Fremgangsmåte a) til c) er vanlige kjemiske fremgangsmåtetrinn. Fortrinnsvis gjennomføres fremgangsmåte a) til c) i et egnet
inert oppløsningsmiddel. Egnede oppløsningsmidler er for eksempel alkoholer, fortrinnsvis for reaksjon b) spesielt slike med 1 til 6 C-atomer som f. eks. metanol, étanol, i- og n-propanol, i-,

Omsetningen gjennomføres ved alle fremgangsmåtetrinn, vanligvis ved væreIsestemperatur. Alt etter reaksjonsdeltagernes reak-tivitet kan imidlertid være gunstig å gjennomføre reaksjonen under avkjøling resp. lavere temperaturer eller for høye temperaturer, f. eks. inntil det anvendte oppløsningsmiddel eller opp-løsning smiddelblandings tilbakeløpstemperatur. Reakjsons-temperaturen ligger i mange tilfeller ved -10°C til 25°C, fortrinnsvis ved 0°C til 20°C.
Et hensyn til en høy reaksjonshastighet av høyt utbytte er det vanligvis også fordelaktig ved reaksjonen av a) til c) hvor det som HX eller HY avspaltes klorhydrogen, og anvende syrebindere i.i tillegg til en base. Slike egnede baser er f. eks. alkali-karbonater som soda eller pottaske, alkalibikarbonater, som NaHCOg eller organiske aminer, spesielt tertiære organiske aminer som pyridin eiler tertiære alifatiske aminer med 2 til 9 C-atomer, som trimetylamin, trietylamin, tri-n-propylamin.

Ved fremstilling av forbindelsen med formel I etter fremgangsmåtetrinn a) til c) anvendes utgangskomponentene normalt i omtrent ekvimolare mengder. Hvis et utgangsamin også skal virke som syrebinder, anvendes amin i overskudd. Dette overskudd kan f. eks. være inntil 10 molar eller ennå større. Opparbeidelsen av blandingene foregår etter vanlige fremgangsmåte.
De for fremstilling av forbindelsene med formel I nødvendige utgangsprodukter med formel II til VII er kjent, eller kan lett fremstilles etter de for den respektive forbindelsesklasse kjente fremgangsmåter.

