l-hydroksy-2-amino-propan såvel de til de nevnte 1-hydroksyforbindelser tilsvarende l-okso-2-amino-etaner resp. -propanar. 1-(3•4-dimethylphenyl)1-hydroxy-2-aminoethane, 1-(3»4-dimethylphenyl)-1-hydroxy-2-amino-propane, 1-(3»4-diethylphenyl)-1 -hydroxy-2-amino-ethane, 1-(3,4-diethylphenyl)-1-hydroxy-2-amino-propane as well as those of the aforementioned 1-hydroxy compounds corresponding to 1-oxo-2-aminoethanes resp. - propane.

Etter sn ytterligere utførelsosform av fremgangsmåten ifølge pwak% g) tson©an egså redusere karofsnsyrøamldør med form«l 21, idet sws$; aksiell, foffdøifodubsjsuaøn voå hjelp av iifeiiuaaluigiaitjffl&ydrid organiske oppløsningsmidler, som eter, dioksan eller tetrahydrofuran. Hensiktsmessig setter man amidet til litiumaluminiumhydridsuspen-sjonen i en av de nevnte oppløsningsmidler, lar reaksjonsblandingen deretter koke noen tid under tilbakeløp, spalter den deretter forsiktig med vann og opparbeider på vanlig måte ved adskillelse av de organiske fra de uorganiske bestanddeler. Karbonsyreamidenes reduksjon til aminene er videre også gjennomførbar elektrolytisk. Amidene med formel XI kan fremstilles på vanlig måte fra de tilsvarende fenylpropionsyreklorider ved omsetning med aminer av formel X. After sn further embodiment of the method according to pwak% g) tson©an also reduce karofsnsnsyrøamldør with form«l 21, as sws$; axial, foffdøifodubjsuaøn using iifeiiuaaluigiaitjffl&ydrid organic solvents, such as ether, dioxane or tetrahydrofuran. Appropriately, the amide is added to the lithium aluminum hydride suspension in one of the aforementioned solvents, the reaction mixture is then allowed to boil for some time under reflux, it is then carefully split with water and worked up in the usual way by separating the organic from the inorganic components. The reduction of the carboxylic acid amides to the amines can also be carried out electrolytically. The amides of formula XI can be prepared in the usual way from the corresponding phenylpropionic acid chlorides by reaction with amines of formula X.

Fremgangsmåteproduktene kan som basiske forbindelser ved hjelp av uorganiske eller organiske syrer overføres i tilsvarende salter. Som uorganiske syrer kommer det eksempelvis i betraktning: halogen-hydrogensyrer som klorhydrogensyre eller bromhydrogensyre, såvel som svovelsyre, fosforsyre og amidosulfonsyre. Som organiske syrer skal det eksempelvis nevnes: eddiksyre, propionsyre, melkesyre, glukonsyre, glykolsyre, maleinsyre, ravsyre, vinsyre, benzosyre, salicylsyre, sitronsyre, acetursyre, oksyetansulfonsyre og etylendiamintetra-eddiksyre. As basic compounds, the process products can be transferred into corresponding salts by means of inorganic or organic acids. As inorganic acids, for example: halogenated hydrogen acids such as hydrochloric acid or hydrobromic acid, as well as sulfuric acid, phosphoric acid and amidosulphonic acid. As organic acids, examples should be mentioned: acetic acid, propionic acid, lactic acid, gluconic acid, glycolic acid, maleic acid, succinic acid, tartaric acid, benzoic acid, salicylic acid, citric acid, aceturic acid, oxyethanesulphonic acid and ethylenediaminetetraacetic acid.

Fremgangsmåteproduktene er verdifulle legemidler og har en meget god hjerte- og kretsløpsvirkning. Således fører f.eks. en administrering av l-(3',4'-dimetylfenyl)-2-(m-metoksy-difenylpropyl-amino)-propanol(l} i forsøk på isolerte marsvinhjerter ifølge langendorff ved en engangs injeksjon på 5 y til en økning av coronar-gjennomstrømningen av samme størrelsesorden som den også oppnås ved administrering av 5 T*av den kJente forbindelse 1-fenyl-2-/~3<*>,3<*->difenylpropyl-(l')-amino7-propan. The procedure products are valuable medicines and have a very good cardiovascular and circulatory effect. Thus, e.g. an administration of l-(3',4'-dimethylphenyl)-2-(m-methoxy-diphenylpropyl-amino)-propanol(l} in experiments on isolated guinea pig hearts according to langendorff by a single injection of 5 y to an increase of coronary - the throughput of the same order of magnitude as is also achieved by administration of 5 T* of the known compound 1-phenyl-2-/~3<*>,3<*->diphenylpropyl-(1')-amino7-propane.

<F>ordelene ved de nye fremgangsmåteprodukter består imidlertid fremfor alt i at de ved siden av deres coronarkarutvidende virkning har en utpreget B-sympathicolytisk virkning, p-sympathicolytisk virksomme stoffer hemmer virkningen av adrenalin og isopropylnor adrenalin, som består i en økning av hjertefrekvensen og hjertets kontraksjonskraft. Adrenalin og isopropylnoradrenalin øker indirekte over den nevnte virkning, men også direkte hjertestoffsKlftet. En til egnet tidspunkt innsatt aktivering av det sympatiske nervesystem, hvorfor de to stoffer tjener som modeller, kan ved hjertet føre til oksygenmangel, spesielt når coronarkarene har innsnevringer, (ved forkalkning). En p-sympathicolytisk virkning beskytter hortet for slik sterk økning av stoffskiftet. , The advantages of the new method products, however, consist above all in that, in addition to their coronary artery widening effect, they have a pronounced B-sympathicolytic effect, p-sympathicolytically active substances inhibit the effect of adrenaline and isopropyl nor adrenaline, which consists in an increase in the heart rate and heart's force of contraction. Adrenaline and isopropyl norepinephrine indirectly increase the above-mentioned effect, but also directly increase cardiac output. An activation of the sympathetic nervous system initiated at an appropriate time, which is why the two substances serve as models, can lead to a lack of oxygen in the heart, especially when the coronary arteries have narrowings, (in case of calcification). A p-sympathicolytic effect protects the heart from such a strong increase in metabolism. ,

