Description
Oppfinnelsen dreier seg om en fremgangsmåte til fremstilling av de nye triazolodiazepinderivater med den generelle formel I The invention relates to a process for the production of the new triazolodiazepine derivatives with the general formula I
hvor where
R-^ betegner hydrogen eller en metylgruppe og^R-^ denotes hydrogen or a methyl group and ^
R2 betegner metyl eller etyl, fortrinnsvis etyl, R 2 denotes methyl or ethyl, preferably ethyl,
og og Rjj er hydrogen eller klor. and and Rjj is hydrogen or chlorine.
Likeledes omfatter oppfinnelsen fremstilling av 5-oksyder av forbindelsene med generell formel I og av addisjonssalter av forbindelser med generell formel I med uorganiske og organiske syrer. Likewise, the invention includes the preparation of 5-oxides of the compounds of general formula I and of addition salts of compounds of general formula I with inorganic and organic acids.
Forbindelsene med generell formel I, deres 5~ok- The compounds of general formula I, their 5~ok-
syder og deres addisjonssalter med uorganiske eller organiske syrer har verdifulle farmakologiske egenskaper. De virker spesi-elt antikonvulsive, sentralnervedempende og muskelavslappende. acids and their addition salts with inorganic or organic acids have valuable pharmacological properties. They are especially anticonvulsant, central nervous system depressant and muscle relaxant.
Den krampehemmende virkning lar seg f.eks. påvise ved pentetrazol-krampetesten på mus med doser fra ca. 0,02 mg/kg per os, samt ved strykninkrampetesten, ved elektrosjokktesten og ved den psyko-motoriske elektrosjokktest på mus etter oral administrasjon. Den sentralnervedempende virkning fremgår f.eks. av den narkosepoten-serende virkning på mus etter oral administrasjon, men fremstår imidlertid mindre sterk sammenlignet med den antikonvulsive eller krampehemmende virkning. Den muskelavslappende virkning fremgår f.eks. av hemmingen av de polysynaptiske reflekser på kaniner etter intravenøs administrasjon. De nevnte og andre virkninger som kommer til uttrykk ved valgte standardforsøk (sammenlign W. Theobald og H.A. Kunz, Arzneimittelforsch. 13, 122 (1963) og The anticonvulsant effect can be e.g. detect in the pentetrazole convulsion test on mice with doses from approx. 0.02 mg/kg per os, as well as in the strychnine seizure test, in the electroshock test and in the psychomotor electroshock test on mice after oral administration. The central nervous system depressant effect can be seen e.g. of the anesthetic potentiating effect on mice after oral administration, but appears less strong compared to the anticonvulsant or anticonvulsant effect. The muscle-relaxing effect can be seen e.g. of the inhibition of the polysynaptic reflexes in rabbits after intravenous administration. The aforementioned and other effects which are expressed in selected standard tests (compare W. Theobald and H.A. Kunz, Arzneimittelforsch. 13, 122 (1963) and
W. Theobald og medarbeidere, Arzneimittelf orsch. 17, 561 (1967).), karakteriserer forbindelsene med generell formel I, deres 5-oksyder og deres farmasøytisk anvendbare addisjonssalter med uorganiske eller organiske syrer, som virkningsfulle stoffer i forbindelse med beroligende midler, sedativa, muskelavslapnings-midler og antiepileptika, f.eks. til behandling av spennings- og opphisselses-tilstander, for nedsettelse av tonus for den tverr-stripede muskulatur og for behandling av epilepsi. W. Theobald et al., Arzneimittelf orsch. 17, 561 (1967).), characterizes the compounds of general formula I, their 5-oxides and their pharmaceutically usable addition salts with inorganic or organic acids, as effective substances in connection with tranquilizers, sedatives, muscle relaxants and antiepileptics, e.g. e.g. for the treatment of states of tension and excitement, for reducing the tone of the striated muscles and for the treatment of epilepsy.

Omsetningen i henhold til oppfinnelsen foretas med fordel ved en reaksjonstemperatur mellom ca. 80 og 160°C i et inert oppløsningsmiddel. Som inert oppløsningsmiddel egner seg f.eks. hydrokarboner som toluen eller xylen, halogenerte hydrokarboner som klorbenzen, lavere alkanoler, fortrinnsvis slike som stemmer overens med acetalgrupperingen, f.eks. etanol eller butanol, eteraktige væsker som dietylenglykoldimetyleter, di-etylenglykoldietyleter eller dioksan og amider, særlig N,N,N', N',N",N"-heksametylfosforsyretriamid, eller sulfoksyder som dimetylsulfoksyd. Reaksjonstidene ligger mellom ca. 1 og 24 timer. The reaction according to the invention is advantageously carried out at a reaction temperature between approx. 80 and 160°C in an inert solvent. As an inert solvent, e.g. hydrocarbons such as toluene or xylene, halogenated hydrocarbons such as chlorobenzene, lower alkanols, preferably those consistent with the acetal grouping, e.g. ethanol or butanol, ethereal liquids such as diethylene glycol dimethyl ether, diethylene glycol diethyl ether or dioxane and amides, especially N,N,N', N',N",N"-hexamethylphosphoric acid triamide, or sulfoxides such as dimethyl sulfoxide. The reaction times are between approx. 1 and 24 hours.
