Područje izuma Field of invention
Izum se odnosi na upotrebu skupine aril ureaze u tretiranju raf-om posredovanih bolesti i farmaceutske formulacije za upotrebu u toj terapiji. The invention relates to the use of the aryl urease group in the treatment of raf-mediated diseases and a pharmaceutical formulation for use in such therapy.
Pozadina izuma Background of the invention
Onkogen p21ras uveliko pridonosi razvoju i napretku humanih čvrstih i mutiranih u 30% svih humanih karcinoma (Bolton et al. Ann. Rep. Mađ. Chem. 1994, 29, 165-74; Bos.Cancer Res.1989, 49, 4682-9). Uobičajeni, nemutirani oblici,ras protein ključni je elemment signala transdukcijske kaskade direktno na receptor faktora rasta u svim tkivima (Avruch et al. Trends Bichem.sci. 1994, 19, 279-83). Bikemijski, ras je veza gunidin nukleotida u proteinu, i kruženje između aktiviranih GTP-veza i GTP-veza u preostalih oblika koji su precizno kontrolirani s ras' endogenom GTP-aze aktivnosti i drugih regulatora proteina. Kod ras mutanata u stanicama raka, endogene aktivnosti GTP-aze su olakšane i zato prijenos proteina, osnovni su signal rasta u daljnje efektore kao što je raf kinaza. To su okviri za rast stanica raka koje nose ti mutanti (Magnuson et al. Semin.Cancer Biol. 1994. 5, 247-53). Pokazalo se da inhibicijski učinak aktivnog ras-a inhibicijom raf kinaze daje znak za prikladan put administracije deaktiviranih protutijela za raf kinazu ili co-ekspresiju dominantnih negativnih raf kinaza ili dominantnih negativnih MEK podloga od raf kinaze, znak je za reviziju transformiranih stanica u normalan rast fenotipa (vidi: Daum et al Trends Biochem. Sci 1994, 19 474-80; Fridman et al. J.Biol.Chem 1994, 269, 30105-8 Kolch et al (Nature 1991, 349, 426-28) imaju i daljnje inhibicije raf ekspresije s neosjetljivim RNA zapriječi se stanična proliferacija u membranom udruženih onkogena. Ista inhibicija raf kinaze (s neosjetljivim oligodeoksinukleotidama) biti će u korelaciji in vitro i in vivo s inhibicijom rasta različitih tipova humanih tomora. (Monia et al., Nat.Med. 1996, 2 668-75). Oncogene p21ras greatly contributes to the development and progression of human solid and mutated in 30% of all human cancers (Bolton et al. Ann. Rep. Mag. Chem. 1994, 29, 165-74; Bos.Cancer Res.1989, 49, 4682-9 ). In its normal, unmutated form, the ras protein is the key element of the signal transduction cascade directly to the growth factor receptor in all tissues (Avruch et al. Trends Bichem.sci. 1994, 19, 279-83). Bichemically, ras is a bond of gunidine nucleotides in the protein, and cycling between activated GTP-bonds and GTP-bonds in the remaining forms is precisely controlled by ras' endogenous GTPase activity and other protein regulators. In ras mutants in cancer cells, the endogenous GTPase activities are facilitated and therefore the transfer of proteins, the basic growth signal to downstream effectors such as raf kinase. These are the frameworks for the growth of cancer cells carried by these mutants (Magnuson et al. Semin. Cancer Biol. 1994. 5, 247-53). It has been shown that the inhibitory effect of active ras by inhibiting raf kinase provides a sign for a suitable route of administration of deactivated antibodies for raf kinase or co-expression of dominant negative raf kinases or dominant negative MEK substrates from raf kinase, is a sign for revising transformed cells into a normal growth phenotype (see: Daum et al Trends Biochem. Sci 1994, 19 474-80; Fridman et al. J.Biol.Chem 1994, 269, 30105-8 Kolch et al (Nature 1991, 349, 426-28) have further inhibitions raf expression with insensitive RNA inhibits cell proliferation in membrane associated oncogenes. The same inhibition of raf kinase (with insensitive oligodeoxynucleotides) will be correlated in vitro and in vivo with growth inhibition of various types of human tumors. (Monia et al., Nat.Med. 1996, 2 668-75).
