til fremstilling av hittil ukjente etere av for the production of hitherto unknown ethers of
salicylsyreamid av den alminnelige formel: salicylic acid amide of the general formula:
i hvilken Alkylen betegner en lavere alkylengruppe og Ri og R- betyr vannstoff eller lavere alkyl eller tilsammen med N en mettet heterocyklisk ring, for eksempel en piperidin-, morfolin- eller pyrrolidinring, eller syresalter eller kvaternære ammoniumsalter av disse etere. Disse forbindel-ser har vist seg å være særdeles verdifulle analgetika og antipyretika. Fremgangsmåten ifølge oppfinnelsen er karakterisert ved at salicylsyreamid eller et O-salt av dette omsettes med en reaksjonsdyktig ester av en alkohol av den alminnelige formel i hvilken Alkylen har den ovenfor angitte betydning, og Z har samme betydning som in which the alkylene denotes a lower alkylene group and Ri and R- mean hydrogen or lower alkyl or together with N a saturated heterocyclic ring, for example a piperidine, morpholine or pyrrolidine ring, or acid salts or quaternary ammonium salts of these ethers. These compounds have proven to be particularly valuable analgesics and antipyretics. The process according to the invention is characterized in that salicylic acid amide or an O-salt thereof is reacted with a reactive ester of an alcohol of the general formula in which Alkyl has the above meaning, and Z has the same meaning as
eller betyr en reaktiv estergruppe, or means a reactive ester group,
hvilken siste gruppe ved omsetningspro-duktets reaksjon med et amineringsmiddel which last group by the reaction of the reaction product with an aminating agent
omdannes til en primær, sekundær eller converted into a primary, secondary or
tertiær aminogruppe eller til en kvaternær tertiary amino group or to a quaternary
ammoniumsaltgruppe, hvoretter den oppnådde eters aminogruppe eventuelt alky- ammonium salt group, after which the amino group of the obtained ether optionally alkyl-
leres ytterligere og omdannes til en aminsaltgruppe. is read further and converted into an amine salt group.
Som reaksjonsdyktig ester kan det ved fremgangsmåten anvendes for eksempel en halogenvannstoff-ester, en alifatisk eller aromatisk sulfon- eller svovelsyre-ester eller en alkyl- eller klorkullsyre-ester. Som amineringsmiddel anvendes det for eksempel ammoniakk, en primær, sekundær eller tertiær amin eller heksametylentetramin. Den ytterligere alkylering eller aralkyle-ring av den oppnådde eters aminogruppe kan gjennomføres på i og for seg kjent måte, for eksempel ved omsetning med en reaksjonsdyktig ester eller ved reduktiv alkylering med et aldehyd og maursyre eller med et aldehyd eller en keton og kata-lytisk aktivert hydrogen. Aminsaltenes dannelse kan gjennomføres med organiske eller uorganiske syrer, fortrinnsvis klor-vannstoffsyre. A reactive ester can be used in the process, for example, a hydrogen halogen ester, an aliphatic or aromatic sulfonic or sulfuric acid ester or an alkyl or carbonic acid ester. As an aminating agent, ammonia, a primary, secondary or tertiary amine or hexamethylenetetramine is used, for example. The further alkylation or aralkylation of the amino group of the obtained ether can be carried out in a manner known per se, for example by reaction with a reactive ester or by reductive alkylation with an aldehyde and formic acid or with an aldehyde or a ketone and catalytic activated hydrogen. The formation of the amine salts can be carried out with organic or inorganic acids, preferably hydrochloric acid.
