Description
Foreliggende oppfinnelse angår nye 5-halogensalicylsyrederivater for anvendelse som utgangsmaterialer ved fremstilling av terapeutisk virksomme N-(dialkylaminoalkyl)-2-alkoxy-4-amino-5-halogenbenzamider. Disse halogensalicylsyrederivater har den generelle formel:
hvor R er et hydrogenatom eller resten av en alifatisk karboxylsyre, og X er klor, brom eller fluor.
Disse nye forbindelser kan fremstilles ved at et alkali-eller jordalkalimetaUsalt av et 4-halogenfenolderivat av den generelle formel:
hvor R og X har de ovenfor angitte betydninger, omsettes med karbondioxyd med påfolgende behandling med en syre.
Eksempler på den ovenfor nevnte rest av en alifatisk karboxylsyre er acetyl, kloracetyl, methoxyacetyl, propionyl, bu-tyryl og valeryl.
Ved fremstillingen av de nye utgangsmaterialer kan man omsette alkali- eller j ordalka limeta Usaltet av 4-halogenfenyl-derivatet (II) med karbondioxyd og derefter behandle det erholdte produkt med en syre. Eksempler på anvendbare salter av 4-halogen-fenolderivatet (II) er natrium- og kaliumsaltet, magnesium- og kal-siumsaltet. Alkali- eller jordalkalimetallsaltene kan fremstilles ved omsetning av 4-halogenfenol-derivatet (II) med et alkalimeta11, et jordalkalimeta11, et alkalimetallhydroxyd, et jordalkalimeta11-hydroxyd, et alkalimetallkarbonat, et alkalimetallhydrid eller et jordalkalimetallhydrid. Når et alkalimetallhydrid eller et jord-alkalimetallhydroxyd omsettes med 4-halogenfenol-derivatet (II), er det fordelaktig å fjerne vann som er dannet under reaksjonen, fra reakspnsproduktet ved destillasjon, for dette anvendes i frem-gangsmåten. I andre tilfelle kan det erholdte alkali- eller jord-alkalimetallsalt av 4-halogenfenol-derivatet anvendes i fremgangs-måten uten å isolere det på forhånd.
Omsetningen med karbondioxyd kan utfores i fravær av opplosningsmiddel, men man kan også anvende et inert opplosningsmiddel såsom en alkohol (f.eks. methanol eller ethanol), benzen, toluen eller xylen. Reaksjonen utfores vanligvis under oppvarmning ved hoyt trykk. Den påfolgende behandling kan utfores under anvendelse av en syre, såsom saltsyre, svovelsyre, salpetersyre eller ed-diksyre. Under behandlingen kan acylaminogruppen hydrolyseres til en aminogruppe, alt efter arten av acylgruppen og reaksjonsbetin-gelsene.
Blant de benzamidderivater som kan fremstilles fra de nye utgangsmaterialer ifolge oppfinnelsen er N-(2-dialkylaminoalk-yl)-2-a lkoxy-4-amino-5-ha logenbenzamider som har utmerkede farma-kologiske egenskaper såsom analgetiske, spasmolytiske, sedative, narkotiske og antiemetiske egenskaper. sådan fremstilling kan utfores ved en totrins reaksjon som beskrevet i blant annet de bri-tiske patentskrifter nr. 1.019.781 og 1.159.938.
I de nedenstående eksempler vises i detalj hvordan de nye utgangsmaterialer kan fremstilles.
Eksempel 1
2,8 g 3-amino-4-klorfenol og 1,4 g vannfritt kaliumkarbonat blandes godt i en morter. Den erholdte blanding tilblandes
1,4 g vannfritt kaliumkarbonat i form av et granulat samt pimpsten i stykkform og anbringes i en autoklav. Karbondioxyd under et try trykk på 30 atmosfærer ledes inn i autoklaven ved 25°C, hvorpå reaksjonen utfores ved en temperatur mellom 152 og 158°C under et
trykk på 40 atmosfærer i 5 timer. Derefter utlutes reaksjordblan-dingen med vann. Det vandige ekstrakt surgjores med IO %'s saltsyre og gjores derefter svakt alkalisk med en vandig natriumbikar-bonatopplosning. Herved utfelles 4-amino-5-klor-salicylsyre. De utfeldte krystaller fraskilles ved filtrering og omkrystalliseres fra en liten mengde aceton. Man får 2,45 g rene krystaller med smeltepunkt 187,5 - 188,5°C. Utbytte: 65,5 %.

Eksempel 2
1,85 g 3-acetamido-4-klorfenol og 5 g vannfritt kaliumkarbonat blandes godt i en morter. Den erholdte blanding blandes med 4 g vannfritt kaliumkarbonat samt med pimpsten i stykkform og anbringes i en autoklav. I autoklaven ledes der inn karbondioxyd med et trykk på 30 atmosfærer, idet autoklavens indre holdes ved en temperatur på 25°C. Derpå utfores reaksjonen ved en temperatur på 180°C under et trykk på 42 atmosfærer i 20 minutter og derefter ved en temperatur på 155°C i 5 timer. Når reaksjonen er fullsten-dig, utlutes reaksjonsblandingen med vann. Det vandige ekstrakt noytra li seres med IO %'s saltsyre. Det herved utfeldte materiale fraskilles ved filtrering og utlutes med en vandig natriumbikarbo-natopplosning. Det uopplbselige materiale fraskilles ved filtrering, og filtratet nøytraliseres med saltsyre. De herved utskilte krystaller fraskilles ved filtrering og omkrystalliseres fra vandig methanol, hvorved man får 1,0 g 4-acetamido-5-klorsalicylsyre med smeltepunkt 242°C (spaltning). Utbytte: 43 %.
