Foreliggende oppfinnelse angår en ny fremgangsmåte til fremstilling av benzodiazepinderivater med den generelle formel: og syreaddisjonssalter derav* hvor R-^ betyr hydrogen, ^-alkyl, C2_^-alkenyl, C^_^-alkynyl, eller en gruppe med formelen -cnH2n'R5' hvor n er et helt tall på 1 - 4 og R^ betyr halo gan, trifluormetyl, cyan, C-^y-cykloalkyl, C-^-alkoksy, C-^-alkyltio, C2_^-alkenyl-oksy, karbamoyl, C-L_Zf-alkyl-karbamoyl, acyloksy, C-L_^-alkylkarbonyl, fenyl eller fenyl substituert med halogen, nitro, trifluormetyl, C1_^-alkoksy, C-L_^-alkyl eller sulfamoyl, eller R^ betyr en gruppe med formelen: hvor Rg betyr hydrogen eller ^-alkyl og Ry betyr ^-alkyl, forutsatt at Rg og R^ sammen med det tilstbtende nitrogenatom kan danne en eventuelt med alkyl, hydroksyalkyl, alkoksyalkyl eller alkenyloksyalkyl substituert pyrrolidino-, piperidino-, piperazino-, alkylpiperazino-, alkyloksyalkyl-piperazino- eller morfolino-gruppe; R2 betyr hydrogen, halogen, C-^^-alkyl, ni tro, cyano, trifluormetyl, trifluormetoksy, di-(C1_Zf-alkyl)amino, piperidino, C-^^-alkoksy, C1_ ^-alkyl ti o, C-L_^-alkylsulfonyl, C-L_^-alkylsulfinyl, karbamoyl eller sulfamoyl; R^ betyr hydrogen, ni tro, C-^^-alkyl eller halogen; R^ betyr C-^^-alkyl, C^_y-cykloalkyl, cykloalkenyl, fenyl, fenyl substituert med halogen, nitro, trifluormetyl, C-^ ^-alkoksy, C1_^-alkyl eller sulfamoyl, fenyl-C-j_ ^-alkyl eller en pyridyl-, pyrimidyl-, pyridazinyl-, pyrazinyl-, tienyl-, furyl-, tiazol-, oksazoyl- eller indolylgruppe, hvilke grupper kan være substituert med halogen eller alkyl; Rg betyr hydrogen, C-^_^-alkyl, C1_^-alkoksy-C1_^-alkyl, C1_z+-alkyltio-C1_^-alkyl, fenyl, fenyl substituert med halogen eller C-^ 2-alkoksy, benzyl eller hydroksybenzyl, samt syreaddisjonssalter derav.
I forbindelser med formel I kan C-L_^-alkylgruppen f.eks. være metyl, etyl, n-propyl, isopropyl, n-butyl, isobutyl og ter-tiær butyl, nevnte C2_^-alkenylgrupper kan være grupper såsom allyl, butenyl (heri innbefattet forskjellige isomere) og lignende. Nevnte ^-alkynylgrupper er fortrinnsvis propargyl. C^-Cy-cykloalkyl-grupper innbefatter f.eks. cyklopropyl, cyklobutyl, cykloentyl, cykloheksyl og cykloheptyl, mens nevnte C-L_ ^-alkoksy gruppe r innbefatter f.eks. metoksy, etoksy, n-propoksy, isopropoksy, n-butoksy og tertiære butoksygrupper, mens nevnte halogenatom innbefatter
klor, brom, jod bg fluor.
Gruppen med formelen -^H^- representerer en rettkjedet eller forgrenet alkylengruppe med opptil 4 karbonatomer og innbefatter f.eks. metylen, etylen, 1-metyletylen, 2-metyletylen, tri-metylen, 1-metyltrimetylen og 2-metyltrimetylengrupper.
Når Rc representerer en acyloksygruppe, så innbefatter dette acetyloksy, propionyloksy, benzoyloksy, halogenbenzoyloksy, metoksybenzoyloksy, dimetoksybenzoyloksy, trimetoksybenzoyloksy, fenylacetyloksy,nlkotinoyloksy, isonikotinoyloksy eller lignende.

Andre substituenter i tillegg til de som er nevnt ovenfor kan eventuelt være tilstede i fenyl-gruppen uten at man derved kvalitativt forandrer egenskapene ved den foreliggende forbindelse.
Benzodiazepinderivater med formel (i) har utpregede effekter som beroligende midler, muskelavslappende midler, som antispasme- og antikrampemidler foruten som hypnotisk middel, og er fblgelig av stor viktighet, som medisiner.
Det er hittil blitt beskrevet flere framgangsmåter for fremstilling av disse benzodiazepinderivater. Det er f.eks. kjent hvordan man kan fremstille nevnte benzodiazepinderivater ved å oppvarme et o-aminofenylketon med et overskudd av glycinetylester-hydroklorid av pyridin, og hvis det er bnskelig, alkylere det re-sulterende 1-usubstituerte benzodiazepinderivat. ^L.H. Sternbach, et al.: Journal of Organic Chemistry, 27, 3788 (1962), Journal of Medicinal Chemistry, 8, 815 (1965^7- Denne fremgangsmåte krever imidlertid åt man oppvarmer reaksjonsblandingén til temperaturer med meget nær opplosningsmidiets kokepunkt, og det er ytterligere meget vanskelig å oppnå hoyt utbytte, og den er fplgelig ikke særlig godt egnet for kommersiell anvendelse i stor skala.