Sadržaj izuma Content of the invention
Predstavljeni izum osigurava supstancije koje su inhibitori enzima raf kinaze. Budući da je enzim daljnji efektor p21ras, inhibitori su korisni u farmaceutskim formulacijama za humanu u veterinarsku upotrebu gdje inhibiraju odgovarajućim načinom raf kinazu gdje je to indicirano, npr., u tretiranju tumora i/ili rasta kanceriznih stanica koji je povezan s raf kinazom. Osobito, supstancije su korisne u tretiranju humanih ili animalnih čvrstih tumora, tj. mišji rak, budući da progresija tih karcinoma ovisi o signalu ras proteina na transdukciju kaskade sumijivom tretmnu s prekidanjem kaskade, tj. inhibicijom raf kinaze. U suglasju sa supstancijama izuma koje su korisne za tretiranje raka, uključujući i solidne zloćudne tumore, kao što su na primjer karcinomi (pluća, gušterače, tireoidee, krvi i kolona) mileoidnih poremećaja(mileoidna leukemija) ili adenomi (zloćudni adenom kolona). The present invention provides substances that are inhibitors of the raf kinase enzyme. Since the enzyme is a downstream effector of p21ras, the inhibitors are useful in pharmaceutical formulations for human and veterinary use where they appropriately inhibit raf kinase where indicated, eg, in the treatment of tumors and/or cancerous cell growth associated with raf kinase. In particular, the substances are useful in the treatment of human or animal solid tumors, i.e. mouse cancer, since the progression of these cancers depends on the signal of the ras protein on the transduction of the cascade comparable to the treatment with the interruption of the cascade, i.e. the inhibition of raf kinase. In accordance with the substances of the invention that are useful for the treatment of cancer, including solid malignant tumors, such as for example carcinomas (lung, pancreas, thyroid, blood and colon) myeloid disorders (myeloid leukemia) or adenomas (malignant colon adenoma).
Zato predstavljeni izum omogućuje općeniti opis supstancija kao aril uree, uključujući i aril i heteroalril analoge, koji inhibiraju put raf kineze. Izum dalje omogućuje metode za tretiranje rafom posredovana bolesna stanja u ljudi ili sisavaca. Osim toga izum se direktno odnosi na supstancije koje inhibiraju enzime raf kinaze kao i na supstancije , formulacije i metode za tretiranje rasta kancerogenih stanica s raf kinazom gdje je supstancija formule I koja je aplikabilna ili njezina farmaceutski prihvatljiva sol. Therefore, the present invention allows for a general description of substances as aryl ureas, including aryl and heteroaryl analogs, which inhibit the raf kinase pathway. The invention further provides methods for treating raffa-mediated disease states in humans or mammals. In addition, the invention directly relates to substances that inhibit raf kinase enzymes, as well as to substances, formulations and methods for treating the growth of cancerous cells with raf kinase, where the substance of formula I is applicable or its pharmaceutically acceptable salt.

Reductions by the Alumino- and Borohydrides in Organic Synthesis; VCH Publichers: New York (1991)), ili korištenjem nula valentnih metala, kao što su Fe, Sn ili Ca, često u kiselom mediju. Postoje brojne metode za sintezu nitroarila (March. Advanced Organic Chemisty, 3rd Ed. ; John Wiley: New York (1985). Laroc.Comprehensive Organic Transformations, VCH Publishers: New York (1989)). Aniline substitution can be carried out using standard methods (March. Advanced Organic Chemisty, 3rd Ed.; John Wiley: New York (1985). Laroc. Comprehensive Organic Transformations, VCH Publishers: New York (1989)). As shown in Scheme I, aryl amines are commonly synthesized by reduction of nitroaryls using metals as catalysts, such as Ni, Pd, or Pt, and H2 or hydrides as transfer agents, such as formate, cyclohexadine, or borohydride (Rylander. Hydrogenation Methods; Academic Press: London, UK (1985)). Nitroaryls can also be directly reduced with a strong hydride source, such as LiAlH4 (Seyden-Penne. Reductions by the Alumino- and Borohydrides in Organic Synthesis; VCH Publishers: New York (1991)), or using zero-valent metals, such as Fe, Sn or Ca, often in an acidic medium. There are numerous methods for the synthesis of nitroaryls (March. Advanced Organic Chemisty, 3rd Ed. ; John Wiley: New York (1985). Laroc. Comprehensive Organic Transformations, VCH Publishers: New York (1989)).

