Description
Fremgangsmåte til fremstilling av halogenpyridaziner.
Gjenstanden for foreliggende oppfin-nelse er fremstilling av 6-halogen-, særlig 6-klor-pyridaziner, som i 5-stilling har en fri eller funksjonelt avledet karboksylgruppe eller en acylrest. En funksjonelt avledet karboksylgruppe er f. eks. en forestret eller amidert karboksylgruppe og i første rekke cyangruppen. Med acylrest skal først fortrinsvis forstås acetylgruppen. Oppfinnelsen angår særlig slike 6-halogen-pyridaziner som i 3- og 4-stilling har lavere al-kyl, slik som metylrester, f. eks. 6-klor-5-cyan-3,4-dimetyl-pyridazin med formelen
De kan imidlertid også i disse stillinger ha andre rester slik som fenylrester.
De nevnte forbindelser har fungisid
virkning, f. eks. mot Epidermophyton og Microsporum, og amøbisid virkning, f. eks. mot Entamoeba Histolytica, og kan anven-des som legemiddel. De er også verdifulle som mellomprodukter.
Disse halogenpyridaziner lar seg fremstille etter i og for seg kjente fremgangsmåter. Således kan man behandle 6-oksy-pyridaziner, som i 5-stilling har en fri eller funksjonelt avledet karboksylgruppe eller en acylrest, med halogeneringsmidler. Som slike midler egner seg fortrinsvis halogen-idene av fosforsyre, slik som fosforoksyklorid, fosforpentaklorid eller fosforpenta-bromid. Omsetningen kan utføres i nær-vær eller fravær av fortynningsmidler eller
katalysatorer i åpent eller lukket kar under
trykk. Man arbeider fortrinsvis ved for-høyet temperatur.
De som utgangstoffer anvendte 6-oksy-pyridaziner er kjent eller lar seg fremstille etter i og for seg kjente fremgangsmåter.
Oppfinnelsen beskrives i de følgende eksempler. Mellom vektsdel og volumdel består det samme forhold som mellom gram og cm<3>. Temperaturene er angitt i Celsius-grader.
Eksempel 1:
20 vektsdeler 6-oksy-5-cyan-3,4-dime-tyl-pyridazin opphetes i en time i et bad på 100° sammen med 90 volumdeler fosforoksyklorid. Man avdamper overskudd av fosforoksyklorid i vakuum og tilsetter resten isvann. Den vandige oppløsning stilles
på pH = 7 med 2-n. natronlut, uttrekkes med kloroform, og kloroformresten omkry-stalliseres av ligroin. 6-klor-5-cyan-3,4-di-metyl-pyridazin fåes således i hvite krystaller med smeltepunkt = 81—82°. Utbytte 90 pst.
Eksempel 2:
Man oppheter 5 vektsdeler 6-oksy-5-lumdeler fosforoksyklorid i y2 time til 100°.
karbetoksy-3,4-difenyl-pyridazin og 30 vo-Deretter avdampes i vakuum for overskudd
åv fosforoksyklorid, resten opptas i isvann,
og den vandige oppløsning uttrekkes med eter. Eterresten krystalliserer man fra etylalkohol og får således 6-klor-5-karbet-oksy-3,4-difenyl-pyridazin med formelen
i hvite krystaller med smeltepunkt = 114°.
Utbytte 85 pst.
Eksempel 3:
20 vektsdeler 6-oksy-5-cyan-3,4-difenyl-pyridazin opphetes med 120 volumdeler fosforoksyklorid i y2 time til 100°. Man av-
damper deretter overskudd av fosforoksy-
klorid i vakuum og tilsetter resten isvann.
Den vandige oppløsning utrystes med eter,
eteren fordampes, og eterresten omkrystal-
liseres fra etylalkohol. Man får således 6-klor-5-cyan-3,4-difenyl-pyridazin med formelen
som hvite krystaller med smeltepunkt =
134—135°. Utbytte 75 pst.
Eksempel 4:
17,2 vektsdeler 6-oksy-5-karbetoksy-3,4-d;-(p-klorfenyl)-pyridazin og 100 volumdeler fosforoksyklorid opphetes y2 time til 100°. Man avdamper deretter overskudd av fosforoksyklorid i vakuum, tilsetter resten isvann og uttrekker med eter. Ved omkry-stallisasjon av eterresten fra etylalkohol får man 6-klor-5-karbetoksy-3,4-di-(p-klor-fenyl)-pyridazin med formelen
som hvite krystaller med smeltepunkt =- 137—139°. Utbytte 45 pst.
Eksempel 5:
Man oppheter 5 vektsdeler 6-oksy-5-acetyl-3,4-difenyl-pyridazin og 30 volumdeler fosforoksyklorid y2 time til 100°. Fosforoksyklorid avdampes deretter i vakuum,
resten tilsettes isvann og uttrekkes med kloroform. Etter avdestillasjon av kloro-formen krystalliserer 6-klor-5-acetyl-3,4 difenyl-pyridazin med formelen
fra etylalkohol som hvite krystaller med smeltepunkt = 166—167°. Utbytte 82 pst.
Claims (2)
1. Fremgangsmåte til fremstilling av 6-halogen-pyridaziner, som i 5-stilling har en fri eller funksjonelt avledet karboksyl-
eller acylgruppe, karakterisert ved at man behandler 6-oksy-pyridaziner, som i 5-stil-
ling inneholder en fri eller funksjonelt avledet karboksylgruppe eller en acylrest, med halogeneringsmidler, særlig kloreringsmid-ler.
