Fremgangsmåte til fremstilling av
l-metyl-2-(alkylsulfonyl)-fenoksy-metyl)-5_nitro-imidazoler.
Gjenstand for søknad nr. 75 ^2 57 er l-alkyl-2-(fenoksymetyl)-5_nitro-iinidazoler med formel
1 2 hvori R betyr metyl eller etyl, R betyr trifluormetyl, tri-. klormetyl, nitro, cyan,.metylsulfonyl eller ■ etylsulfonyl og R betyr hydrogen, fluor, klor, brom, jod, trifluormetyl, tri-klormetyl, nitro eller cyan, fremgangsmåte til fremstilling av disse forbindelser, farmasøytiske"midler som inneholder dem og deres anvendelse. Gjenstand for tilleggssøknaden er l-metyl-2-(fenoksymetyl)-5_nitro-imidazoler med formel
hvori R betyr nitro, cyan, metylsulfonyl eller etylsulfonyl og R betyr metyl eller halogen samt fremgangsmåte til fremstilling av disse forbindelser, farmasøytiske "midler som inneholder dem og deres anvendelse.
I videreutviklingen av gjenstanden for søknad nr.
75 ^2 57 er det nå funnet en fremgangsmåte til fremstilling av l-alkyl-2-(fenoksymetyl)-5-nitro-imidazoler med formel I
1 2 hvori R betyr metyl, R betyr metylsulfonyl eller etylsulfonyl og R^ betyr hydrogen, metyl eller halogen som fluor, klor, brom eller jod, idet denne fremgangsmåte erkarakterisert vedat 1-■ metyl-2-(fenoksymetyl)-5-nitro-imidazoler med formel II
hvori A betyr et svovelatoirr eller en sulfoksydgruppe (-S0-),
R betyr metyl eller etyl, R"<*>"betyr metyl og R^ betyr hydrogen, metyl eller halogen,som fluor, klor, brom eller jod, oksyderes.
De som utgangsstoffer anvendte 1-mety1-2-(fenoksy-metyl )-5-nitro-imidazoler med formel II er gjenstand for søknad nr. 76 24 23. De kan fåes av l-metyl-2-klormetyl-5-nitro-imidazol (oppnåelig ifølge DOS 1.595-929 og DOS 1.470.'102) og eventuelt substituert alkylmerkaptofenoler eller alkylsulfinyl-fenoler (oppnåelig av de tilsvarende merkaptofenoler og dialkyl-sulfat og eventuelt deretter oksydasjon med perbenzosyre) i dimetylformamid og i nærvær av kaliumkarbonat.•
Som utgangsstoTfer med formel II kommer det eksempelvis på tale: 1-mety1-2-(4-metyltio-fenoksymetyl)-5-nitro-imidazol 1-mety1-2-(4-etyltio-fenoksymetyl)-5-nitro-imidazol 1-mety1-2-(3-metyl-4-metyltio-fenoksymetyl)-5-nitro-imidazol 1-mety1-2-(3~mety1-4-etyltio-fenoksymetyl)-5-nitro-imidazol l-metyl-2-(3~fluor-, -klor-, -brom-, -jod-4-metyltio-fenoksy-metyl )-5-nitro-imidazol
l-metyl-2-(3~fluor-, -klor-, -brom-, -jod-4-etyltio-fenoksy-metyl ) -5-nitro-imidazol
l-metyl-2-(4-metylsulfinyl-fenoksymetyl)-5-nitro-imidazol l-metyl-2-(4-etylsulfinyl-fenoksymetyl)-5-nitro-imidazol l-metyl-2-(3-mety1-4-metylsulfinyl-fenoksymetyl)-5-nitroimidazol
l-metyl-2- (3-mety1-4-etylsulf inyl-f enoksymetyl) - 5-nitro-imidazol l-metyl-2-(3~fluor-, -klor-, -brom-, -jod-4-metylsulfinyl-fenoksymetyl)-5-nitro-imidazol
l-metyl-2-(3-fluor-, -klor-, -brom-, -jod-4-etyIsulfinyl-fenoksymetyl)-5-nitro-imidazol.
Til oksydasjonen anvendes hensiktsmessig en- eller to ganger molare mengder av et oksydasjonsmiddel. Ofte kan det fortrinnsvis anvendes et overskudd av oksydasjonsmidlet. Anvender man som utgangsstoffer de tilsvarende sulfider (A = -S-
i formel II), så krever man minst to molekvivalenter oksydasjonsmiddel. Anvender man som utgangsstoff de tilsvarende sulfoksyder (A = -SO--i formel II), så trenger man en molekvi-valent oksydasjonsmiddel.