Shema I Redukcija nitroarila u aril amine Scheme I Reduction of nitroaryls to aryl amines
Nitroarili uobičajeno se formiraju s elektrolitičkom aromatskom nitracijom korištenjem HNO3, ili nekim od alternativnih NO2- izvora. Nitroarili mogu se dalje poboljšati prije redukcije. Nitroarili mogu se supstituirati s Nitroaryls are commonly formed with electrolytic aromatic nitration using HNO3, or one of the alternative NO2- sources. Nitroaryls can be further refined before reduction. Nitroaryls can be substituted with

Potencijalnom ostatnom skupinom (npr. F, Cl, Br, itd.) mogu se podvrći reakciji supstitucije ili tretmanu s nukleofilima, kao što je tiolat (prikazan U Shemi II) ili peroksid. Nitroarili mogu se isto podvrći Ullman-ovom tipu reakcije spajanja (Shema II) A potential remaining group (eg, F, Cl, Br, etc.) can be subjected to a substitution reaction or treatment with a nucleophile, such as a thiolate (shown in Scheme II) or a peroxide. Nitroaryls can also undergo an Ullman-type coupling reaction (Scheme II).

Nitroarili mogu se podvrći tranziciji metala koristeći reakciju unakrsnog spajanja. Za primjer, nitroaril electrofili, kao što su nitroaril bromidi, jodidi ili triflati, postiže se unakrsnom reakcijom vezanja posredovanjem s paladijem s aril nukleofilima , kao što je arilborna kiselina (Suzuki reakcija, prikazana kasnije), ariltins (Stille reakcija) ili arilcink (Negishi reakcija) da se dobije biaril (5). Nitroaryls can undergo transition metals using a cross-coupling reaction. For example, nitroaryl electrophiles, such as nitroaryl bromides, iodides, or triflates, are achieved by palladium-mediated cross-coupling reactions with aryl nucleophiles, such as arylboronic acids (the Suzuki reaction, shown later), aryltins (the Stille reaction), or arylzincs (Negishi reaction) to give the biaryl (5).

Isto tako nitroarili ili anilini mogu se pretvoriti u odgovarajući arensulfonil klorid (7) obradom s klorsulfonskom kiselinom. Reakcija sulfonil klorida s izvorom fluorida, kao što je KF da se dobije sulfonil klorid (8). Reakcija sulfonil fluorida 8 s trimetilsilil trif luorometanom uz izvor fluorida, kao što je tris (dimetilamino) sulfonium difluorotrimetilsilikonata (TASF) vodi u odgovarajući trifluormetilsulfon (9). Alternativno, sulfonil klorid 7 može se reducirati na arenetiol (10), na primjer s cinkovim amalgamom. Reakcija tiol 10 s CHCIF2 u prisustvu baze daje difluormetil merkaptam (11), koji se može oksidirati u sulfon (12) s jednim od različitih oksidanata, uključujući CrO3-octeni anhidrid (Sedova et al.Zh.Org.Khim,1970, 6 (568). Likewise, nitroaryls or anilines can be converted to the corresponding arenesulfonyl chloride (7) by treatment with chlorosulfonic acid. Reaction of sulfonyl chloride with a fluoride source, such as KF, to give sulfonyl chloride (8). Reaction of sulfonyl fluoride 8 with trimethylsilyl trifluoromethane with a fluoride source such as tris(dimethylamino)sulfonium difluorotrimethylsiliconate (TASF) leads to the corresponding trifluoromethylsulfone (9). Alternatively, the sulfonyl chloride 7 can be reduced to the arenethiol (10), for example with zinc amalgam. Reaction of thiol 10 with CHCIF2 in the presence of a base affords the difluoromethyl mercaptam (11), which can be oxidized to the sulfone (12) with one of a variety of oxidants, including CrO3-acetic anhydride (Sedova et al.Zh.Org.Khim,1970, 6 ( 568).