De substituerte piperazin-l-yl-eddiksyre-amider med formel
I danner med uorganiske eller organiske syrer syreaddisjonssalter. For dannelse av slike syreaddisjonsalter er det egnet uorganiske eller organiske syrer. Egnede syrer er eksempelvis: Klorhydrogen, bromhydrogen, naftalindisulfonsyre, spesielt nafta-lin-1,5-disulfonsyre, fosforsyre, salpetersyre, svovelsyre, oksal-syre, melkesyre, vinsyre, eddiksyre, salicylsyre, benzosyre, maursyre, propionsyre, pivalinsyre, dietyleddiksyre, malonsyre, ravsyre, pimelinsyre, fumarsyre, maleinsyre, eplesyre, sulfa-minsyre, fenylpropionsyre, glukonsyre, ascorbinsyre, nikotinsyre, isonikotinsyre, metansulfonsyre, p-toluensulfonsyre, sitronsyre, eller adipinsyre. Det foretrekkes farmakologisk godtagbare syreaddisjonssalter. Syreaddisjonssaltene fremstilles som vanlig ved forening av komponentene hensiktsmessig i et egnet oppløsning- eller fortynningsmiddél. Ved fremstilling av forbindelsene med formel I kan først syreaddisjonssaltene fremkomme under opparbeidelsen. Fra syreaddisjonssaltene kan de fri forbindelser med den generelle formel I hvis ønsket på kjent måte utvinnes, f. eks. ved oppløsning eller suspendering i vann og alkaligjøring, f. eks. ved natronlut og etterfølgende filtrering.
Forbindelsene fremstilt ifølge oppfinnelsen med formel I
og deres farmakologisk godtagbare syreaddisjonssalter har verdifulle farmakologiske egenskaper. På grunn av deres encefalotrope virkning kan de anvendes til middel til for-
bedring av cerebrale funksjoner, f.eks. hukommelse og bære-
evne. De er således en berikelse av farmasien, og lar seg anvende til behandling og forebyggelse av menneskelige sykdommer, spesielt ved bekjempelse og hindring av cerebrale insuffizienser, og ved forbedring av den intellektuelle ytelsesevne.
Forbindelsene med formel I og deres farmakologisk godtagbare syreaddisjonssalter kan derfor administreres på mennesker som helbredelsesmiddel alene, i blandinger med hverandre, eller i form av farmasøytiske tilberedninger, som muliggjør en enteral eller parenteral anvendelse, eller som som aktiv be-standdel, inneholder virksom dose av minst en forbindelse med formel I, eller et syreaddisjonssalt herav, ved siden av vanlige farmasøytisk ufarlige bære- og tilsetningsstoffer. Tilbered-ningene inneholder normalt ca. 0,5 til 9 0 vekt-% av den terapeutisk virksomme forbindelse. Legemidlene kan administreres oralt, f.eks. i form av piller, tabletter, lakktabletter, drageer, granulater, hård-og mykgelatinkapsler, oppløsninger, siruper, emulsjoner, eller suspensjoner, eller aerosolblandinger. Administreringen kan imidlertid også foregå rektalt, f. eks. i form av suppositorier, eller parenteralt, f. eks. i form av injeksjonsoppløsninger, eller perkutant, f. eks. i form av salver eller tinkturer.
Fremstillingen av de farmasøytiske preparater foregår på i og for seg kgent måte, idet det anvendes farmasøytiske inerte, uorganiske eller organiske bærestoffer. For fremstillingen av piller, tabletter, drageer, og hårdgelatinkapsler, kan man f. eks. anvende laktose, maisstivelse, eller derivater herav, talkum, stearinsyre, eller deres salter etc: Bærestoffer for mykgelatinkapsler og suppositorier er f. eks. fett, voks. halvfast og flytende polyoler, naturlige eller herdede oljer, etc. Som bærestoffer for fremstilling av oppløsninger og siruper egner det seg f.eks. vann, sakkarose, invert sukker, glukose, polyoler, etc. Bærestoffer for fremstilling av injeksjonsoppløs-ninger egner) det seg f.eks. vann, alkoholer, glycerol, polyoler, planteoljer etc.
De farmasøytiske preparater kan ved siden av virksomme stoffer
og bærestoffer dessuten inneholde tilsetningsstoffer som f. eks. fyllstoffer, drøye-, spreng-, binde-, glide-, fukte-, stabili-serings-, emulgerings-, konserverings-, søtnings-, farve-,
smaks- eller aromatiserings-, fordøyvings-, fortynningsmidler, pufferstoffer, videre oppløsningsmidler eller oppløsnings-formidlere, eller midler for oppnåelse av en depot effekt,
samt salter til endring av det osmotiske trykk, overtrekks-
midler eller antioksydanter. De kan også inneholde 2 eller flere forbindelser med formel I eller deres farmakologiske godtagbare syreaddisjonssalter, og dessuten vandige terapeutisk virksomme stoffer.
Slike andre terapeutiske virksomme stoffer er eksempelvis: 3-reseptorblokkerere, som f. eks. propanolol, pindolol, meto-prolol, antianginøse midler, som f.eks. karbokromen, molsidomin, beroligelsesmidler, som f. eks. barbitursyrederivater, 1,4-benzodiazepiner og meprobamat, diuretika, som f. eks. kloro-tiazid, hjertetoniserende midler, som f.eks. digitalispreparater, blodtrykkssen^ende midler, som f. eks. hydralazin, dihydralazin, prazosin, clonidin, Rauwolfia-alkaloider, midler som senker fettsyrespeilet i blod, som f. eks. bezafibrat, fenofibrat,
midler for tromboseprofylaks, som f. eks. en fenoprocoumon.
Forbindelsene med formel I og deres farmakologisk godtagbare syreaddisjonssalter og farmasøytiske preparater som inneholder forbindelsene med formel I eller deres farmakologisk godtag-
bare syreaddisjonssalter, som virksomt stoff, kan anvendes på mennesker ved bekjempelse resp. forebyggelse av sykdommer, spesielt til bekjempelse resp. forebyggelse av cerebral insuffiziens, og ved forbedring av den intellektuelle ytelsesevne. Doseringen
kan variere innen vide grenser, og er i hvert enkelt til-
felle å tilpasse den individuelle tilstand. Vanligvis er ved oral administrering en dagsdose fra ca. 1 til 1000 mg/kg, fortrinnsvis 5 til 8 00 mg/kg legemsvekt passe til oppnåelse av virksomme resultater,ved intravenøs applikasjon utgjør dagsdosen vanligvis ca. 5 til 500 mg/kg, fortrinnsvis 5 til 250 mg/kg legemsvekt. Dagsdosen oppdeles normalt, spesielt ved applikasjon av større mengder i flere, f. eks. 2, 3, eller 4 del-administreringer. Eventuelt kan det være nødvendig alt etter individuelle forhold å avvike fra den angitte dagsdose oppad eller nedad.
Undersøkelsen av forbindelsene ifølge oppfinnelsen på en cefalo-trop virkning, foregikk f. eks. ved den passive avoidanceprøve, som ble gjennomført som følger: Prøveapparatet er en lys-mørk-boks med elektrifiserbar gitter-bunn i den mørke del.
90 minutter etter administrering av kontroll- og preparatinjek-sjon, behandles erfarne hann-mus med scopolaminhydrobromid (3 mg/kg s.c). 5 minutter senere settes musene i boksens lyse del. Etter overveksling i den mørke del av boksen får de et for dem ubehagelig elektrisk fotsjokk. Etter 24 timer settes hver gang mus en gang i den lyse del av prøveapparatet, og opp-holdstiden måles (maks. 180 sekunder). Den signifikante virkning av prøvestoffet sammenlignet til kontrollgruppen, be-
regnes ved hjelp av medianprøve.
Som minimal effektiv dose MED av et preparat betegner man den
som viser en signifikant virkning mot scopolamin. De med en aktiv dose av preparat og scopolamin behandlede dyr viser en lang oppholdstid, likeledes de ikke med scopolaminbehandlede dyr, hvorimot et dyr med kontrollinjeksjon og scopolamin behandlede viser en kort oppholdstid. Sammenlignet ble det med-bestemt et med av piracetam. Ved undersøkelsen ble det opp-
nådd de i følgende tabell angitte verdier.