I motsetning til denne kjente fremgangsmåte har man nå relativt uventet funnet at benzodiazepinderivater med formel (I) lett og okonomisk kan fremstilles i meget hoyt utbytte.og med hby renhet ved å omsette et Orraminofenylketonderivat med formel (II) med et 2,5-dionderivat med formel (III). Foreliggende fremgangsmåte kan videre utfores ved romtemperatur eller under denne temperatur, og gir de foronskede benzodiazepinderivater i nesten kvanti-tative utbytter.
Det er en hensikt ved foreliggende oppfinnelse å til-veiebringe en ny fremgangsmåte for fremstilling av benzodiazepinderivater .
Foreliggende oppfinnelse tilveiebringer en fremgangsmåte for fremstilling av benzodiazepinderivater og salter av disse med forannevnte formel (i), og denne fremgangsmåte er kjennetegnet ved at man behandler et aminofenylketonderivat med formelen
hvor R-p R2, R^ og R4 er som definert ovenfor, med et 2,5-dionderivat med formelen:
hvor Rg er som definert ovenfor, og X representerer oksygen eller svovel.
Ved fremstilling av benzodiazepinderivater ifblge foreliggende oppfinnelse kan aminofenylketonderivater med formel (II) behandles met et 2,5-dionderivat med formel (III) i et opplbsningsmiddel eller i en blanding av opplosningsmidler. Egnede opplosningsmidler innbefatter f.eks. kloroform, karbontetraklorid, metylenklorid, etylenklorid, eter,' diisopropyleter, tetrahydrofuran, dioksan, vann, metanol, etanol, dimetylformamid, dimetylsulfoksyd, eller blandinger av disse. Reaksjonen utfores vanligvis i nærvær av en syre. Som nevnte syre kan man i dette henseende anvende saltsyre, hydrogenbromid, svovelsyre, fosforsyre, polyfosforsyrer, bortrifluorid eller paratoluensulfonsyre. Reaksjonen utfores ved temperaturer fra -25 til +120°C, fortrinnsvis fra ca. 0 til ca. 30°C. Man kan hvis det er onskelig også anvende temperaturer uten-for det forannevnte området, men dette er mindre foretrukket. I de fleste tilfeller kan reaksjonen utfores ved romtemperatur eller lavere. Trykk er ikke kritisk, og fremgangsmåten kan utfores ved atmosfærisk trykk, subatmosfærisk eller overatmosfærisk trykk. Hvis det er onskelig, kan fremgangsmåten utfores i en inert atmosfære, f.eks. i en atmosfære av nitrogen, argon eller lignende.
Skjbnt molforholdet mellom 2,5-dionderivatet og amino-fenylketonderivatet ikke er kritisk, så er det foretrukket å anvende minst stbkiometriske mengder av reaktantene. I de fleste tilfeller er det foretrukket å anvende et overskudd av 2,5-dionderivatet.
Hvis det er onskelig, kan reaktantene oppvarmes i et egnet opplbsningsmiddel, f.eks. dimetylsulfoksyd,dimetylformamid eller lignende, for derved å fullfore reaksjonen.
Benzodiazepinderivater fremstilt ifblge forannevnte fremgangsmåte'kan dessuten isoleres i form av et syreaddisjonssalt ved en behandling med en syre, f.eks. en mineralsyre såsom saltsyre, svovelsyre, salpetersyre eller fosforsyre, eller en organisk syre, såsom maleinsyre, fumarsyre, ravsyre, maursyre eller eddiksyre.
Fblgende eksempler illustrerer oppfinnelsen.

Eksempel 36
En opplbsning av 0,7 g 2-(cyanometylamino)-5--klorbenzo-fenon i tbrr metylenklorid ble tilsatt 0,7 g oksazolid-2»5-dion.
Blandingen ble så tilsatt 7 ml eter mettet med hydrogenklorid
ved en temperatur under ca. 5°C Blandingen ble rort ved; 0 - 5°C og deretter ved romtemperatur. Den ble deretter helt over i isvann,
nøytralisert med vandig ammoniakk og ekstrahert med metylenklorid.
De samlede metylenkloridekstrakter ble torket over natriumsulfat, opplbsningsmidlet ble så fjernet, hvorved man fikk et residuum bestående av l-cyanometyl-5-fenyl-7-klor-l,3-dihydro-2H-1,4-benzodiazepin- 2-on. Dette residuum ble opplost i eter og behandlet med eter mettet med hydrogenklorid for fremstilling av hydrokloridet. Omkrystallisasjon fra kloroform-isopropylalkohol gir 1-cyanometyl-5-fenyl-7-klor-l,3-dihydro-2H-l,4-benzodiazepin-2-on dihydroklorid,
