(54) Fremgangsmåde til fremstilling af heteroaromatiske urinstofderivater.
Den foreliggende opfindelse angår en særlig fremgangsmåde til fremstilling af heteroaromatiske urinstofderivater med formlen (I): R 1
Ar-N-CO-N (I) hvori Ar betegner en rest af en 5- eller 6-leddet heteroaromatisk ring med et eller to he te roatomer i form af nitrogen, oxygen eller svovl, R betegner hydrogen eller (C^-Cg) alkyl, R^ betegner (C^-Cg) alkyl, og ® R^ betegner (C^-Cg)alkyl, (C2~Cg)alkenyl eller (C^-Cg)alkoxy.
T- Heteroaromatiske urinstofderivater er nyttige som selektive herbi- cider. F.eks. er 5-alkylisoxazolylurinstoffer omhandlet i USA-patent
——J
nr. 4.062.861, og N-substituerede 1-(2-benzothiazolyl)urinstoffer er omhandlet i hollandsk fremlæggelsesskrift nr. 7.211.273, De kendte fremgangsmåder til fremstilling af disse urinstofderivater er imid-^ lertid mindre tilfredsstillende til industrielle formål.
2 U4011 F.eks. beskrives i USA-patentskriftet en fremgangsmåde til fremstilling af l,l-dimethyl-3-(5-t-butyl-3-isoxazolyl)urinstof, som omfatter, at 3-amino-5-t-butylisoxazol omsættes med N,N-dimethylcarbamoyl-chlorid i nærværelse af en base såsom pyridin. Denne fremgangsmåde lider af den mangel, at produktudbyttet uundgåeligt formindskes på grund af dannelsen af 1,3-bis(5-t-butyl-3-isoxazolyl)urinstof som et uønsket biprodukt.
Efter omhyggelige undersøgelser med henblik på udvikling af en forbedret fremgangsmåde til fremstilling af disse urinstofderivater (I) uden at sådanne biprodukter dannes, har det vist sig, at man ved anvendelse af en Lewis-syre i ovenstående reaktionssystem opnår, at omsætningen forløber selektivt og derved giver det største udbytte, og at udvalget af anvendelige udgangsaminer, Ar-NH-R (II) kan udvides til også at omfatte mindre reaktive heteroaromatiske aminer. Den foreliggende opfindelse er derfor med held blevet omsat til praksis.
Den foreliggende opfindelse angår således - som nævnt - en særlig fremgangsmåde til fremstilling af urinstofderivater med formlen (I): R R1
I /R
Ar-N-CO-N , (I) hvori Ar betegner en rest af en 5- eller 6-leddet heteroaromatisk ring, med et eller to heteroatomer i form af nitrogen, oxygen eller svovl, R betegner hydrogen eller (C^-Cg) alkyl, R"*" betegner (C^-Cg)-alkyl, og R2 betegner (C^-Cg)alkyl, (C2~Cg)alkenyl eller (C^-Cg)-alkoxy ved hvilken man omsætter en amin med formlen(II):
Ar-NH-R (II) hvori Ar og R har den ovenfor anførte betydning, med et carbamoyl-halogenid med formlen (III): X-CO-N (III)
^R
1 2 hvori X betegner et halogenatom, og R og R har den ovenfor anførte betydning, hvilken fremgangsmåde er ejendommelig ved, at omsætningen foretages i nærværelse af en Lewis-syre i et inert opløsningsmiddel.
Definitionen af ovenstående substituenter kan suppleres med følgende beskrivelse: 3 1UQ11
Den heteroaromatiske ring omfatter 3-isoxazolyl- (f.eks. 5-alkyl-3-isoxazolyl-, 5-phenyl-3-isoxazolyl-), 2-thiazolyl- (f.eks. 4-alkyl-2-thiazolyl-, 4,5-dialkyl-2-thiazolyl-), 3-isothiazolyl- (f.eks. 5-phenyl-3-isothiazolyl-), 2-benzothiazolyl- og 2-pyridylringe; alkyl-gruppen omfatter methyl, ethyl, propyl, i-propyl, butyl, i-butyl, t-butyl, pentyl og i-pentyl; alkenylgruppen omfatter allyl, butenyl, pentenyl og hexenyl; alkoxygruppen omfatter methoxy, ethoxy, propoxy og butoxy; halogen omfatter chlor, brom og iod, og Lewis-syren omfatter aluminiumchlorid, stannichlorid, titantetrachlorid, magnesiumchlo-rid og zinkchlorid, især aluminiumchlorid.
Omsætningen ifølge opfindelsen kan gennemføres i nærværelse af en Lewis-syre i et passende inert opløsningsmiddel (f.eks. benzen, toluen, xylen, chloroform, methylenchlorid, dichlorethan, trichlor-ethylen) under opvarmning fortrinsvis til omkring opløsningsmidlets kogepunkt. Mængden af carbamoylhalogenidet (III) i forhold til ud-gangsaminen (II) kan indstilles til ca. 1,0 til ca. 1,2 molækvivalent, fortrinsvis ca. 1,0 til ca. 1,1 molækvivalent. Forholdet mellem Lewis-syren og udgangsaminen (II) kan være ca. 1,0 til ca. 1,2 mol ækvivalent, fortrinsvis ca. 1,0 til ca. 1,1 molask vi valent.
Den industrielle fordel ved den foreliggende opfindelse i forhold til den kendte teknik er som følger: 1) Omsætningen giver kun det pågældende rene produkt i næsten kvantitativt udbytte uden sidereaktioner af betydning; 2) Omsætningens anvendelsesområde er tilstrækkelig bredt til, at der kan anvendes forskellige mindre reaktive heteroaromatiske aminer; 3) Fremgangsmåden er simpel at gennemføre, og slutproduktet kan let isoleres og renses.
Fremgangsmåden ifølge den foreliggende opfindelse illustreres hærmere i de følgende udførelseseksempler.
Eksempel 1 N,N-dimethylcarbamoylchlorid (7,91 g) og aluminiumchlorid (9,80 g) sættes til toluen (100 ml), og blandingen omrøres ved stuetemperatur i 30 minutter. Til denne blanding sættes 3-amino-5-t-butylisoxazol (9,81 g), og den opnåede blanding tilbagesvales i 6 timer under omrøring. Efter afkøling blandes reaktionsblandingen med vand, omrøres ved stuetemperatur og rystes med toluen. Det organiske lag inddampes til fjernelse af toluen, hvorved l,l-dimethyl-3-(5-t-butyl-3-isoxa-zolyl)urinstof (14,63 g) opnås. Udbyttet er 98,9%. Smeltepunktet af 4 144011 det farveløse krystallinske produkt er 119 til 120,5°C (efter om-krystallisation fra benzen).