Kao što je prikazano u shemi IV, ne-simetrične urea formacije mogu biti uključene u reakciju aril izocianata (14) s aril aminom (13). Heteroaril izocianat može se sintetizirati iz heteroarilamina obradom s fosgenom ili fosgenovom ekvivalentom, kao što je triklor metil klorformat (difosgen), bis(triklormetil) karbonat (trifosgen) ili N,N'-karbonil diimidazol (CDI). Izocianat se isto može derivirati iz dobro derivirane heterolitične karboksilne kiseline, kao što je ester, kiseli halid ili anhidrid od Curtius -tip pretvaranja. Ta reakcija deriviranja kiseline 16 je izvor azida, slijedeće pretvaranje da se dobije izocianat. Odgovarajuća karboksilna kiselina (17) isto može biti predmet Curtius-tipa pretvaranja koristeći difenilfosforil azida(DPPA) ili sličnog reagensa. As shown in Scheme IV, non-symmetric urea formations can be involved in the reaction of aryl isocyanate (14) with aryl amine (13). A heteroaryl isocyanate can be synthesized from a heteroarylamine by treatment with phosgene or a phosgene equivalent, such as trichloromethyl chloroformate (diphosgene), bis(trichloromethyl) carbonate (triphosgene), or N,N'-carbonyl diimidazole (CDI). The isocyanate can also be derived from a well-derivatized heterolytic carboxylic acid, such as an ester, acid halide, or anhydride by Curtius-type conversion. This acid derivatization reaction 16 is the source of the azide, following conversion to give the isocyanate. The corresponding carboxylic acid (17) can also be subjected to a Curtius-type conversion using diphenylphosphoryl azide (DPPA) or a similar reagent.

Tablete mogu biti nepresvućene ili mogu biti presvučene poznatim tehnikama da sprečavaju dezintegraciju i absorpciju u probavnom traktu i omogućavaju odgovarajuću aktivnost kroz duže razdoblje. Na primjer, materijal koji utječe na otpuštanje, mogu se koristiti, na primjer gliceril monostearat ili gliceril distearat. Te tvari mogu se pripremiti u krutom, brzo otpuštajućem obliku. The composition intended for oral use can be prepared by a suitable method known in the production of pharmaceutical preparations. Such a composition may contain one or more substances selected from solvents, sweeteners, aromas, color and preservatives so as to achieve a good palatability of the product. The tablets contain an active substance and a mixture of non-toxic pharmaceutically acceptable excipients suitable for the production of tablets. These excipients can be, for example, inert diluents, such as calcium carbonate, sodium carbonate, calcium phosphate or sodium phosphate, granulating and disintegrating agents, for example corn starch, or alginic acid, binders, for example magnesium stearate, stearic acid or talc. Tablets can be uncoated or they can be coated using known techniques to prevent disintegration and absorption in the digestive tract and enable adequate activity over a longer period. For example, a material that affects the release can be used, for example glyceryl monostearate or glyceryl distearate. These substances can be prepared in a solid, quick-release form.