Utgangsstoffene som faller inn under den generelle formel II er beskrevet i litteraturen, se blant annet L.H. Sternbach og E. Reeder, J.Org.Chem. 26, 1111 (1961), S.C. Bell et al., J.Med.Chem. 5, 63 (1962), G.A. Archer og L.H. Sternbach, J.Org. Chem. 29, 231 (1964) og J. Parber og medarbeidere J.Med.Chem. 7, 235 (1964). Videre er det beskrevet forbindelser som faller inn under generell formel III, f.eks. dimetoksyeddiksyrehydrazid (se E.J. Browne og J.B. Polya, J. Chem. Soc. 1962, 5149). Andre forbindelser med generelle formler II og III kan fremstilles analogt med de kjente stoffer. Med fordel fremstilles andre utgangsstoffer med generell formel II, med en eventuelt substituert aminogruppe X, ved reduksjon av de tilsvarende 4-oksyder beskrevet i litteraturen . The starting substances that fall under the general formula II are described in the literature, see among others L.H. Sternbach and E. Reeder, J. Org. Chem. 26, 1111 (1961), S.C. Bell et al., J. Med. Chem. 5, 63 (1962), G.A. Archer and L.H. Sternbach, J. Org. Chem. 29, 231 (1964) and J. Parber et al. J. Med. Chem. 7, 235 (1964). Furthermore, compounds are described which fall under general formula III, e.g. dimethoxyacetic acid hydrazide (see E.J. Browne and J.B. Polya, J. Chem. Soc. 1962, 5149). Other compounds with general formulas II and III can be prepared analogously to the known substances. Advantageously, other starting substances of general formula II, with an optionally substituted amino group X, are prepared by reduction of the corresponding 4-oxides described in the literature.
Som pksydasjonsmiddel for den påfølgende omdannelse av forbinelser med gen-erell formel I til deres 5-oksyder vil fortrinnsvis hydrogeriperoksyd eller persyrer egne seg, ved tempera-turer mellom ca. 0 og 70°C. Egnede persyrer er f.eks. pereddiksyre eller perbenzosyrer som perbenzosyre selv eller særlig in-kl or-perbenzosyre . Oksydasjonsmidlet brukes med fordel i et oppløsningsmiddel som f.eks. pereddiksyre i eddiksyre eller perbenzosyre i halogenerte hydrokarboner som metylenklorid eller kloroform. As an oxidizing agent for the subsequent conversion of compounds with general formula I to their 5-oxides, hydrogen peroxide or peracids will preferably be suitable, at temperatures between approx. 0 and 70°C. Suitable peracids are e.g. peracetic acid or perbenzoic acids such as perbenzoic acid itself or especially in-chlor-perbenzoic acid. The oxidizing agent is advantageously used in a solvent such as e.g. peracetic acid in acetic acid or perbenzoic acid in halogenated hydrocarbons such as methylene chloride or chloroform.

Omsetningen ifølge oppfinnelsen gjennomføres fortrinnsvis i et oppløsningsmiddel, f.eks. i et overskudd av den ;anvendte alkanol med generell formel V eller et alkandiol med generell formel VI, i nærvær av en katalysator. Som katalysator brukes., med fordel en mineralsyre som svovelsyre eller fosforsyre, en aromatisk sulfonsyre som f.eks. o- eller p-toluensulfonsyre, eller en Lewissyre som bortrifluorid. Reaksjonstemperaturen ligger på ca. 20 til 170°C, særlig ved det anvendte oppløsnings-midlets kokepunkt.

A mineral acid such as sulfuric or phosphoric acid, an aromatic sulphonic acid such as e.g. o- or p-toluenesulfonic acid, or a Lewis acid such as boron trifluoride. The reaction temperature is approx. 20 to 170°C, particularly at the boiling point of the solvent used.