Som oksydasjonsmiddel kommer det eksempelvis på
tale hydrogenperoksyd eller persyrer, som f.eks. pereddiksyre, pertrifluoreddiksyre, klorperbenzosyre, spesielt 3-klorperbenzosyre, salpetersyre, kromsyre og deres salter, kromsyreanhydrid, permanganater, hypokloriter, klorater, perklorater, perjodater og nitrogenoksyder, spesielt dinitrogentetroksyd.
Oksydasjonsreaksjonene gjennomføres - fortrinnsvis i
et oppløsnings- eller fordelingsmiddel.
Herved egner det seg spesielt slike .oppløsningsmidler som ikke angripes" av oksydasjonsmidlet, som f,eks. eddiksyre, trifluoreddiksyre. Ved anvendelse av perbenzosyre egner det seg også metylenklorid og kloroform som oppløsningsmiddel.
OksydasJ onsreaksj onene gj ennomf øre.s vanligvis ved temperaturer mellom 0r-og 100°C, spesielt ved 40-60°C. Reaksjons-tidene utgjør.alt etter reaksjonsbetingelsene få minutter til noen timer.
Isoleringen av fremgangsmåteproduktene foregår ved fortynning av reaksjonsoppløsningen med vann under samtidig utfelling eller ved inndampning av det organiske oppløsningsmiddel i vakuum.. Eventuelt kan det foregå en rensning ved omkrystalli-sering fra et egnet oppløsningsmiddel eller oppløsningsmiddel-blanding.
Eksempel 1. 1- me t y 1- 2 - ( 4 - me t y 1 su 1 f ony 1- f enoks yrne tyl) -' 5- ni ' tr o- imi' d' a' z" o' l,
27,9 g (0,1 mol) l-metyl-2-(4-metyltio-fenoksy-metyl)-5-nitro-imidazol (smeltepunkt ll6°C) oppløses i 250 ml iseddik og under omrøring tildryppes ved værelsestemperatur
24,3 g (0,25 mol) 35%-ig hydrogenperoksyd. Ved den eksoterme reaksjon foregår temperaturøkning "til ca. 45°C. Derved opp-varmes ennu 1 time ved 60°C under omrøring. Etter avkjøling til værelsestemperatur helles blandingen på 800 ml is/vann-blanding, utfellingen frasuges, vaskes med vann og omkrystalli-. seres fra isopropanol under aktivkulltilsetning. Man får så-ledes 29 g = 93% av det teoretiske l-metyl-2-(4-metyl-sulfonyl-fenoksymetyl)-5-nitro-imidazol i form av gulaktige krystaller med et smeltepunkt 157°C.
Istedenfor utgangsstoffet l-metyl-2-(4-metyltio-fenoksymetyl)-5-nitro-imidazdl kan det også anvendes det tilsvarende sulfoksyd, l-metyl-2-(4-metylsulfinyl-fenoksymetyl)-5-nitro-imidazol (smeltepunkt 130°C). Det er da nødvendig med anvendelse av halve mengden hydrogenperoksyd..
På samme måte kan det fremstilles: 1- metyl-2-(4-etylsulfonyl-fenoksymetyl)-5-nitro-imidazol, smeltepunkt 132°C ved oksydasj>on av l-metyl-2-(4-etyltio-fenoksy-metyl)-5-nitro-imidazol (smeltepunkt.90°C) eller l-metyl-2-(4-etylsulfinyl-fenoksymetyl)-5-nitro-imidazol (smeltepunkt 103°C).
l-metyl-2- (3-me ty 1-4-metylsulf onyl-f enoksymetyl)-5-nitro-imidazol, smeltepunkt l4l°C ved oksydasjon av 1-metyl-2- (3-metyl-4-metyltio-fenoksymetyl)-5-nitro-imidazol (smeltepunkt 108°C) eller l-metyl-2-(3-metyl-4-metylsulfinyl-fenoksy-, metyl)-5-nitroimidazol (smeltepunkt 121°C).
l-metyl-2-(3-metyl-4-etylsulfonyl-fenoksymetyl)-5-nitroimidazol, smeltepunkt 115°C ved oksydasjon av l-metyl-2-(3-metyl-4-etyltio-fenoksymetyl)-5-nitro-imidazol (smeltepunkt 80°C) eller-l-metyl-2-(3-metyl-4-etylsulfinyl-fenoksymetyl)-5-nitroimidazol (smeltepunkt 95°C).