Formulacije za oralnu upotrebu mogu biti predstavljene u tvrdim želatinoznim kapsulama u kojima je aktivna tvar pomiješana s inertnim krutim diluentom, na primjer, kalcijev karbonat, kalcijev fosfat, kaolin, ili u mekim želatinoznim kapsulama gdje je aktivna tvar pomiješana s vodom ili uljnim medijem, na primjer uljem kikirikija, tekućim parafinom ili maslinovim uljem. Formulations for oral use may be presented in hard gelatin capsules in which the active substance is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate, kaolin, or in soft gelatin capsules in which the active substance is mixed with water or an oily medium, on for example with peanut oil, liquid paraffin or olive oil.

Aqueous suspensions contain active substances in a mixture with an excipient suitable for the production of aqueous suspensions. Such an excipient is a suspending agent, for example sodium carboxymethylcellulose, methylcellulose, hydroxypropyl methylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; Dispersing and wetting agents may also be natural phosphatides, for example lecithin, or thickening agents or alkylene oxides of fatty acids, for example polyoxyethylene stearate, or thickening agents for ethylene oxide products with long chain aliphatic alcohols, for example heptadecaethylene oxyethanol, or ethylene oxide thickeners with partial esters of fatty acids and hexitol such as polyoxyethylene sorbitol monooleate, or thickeners of ethylene oxide with partial esters of fatty alcohol and hexitol anhydride, for example polyethylene sorbitan monooleate. Aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring matter, one or more flavors, and one or more sweeteners, such as sugar or saccharin.
Vodotopivi prašci i granule koji su prikladni za pripremanje vodenih suspenzija nakon dodavanja u vodu osiguravaju aktivnu tvar i smjesu sa sredstvima za raspršivanje ili vlaženje, sredstva za suspendiranje i jedan ili više konzervanasa. Odgovarajuća sredstva za raspršivanje i vlaženje i sredstvo za suspendiranje biti će izneseni kasnije u primjerima. Dodatni ekscipiensi, na primjer, zaslađivači, arome i boje, mogu biti prisutni. Water-soluble powders and granules suitable for the preparation of aqueous suspensions after addition to water provide the active substance and mixture with dispersing or wetting agents, suspending agents and one or more preservatives. Suitable dispersing and wetting agents and suspending agents will be set forth later in the examples. Additional excipients, for example, sweeteners, flavors and colors, may be present.
Supstancije također mogu biti formulirane u obliku ne-vodenih otopina, tj., uljnih suspenzija koje se mogu formulirati suspendiranjem aktivne tvari u biljnom ulju, na primjer, arahidno ulje, maslinovo ulje, sezamovo ulje, ulje kikirikija, ili mineralno ulje kao što je tekući parafin. The substances can also be formulated in the form of non-aqueous solutions, i.e., oil suspensions that can be formulated by suspending the active substance in a vegetable oil, for example, arachidonic oil, olive oil, sesame oil, peanut oil, or a mineral oil such as liquid paraffin.
Uljne suspenzije mogu sadržavati podloge, na primjer pčelinji vosak, kruti parafin ili cetilni alkohol. Zaslađivači kao sto su gore spomenuti, i arome mogu se dodati da se dobije dobra palatabilnost preparata. Sastav se može konzervirati dodavanjem antioksidanta kao što je askorbinska kiselina. Oil suspensions can contain supports, for example beeswax, solid paraffin or cetyl alcohol. Sweeteners such as those mentioned above, and aromas can be added to obtain a good palatability of the preparation. The composition can be preserved by adding antioxidants such as ascorbic acid.