Utgangsstoffer med generell formel IV kan man f.eks. fremstille på følgende måte: Man går ut fra forbindelser med de tidligere definerte generelle formler II og omsetter disse med benzyloksyeddiksyrehydrazid til de tilsvarende 1-benzyl-oksymetyl-4H-s-triazol_/ 4, 3-a7./~l, 47benzodiazepiner som man spalter med hydrogenbromid til de tilsvarende 4H-s-triazol/_—4, 3-a//_ 1,4./ benzodiazepin-l-metanoler, disse alkoholer blir derpå oksydert med dimetylsulfoksyd i nærvær av dicykloheksylkarbodiimid og fosforsyre. Starting substances with general formula IV can be e.g. prepared in the following way: One starts from compounds with the previously defined general formulas II and converts these with benzyloxyacetic acid hydrazide to the corresponding 1-benzyl-oxymethyl-4H-s-triazol_/ 4, 3-α7./~1, 47benzodiazepines which cleaves with hydrogen bromide to the corresponding 4H-s-triazole/_—4, 3-a//_ 1,4./ benzodiazepine-l-methanols, these alcohols are then oxidized with dimethylsulfoxide in the presence of dicyclohexylcarbodiimide and phosphoric acid.
Oksydasjonen av de fremstilte forbindelser med generell formel I til deres 5-oksyder ble beskrevet i tilknyt-ning til første metode. The oxidation of the prepared compounds of general formula I to their 5-oxides was described in connection with the first method.
I henhold til en tredje fremgangsmåte i henhold According to a third method according to
til oppfinnelsen får man forbindelser med generell formel I, for the invention, compounds of general formula I are obtained,
deres 5-oksyder eller addisjonssalter med uorganiske eller organiske syrer, idet man omsetter en forbindelse med generell formel'VII their 5-oxides or addition salts with inorganic or organic acids, reacting a compound of general formula'VII
hvor R^ og R^ har betydning som angitt under formel I med en reaktiv ester av en forbindelse med generell formel VIII where R^ and R^ have the meaning as indicated under formula I with a reactive ester of a compound of general formula VIII
hvor Ro nar betydning som angitt under formel I, ved kondensa-sjon, og om ønsket oksyderer det fremstilte reaksjonsproduktet til dets 5-oksyd eller overfører det til et addisjonssalt med en organisk eller uorganisk syre. where Ro has the meaning as indicated under formula I, by condensation, and if desired oxidizes the produced reaction product to its 5-oxide or transfers it to an addition salt with an organic or inorganic acid.
Som reaktiv ester av en forbindelse med generell formel VIII kan man f.eks. benytte lavere alkylestere, særlig metyl- eller etylesteren. As a reactive ester of a compound of general formula VIII, one can e.g. use lower alkyl esters, especially the methyl or ethyl ester.
Omsetningen ifølge oppfinnelsen gjennomføres med fordel ved reaksjonstemperaturer mellom ca. 80 og l60°C i et The reaction according to the invention is advantageously carried out at reaction temperatures between approx. 80 and l60°C in a
inert oppløsningsmiddel. Som inerte oppløsningsmidler kan man særlig bruke hydrokarboner som toluen eller xylen, halogenerte hydrokarboner som klorbenzen, lavere alkanoler, fortrinnsvis inert solvent. Hydrocarbons such as toluene or xylene, halogenated hydrocarbons such as chlorobenzene, lower alkanols, preferably
slike som tilsvarer acetalgruppens alkanol, f.eks. etanol eller butanol, eteraktige væsker som dietylenglykoldimetyleter eller dioksan, og amider, særlig N,N,N',N',N",N"-heksametyl-fosforsyretriamid. Reaksjonstidene ligger mellom ca. 1 og 2 4 timer. those corresponding to the alkanol of the acetal group, e.g. ethanol or butanol, etheric liquids such as diethylene glycol dimethyl ether or dioxane, and amides, especially N,N,N',N',N",N"-hexamethyl phosphoric acid triamide. The reaction times are between approx. 1 and 2 4 hours.
Utgangsstoffer med generell formel VII er kjent; f.eks. 2-hydrazino-5-fenyl-7-klor-3H-l,4-benzodiazepin (sammenlign Kanji Meguro og Yutaka Kuwada, Tetrahedron Letters 1970, 4039). Andre forbindelser av denne type kan fremstilles analogt. Starting substances of general formula VII are known; e.g. 2-hydrazino-5-phenyl-7-chloro-3H-1,4-benzodiazepine (compare Kanji Meguro and Yutaka Kuwada, Tetrahedron Letters 1970, 4039). Other compounds of this type can be prepared analogously.
