Description
Denne oppfinnelse angår en fremgangsmåte for fremstilling av nye substituerte 2-fenylamino-imidazolin-(2)-derivater med den generelle formel I
og deres fysiologisk forlikelige syreaddisjonssalter med verdi-fulle terapeutiske egenskaper.
I formel I betyr
og 1*2, som kan være like eller forskjellige, et fluor-,
klor- eller bromatom, eller en trifluormetylgruppe, og R- en alkylrest med opptil 4 C-atomer, en alkenylrest med opptil 4 C-atomer, en cyklopropylmetyl-, benzyl- eller tieny1-2-metyl-rest,, idet R^ og R2 ikke samtidig kan bety et kloratom når R-j betyr en alkylrest med l-4karbonatomer eller en benzylrest.
Forbindelsene med formel I fremstilles ved omsetning av
et 2-fenylamino-imidazolin-(2) med den generelle formel II
hvor R^ og R,, har de ovenfor angitte betydninger, med et halogenid med den generelle formel III
hvor Hal betyr et klor-, brom- eller jodatom, og R^ har de ovenfor angitte betydninger.
Omsetningen utføres fortrinnsvis i nærvær av et polart
eller upolart oppløsningsmiddel ved romtemperatur, idet hensiktsmessig natriumsaltene av forbindelsene med formel II omsettes med halogenidene med formel III. De spesielle reaksjons-
betingelser er i sterk grad avhengig av reaktiviteten av reaksjonskomponentene. Ved alkyleringen anbefales det å anvende halogenidet med den generelle formel III i overskudd og utføre omsetningen i nærvær av et syrebindende middel.
Utgangsforbindelsene med formel II er kjent fra litteraturen (se tysk off.skrift 2.457.979). Forbindelser med formel III kan fremstilles ved halogenering av de tilsvarende alkoholer.
De nye 2-fenylamino-imidazolin-(2)-derivater med den generelle formel I kan på vanlig måte overføres til sine fysiologisk forlikelige syreaddisjonssalter. Syrer som er egnet for saltdannelse er f.eks. saltsyre, bromhydrogensyre, jod-hydrogensyre, fluorhydrogensyre, svovelsyre, fosforsyre, salpetersyre, eddiksyre, propionsyre, smørsyre, kapronsyre, valeriansyre, oksalsyre, malonsyre, ravsyre, maleinsyre, fumarsyre, melkesyre, vinsyre, sitronsyre, eplesyre, benzoesyre, p-hydroksybenzoesyre, p-aminobenzoesyre, ftalsyre, kanelsyre, salicylsyre, askorbinsyre, metansulfonsyre, 8-klorteofyllin og lignende.
De nye forbindelser med den generelle formel I og deres syreaddisjonssalter har en sterk bradykard virkning og er derfor egnet til behandling av coronarlidelser. Innvirkningen på hjertefrekvensen undersøkes på kaniner og på spinalbedøvede rotter, samt på intakte, narkotiserte rotter. Doseringen ligger ved 0,1 til 80 mg, fortrinnsvis 1 til 30 mg.
Forbindelsene med formel I og deres syreaddisjonssalter kan også anvendes sammen med andre typer aktive stoffer. Egnede galeniske tilberedelsesformer er f.eks. tabletter, kapsler, stikkpiller, oppløsninger eller pulvere, og. for fremstilling av slike preparater kan man anvende de vanlig anvendte galeniske hjelpestoffer, bæremidler, sprengmidler eller smøremidler eller stoffer som medfører en depotvir-kning.
De følgende eksempler skal tjene til å illustrere oppfinnelsen ytterligere.

2-[ N- allyloksy- N-( 2- brom- 6- fluorfenyl) amino]- 2- imidazolin
5 g (0,016 mol) 2-[N-(2-brom-6-fluorfenyl)-N-(hydroksy)-amino]-2-imidazolin-hydroklorid oppløses sammen med 0,7 g natrium i 75 cm 3 absolutt etanol, og til oppløsningen settes 1,6 ml (ca. 115%) allylbromid.
Reaksjonsblandingen omrøres derefter i 1 time ved romtemperatur. Efter inndampning oppløser man det gjenværende residuum i fortynnet saltsyre (ca. IN) og ekstraherer den saltsure oppløsning (eterekstraktene kastes). Ved stigende pH-verdier (trinnvis alkalisering med 2N natronlut) foretas fraksjonert ekstraksjon med eter (også disse ekstrakter kastes).
Derefter alkaliseres med 5N NaOH, hvorved det utfelles meget rent 2-[N-allyloksy-N-(2-brom-6-fluorfenyl)amino]-2-imidazolin som et hvitt, amorft stoff. Utbytte efter avsugning, vasking med vann og tørring: 2,95 g (svarende til 58,3% av det teoretiske).
Smeltepunkt: 141°C.
På analog måte ble de følgende i tabellen angitte forbindelser syntetisert.