Farmaceutske kompozicije su isto predmet ovog izuma i mogu biti u tipu emulzije ulje-u- vodi. Uljna faza može biti od biljnog ulja, na primjer maslinovog ili arahidnog, ili mineralnog ulja, na primjer tekući parafin ili smjese istih. Odgovarajuća sredstava za emulgiranje mogu biti gume-prirodnog podrijetla, na primjer guma akacije ili gumeni tragakant, fosfetidi prirodnog porijekla, na primjer zrno soje, lecitin i esteri ili dijelovi estera nastali derivacijom masnih kiselina i heksitol anhidrida, na primjer sorbitan monooleat, i tvari za zgušćivanje od postranih djelomičnih estera s etilen oksidom, na primjer polioksietilen sorbitan monooleat. Emulzije mogu sadržavati i zaslađivače i arome. Pharmaceutical compositions are also the subject of this invention and can be in the oil-in-water emulsion type. The oil phase can be of vegetable oil, for example olive or arachid, or mineral oil, for example liquid paraffin or mixtures thereof. Suitable emulsifying agents can be gums of natural origin, for example gum acacia or gum tragacanth, phosphatides of natural origin, for example soybean, lecithin and esters or ester fractions derived from the derivatization of fatty acids and hexitol anhydride, for example sorbitan monooleate, and substances for thickening from side partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. Emulsions can also contain sweeteners and flavorings.
Sirupi i eliksiri mogu se formulirati sa zaslađivačima, na primjer glicerolom, propilen glikolom, sorbitolom ili laktoze. Neke formulacije mogu sadržavati i sredstva za ublažavanje, konzervanse i arome i boje. Syrups and elixirs can be formulated with sweeteners, for example glycerol, propylene glycol, sorbitol or lactose. Some formulations may also contain emollients, preservatives, and flavors and colors.
Supstancije se isto mogu aplicirati i u obliku supozuitorija za rektalnu primjenu lijeka. Te kompozicije mogu se pripremiti miješanjem lijeka s odgovarajućim ekscipientom koji ne nadražuje, koji je krut na običnoj temperaturi a tekući na rektalnoj temperaturi i tamo se rastopi i u rektumu otpusti ljekovitu tvar. Takvi materijali obuhvaćaju kakao maslac i polietilen glikole. The substances can also be applied in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient, which is solid at ordinary temperature and liquid at rectal temperature and melts there and releases the medicinal substance in the rectum. Such materials include cocoa butter and polyethylene glycols.

Upozorenje: ovo je veoma opasna reakcija, potencijalno eksplozivna. Uz miješanje otopine 4-kloropiridina (10,0 mL) u N-metilformamidu (250 mL) na sobnoj temperaturi dodaje se H2SO4 (3.55 mL) koja generira vanjsku temperaturu. Ovoj smjesi se doda H2O2 (30% wt u H2O, 17 mL) nakon FeSO4 · 7H2O (0.56 g) generira dalje visoku temperaturu. Dobivena smjesa miješa se 1 sat u mraku na sobnoj temperaturi, zatim se polako zagrijava kroz 4 sata do 45°C. Kada se prestanu mjehurići dizati, reakcija je zagrijana na 60°C kroz 16 h. Dobije se tamna neprozirna smeđa otopina koju se razrijedi s H2O (700 mL) zatim s 10% otopinom NaOH (250 mL). Dobivena smjesa se ekstrahira s EtOAc (3x500 mL). Organska faza posebno se ispere sa zasićenom otopinom NaCl (3x150 mL), potom se kombinira sušenje(MgSO4) preko sloja silika gela uz dodatak EtOAc. Nastalo smeđe ulje purificira se kolonskom kromatografijom (gradient od 50% EtOAc/50% heksana do 80% EtOAc/20% heksana). Dobiveno žuto ulje kristalizira se na 0°C kroz 72 h i dobije se 4-klor-N-metil-2-piridinkarboksamid (0.61 g, 5.3%): TLC (50% EtOAc/50% heksan) Rf 0.50; 1H-NMR (CDCl3) δ 3.04 (d, J=5.1 Hz, 3H), 7.43 (dd, J=5.4, 2.4 Hz, 1H), 7.96 (br s, 1H), 8.21 (s, 1H), 8.44 (d, J=5. 