Oksydasjonen av de fremstilte forbindelser med generell formel I til deres 5-oksyder er beskrevet i forbindelse med første metode. The oxidation of the prepared compounds of general formula I to their 5-oxides is described in connection with the first method.
Forbindelser med formel I fremstilt ifølge oppfinnelsen blir deretter om ønsket overført til deres addisjonssalter på kjent måte med organiske eller uorganiske syrer. For eksempel tilsettes en oppløsning av forbindelse med generell formel I i et organisk oppløsningsmiddel den syre som er ønsket som spaltkompo-nent. Videre velger man til omsetningen organiske oppløsnings-midler hvor det dannede saltet er tungt oppløselig slik at det kan fraskilles ved filtrering. Slike oppløsningsmidler er f.eks. metanol, eter, aceton, metyletylketon, acetoneter, acetonetanol, metanoleter eller etanoleter. Compounds of formula I prepared according to the invention are then, if desired, transferred to their addition salts in a known manner with organic or inorganic acids. For example, a solution of a compound of general formula I in an organic solvent is added to the acid that is desired as a cleavage component. Furthermore, organic solvents are chosen for the reaction where the formed salt is poorly soluble so that it can be separated by filtration. Such solvents are e.g. methanol, ether, acetone, methyl ethyl ketone, acetone ether, acetone ethanol, methanol ether or ethanol ether.
For bruk som legemidler kan man i stedet for frie baser benytte farmasøytisk anvendelige syreaddisjonssalter, dvs. salter med slike syrer hvis anion er under de gitte doseringer ikke er giftige. Videre er det en fordel om saltene som skal brukes til legemidler er godt krystalliserbare og ikke eller bare lite hydroskopiske. Til slik saltdannelse med forbindelser med generell formel I kan-man f.eks. bruke saltsyre., hydrogenbromsyre, svovelsyre, fosforsyre, metansulfonsyre, etansulfonsyre, 2-hydroksy-etansulfonsyre eller perklorsyre. For use as pharmaceuticals, instead of free bases, pharmaceutically usable acid addition salts can be used, i.e. salts with such acids whose anion is below the given dosages are not toxic. Furthermore, it is an advantage if the salts to be used for pharmaceuticals are easily crystallisable and not or only slightly hygroscopic. For such salt formation with compounds of general formula I, one can e.g. use hydrochloric acid., hydrobromic acid, sulfuric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, 2-hydroxy-ethanesulfonic acid or perchloric acid.
De nye virksomme stoffer gis peroralt, rektalt eller parenteralt. Doseringen avhenger av administrasjonsveien, det aktive stoff, pasientens ålder og individuelle tilstand. De dag-lige doser av de frie baser, deres 5-oksyder eller deres farma-søytisk anvendelige salter av frie baser ligger mellom ca. 0,02 mg/kg og 4 mg/kg for pattedyr. Egnede doseringsenheter som dra-sjeer, tabletter, suppositorier eller ampuller inneholder fortrinnsvis 0,5-25 mg av et virksomt stoff ifølge oppfinnelsen. The new active substances are given orally, rectally or parenterally. The dosage depends on the route of administration, the active substance, the patient's age and individual condition. The daily doses of the free bases, their 5-oxides or their pharmaceutically usable salts of free bases lie between approx. 0.02 mg/kg and 4 mg/kg for mammals. Suitable dosage units such as dragees, tablets, suppositories or ampoules preferably contain 0.5-25 mg of an active substance according to the invention.

Til en oppløsning av 0,5 g (0,00126 mol) 6-fenyl-8-klor-4H-s-triazol/ 4,3-a//~l,47benzodiazepin-l-karboksaldehyd-dietylacetal i 3 ml aceton pluss 3 ml metanol settes 0,13 g (0,0013 mol) perklorsyre. Etter tilsetning av 5 ml petroleter utkrystalliserer saltet. Etter frafiltrering får man 6-fenyl-8-klor-4H-s-triazol-<_>/ 4,3-a7/~1,47benzodiazepin-l-karboksaldehyd-dietylacetal-perklorat som dekomponeres ved 250-265°. To a solution of 0.5 g (0.00126 mol) 6-phenyl-8-chloro-4H-s-triazole/4,3-a//~1,47benzodiazepine-1-carboxaldehyde-diethyl acetal in 3 ml of acetone plus 0.13 g (0.0013 mol) of perchloric acid is added to 3 ml of methanol. After adding 5 ml of petroleum ether, the salt crystallizes. After filtration, 6-phenyl-8-chloro-4H-s-triazole-<_>/ 4,3-α7/~1,47benzodiazepine-1-carboxaldehyde-diethylacetal-perchlorate is obtained which decomposes at 250-265°.