Således viser f.eks. l-(3' ,4'-dimetylf enyl )-2-(3"-m-metoksyfenyl-3"-fenylpropylamino)-propanol(l) på trachealkjeden ifølge Castille med 20 lf på 50 cm^ tyrodeoppløsning en nedsettelse av virkningen av 3 V isopropylnoradrenalin med ca. $ 0%. Sammenlignet hermed er det for å oppnå samme virkning av den kjente forbindelse l-fenyl-2-/<_>3<*>,3'-difenylpropyl-(l')-amino7~propan nødvendig med 500^/50 cm^ tyrodeoppløsning. Fremgangsmåt eprodukt ene har foruten hjerte- og kretsløpsvirkningen dessuten en gunstig blodtrykksenkning. Thus shows e.g. 1-(3',4'-dimethylphenyl)-2-(3"-m-methoxyphenyl-3"-phenylpropylamino)-propanol (1) on the tracheal chain according to Castille with 20 lf of 50 cm^ Tyrode solution a reduction of the effect of 3 V isopropyl norepinephrine with approx. $ 0%. Compared to this, in order to achieve the same effect of the known compound 1-phenyl-2-[_>3<*>,3'-diphenylpropyl-(1')-amino7-propane, 500^/50 cm^ of Tyrode solution is required . Procedure The product has, in addition to its cardiac and circulatory effects, also a beneficial blood pressure reduction.

Således senker f.eks. l-(3',4'-dimetylfenyl)-2-/~fenyl-pyridyl(2" )-propylamino_7-propanol-(l )-hydroklorid på rotter, som har etnyrehøytrykk, blodtrykket sterkt og langvarig. Thus lowers e.g. 1-(3',4'-Dimethylphenyl)-2-/~phenyl-pyridyl(2" )-propylamino_7-propanol-(1 )-hydrochloride on rats, which have renal hypertension, the blood pressure is severe and prolonged.

Det midlere blodtrykk utgjorde ved 11 rotter gjennomsnittlig I92 mm Hg. 2 timer etter den subkutane inngivning av 40 mg Ag av fremgangsmåteproduktet var blodtrykket sunket til 136 mm Hg, og 24 timer etter injeksjonen utgjorde det 168 mm Hg, hadde altså ennå ikke nådd utgangsverdien. The mean blood pressure in 11 rats averaged 192 mm Hg. 2 hours after the subcutaneous administration of 40 mg Ag of the process product, the blood pressure had dropped to 136 mm Hg, and 24 hours after the injection it was 168 mm Hg, thus not yet reaching the initial value.

Det samme fremgangsmåteprodukt viser dessuten en sterkt (3-sympathicolytisk virkning. Det viser f.eks. på trachealkjeden ifølge Castillo med bare 2,5 ^ på 50 cm"^ tyrodeoppløsning en nedsettelse av virkningen av 5|<*>isopropylnoradrenalin med ca. 50%. The same process product also shows a strong (3-sympathicolytic effect. It shows, for example, on the tracheal chain according to Castillo with only 2.5 ^ in 50 cm"^ thyrode solution a reduction of the effect of 5|<*>isopropyl norepinephrine by about 50 %.

På isolerte marsvinhjerter ifølge Langendorff nedsatte det samme fremgangsmåteprodukt ved permanent infusjon av 0,1 pr. minutt den ved 0,1 f isopropylnoradrenalin bevirkede økning av hjertefrekvensen med en tredjedel. På marsvinhjerter ifølge Langendorff ble ved 15 ^ av fremgangsmåteproduktet coronargjennom-strømningen øket tydelig. On isolated guinea pig hearts, according to Langendorff, the same procedure reduced the product by permanent infusion of 0.1 per minute that at 0.1 f isopropyl norepinephrine caused an increase in the heart rate by one third. On guinea pig hearts according to Langendorff, at 15% of the process product, the coronary flow was clearly increased.

Ved kombinasjonen av de tre nevnte virkninger utmerker fremgangsmåt eprodukt ene seg ved spesielle fordeler overfor tidligere kjente forbindelser. Fremgangsmåteproduktene er spesielt gunstige til behandling av hypertoni, •' for nettopp ved hypertonikere er en hjertekranskarutvidende virkning av fordel, da hjertet av høytrfykks-syke har en sterk forhøyet muskelmasse som må ernæres. Dessuten tenderer nyperxoniKeren i-ix ariierisKierose av njerceicransKarene, hvis følger eventuelt kan kompenseres med en utvidelse av de små ikke-forlalkede kar. In the combination of the three aforementioned effects, the eproduct method is distinguished by special advantages over previously known compounds. The process products are particularly beneficial for the treatment of hypertension, because precisely in hypertensive patients a cardiac coronary dilating effect is advantageous, as the heart of a hypertensive patient has a greatly increased muscle mass which must be nourished. Moreover, the neoperxoniKer tends i-ix ariierisKierosis of the njerceicransVessels, the consequences of which can possibly be compensated by an expansion of the small non-perlaced vessels.