1 Hz, 1H), C1-MS m/z 171 ((M+H)+). Warning: this is a very dangerous reaction, potentially explosive. While stirring a solution of 4-chloropyridine (10.0 mL) in N-methylformamide (250 mL) at room temperature, H2SO4 (3.55 mL) is added, which generates an external temperature. To this mixture was added H2O2 (30% wt in H2O, 17 mL) after FeSO4 · 7H2O (0.56 g) generated a further high temperature. The resulting mixture is stirred for 1 hour in the dark at room temperature, then it is slowly heated over 4 hours to 45°C. When the bubbles stop rising, the reaction is heated to 60°C for 16 h. A dark opaque brown solution is obtained which is diluted with H2O (700 mL) then with 10% NaOH solution (250 mL). The resulting mixture was extracted with EtOAc (3x500 mL). The organic phase is washed separately with a saturated NaCl solution (3x150 mL), then combined with drying (MgSO4) over a layer of silica gel with the addition of EtOAc. The resulting brown oil is purified by column chromatography (gradient from 50% EtOAc/50% hexanes to 80% EtOAc/20% hexanes). The resulting yellow oil was crystallized at 0°C for 72 h to give 4-chloro-N-methyl-2-pyridinecarboxamide (0.61 g, 5.3%): TLC (50% EtOAc/50% hexane) Rf 0.50; 1H-NMR (CDCl3) δ 3.04 (d, J=5.1 Hz, 3H), 7.43 (dd, J=5.4, 2.4 Hz, 1H), 7.96 (br s, 1H), 8.21 (s, 1H), 8.44 ( d, J=5.1 Hz, 1H), C1-MS m/z 171 ((M+H)+).

Korak 1: Sinteza 3-klor-4-(2,2,2-trifluoracetilamino) fenola Step 1: Synthesis of 3-chloro-4-(2,2,2-trifluoroacetylamino)phenol
Željezu (3.24 g, 58.00 mino l) uz miješanje doda se TFA (200 mL). Toj gustoj smjesi doda se 2-klor-4-nitrofenol (10.0 g, 58 mmol) i trifluorocteni anhidrid (20 mL). Ta siva gusta smjesa miješa se na sobnoj temperaturi 6 dana. Željezo se odfiltrira iz otopine i dobiveni materijal se koncentrira pod smanjenim tlakom. Preostala siva krutina se disolvira u vodi (20 mL). Nastaloj žutoj otopini doda se zasićena otopina NaHCO3 (50 mL). Krutina koja je precipitirala u otopini odstrani se. Filtrat se polako hladi s otopinom natrijeva bikarbonata sve dok s produkt jasno ne odvoji od otopine (određuje se upotrebom cjevčica koje se podižu). Slabo tamno žuta otopina ekstrahira se s EtOAc (3X125 M1). Dobiveni organski sloj ispere se zasićenom otopinom NaCl (125 M1), osuši s (MgSO4) i koncentrira pod smanjenim tlakom. 1H-NMR (DMSO-d6) indicira u omjer 1 : 1 nitrofenola početnog materijala i željenog produkta 3-klor-4-(2,2,2-trifluoracetilamino) fenola. Nepročišćeni materijal dobije se u slijedećem koraku daljnjom purifikacijom. TFA (200 mL) was added to iron (3.24 g, 58.00 min L) with stirring. To this thick mixture was added 2-chloro-4-nitrophenol (10.0 g, 58 mmol) and trifluoroacetic anhydride (20 mL). This gray thick mixture is stirred at room temperature for 6 days. The iron is filtered off from the solution and the resulting material is concentrated under reduced pressure. The remaining gray solid is dissolved in water (20 mL). A saturated solution of NaHCO3 (50 mL) is added to the resulting yellow solution. The solid that precipitated in the solution was removed. The filtrate is slowly cooled with sodium bicarbonate solution until the product clearly separates from the solution (determined by the use of riser tubes). The slightly dark yellow solution was extracted with EtOAc (3X125 M1). The obtained organic layer is washed with saturated NaCl solution (125 M1), dried with (MgSO4) and concentrated under reduced pressure. 1H-NMR (DMSO-d6) indicates a 1:1 ratio of nitrophenol starting material and the desired product 3-chloro-4-(2,2,2-trifluoroacetylamino)phenol. Unpurified material is obtained in the next step by further purification.