Ved en modifisert utførelsesform for fremgangsmåten ifølge oppfinnelsen gjen-nomføres salicylsyreamidets foretring med en forbindelse av den alminnelige formel In a modified embodiment of the method according to the invention, the etherification of the salicylic acid amide is carried out with a compound of the general formula
i hvilken Z eller Alkylen-Z er erstattet med in which Z or Alkylene-Z is replaced by
a) en alkylengruppe, a) an alkylene group,
b) en-cyangruppe, b) en-cyano group,
c) en-oksogruppe eller c) en-oxo group or
d) en dibénzyl-, dibensylhydryl- eller benzyl-alkyl-aminogruppe, hvoretter denne gruppe i den dannede eter ved a) tiileiring av åmimoniakk eller en primær eller sekundær amin, b) reduksjon eller reduktiv omsetning med en alkylamin, d) a dibenzyl, dibenzylhydryl or benzyl-alkyl-amino group, after which this group in the formed ether by a) addition of ammonia or a primary or secondary amine, b) reduction or reductive reaction with an alkylamine,
c) reduktiv aminering eller c) reductive amination or
d) hydrogenolyse d) hydrogenolysis
omdannes til en amino-, alkylamino-, aral-kylamino-, dialkylamino eller kvaternær ammoniumsaltgruppe. is converted to an amino, alkylamino, aralkylamino, dialkylamino or quaternary ammonium salt group.
I stedet for salicylsyreamid kan det ved de omhandlede fremgangsmåter også anvendes en salicylsyre-ester, hvis estergruppe etter foretringen ved reaksjon med et amideringsmiiddel omdannes til en syre-amidgruppe. Instead of salicylic acid amide, a salicylic acid ester can also be used in the methods in question, whose ester group is converted into an acid amide group after etherification by reaction with an amidating agent.
De ved fremgangsmåten ifølge oppfinnelsen oppnådde etere av salicylsyreamid og deres salter eller kvaternære ammoniumsalter utmerker seg ved at de er lett oppløselige i vann og allikevel tiar en sær-' deles god analgetisk og en god antipyretisk virkning og tåles godt av pasienter. Dette er overraskende, for hittil har innføringen av en vannoppløseliggj ørende gruppe i salicylsyreamid eller dets som analgetika an-vendbare derivater, som er O-Alkyl- eller N-alkyl-derivater, alltid ført til en nedsettel-se av forbindelsenes terapeutiske indeks. Det er således kjent at utskiftningen av salicylsyreamidets fenoliske vannstoffatom med en dietylamingruppe mere enn for-dobler forbindelsens giftighet, og at denne samme utskiftning hos kjernesubstituerte salicylsyreamlider også øker forbindelsenes giftighet og ytterligere nedsetter deres analgetiske virkning. Ved utskiftning av det fenoliske vannstoffatom av salicylsyreamid eller dets kjernesubstituerte derivater med alkylengrupper økes i noen tilfeller, for eksempel med etyl- eller allyl-gruppen, forbindelsenes analgetiske virkning noe, men forbindelsene tåles i rege-len mindre godt av pasientene, mens det ved utskiftning av samme vannstoffatom med en oksyalkylengruppe er blitt konstatert en nedgang av forbindelsenes analgetiske virkning. The ethers of salicylic acid amide and their salts or quaternary ammonium salts obtained by the method according to the invention are distinguished by the fact that they are easily soluble in water and nevertheless have a particularly good analgesic and a good antipyretic effect and are well tolerated by patients. This is surprising, because until now the introduction of a water-solubilizing group in salicylic acid amide or its derivatives usable as analgesics, which are O-Alkyl or N-alkyl derivatives, has always led to a reduction in the therapeutic index of the compounds. It is thus known that the replacement of the salicylic acid amide's phenolic hydrogen atom with a diethylamine group more than doubles the compound's toxicity, and that this same replacement in core-substituted salicylic acid amides also increases the compounds' toxicity and further reduces their analgesic effect. By replacing the phenolic hydrogen atom of salicylic acid amide or its core-substituted derivatives with alkylene groups, in some cases, for example with the ethyl or allyl group, the compounds' analgesic effect is somewhat increased, but the compounds are generally tolerated less well by the patients, while with replacement of the same hydrogen atom with an oxyalkylene group, a decrease in the compounds' analgesic effect has been observed.
Det ble ved forsøk med mus og rotter foretatt en sammenligning av giftigheten og den analgetiske virkning av In experiments with mice and rats, a comparison was made of the toxicity and the analgesic effect of

B. salicylic acid amide, which was used in the form of a 10 percent suspension in aqueous solution of gum arabic, and C. 2-ethoxybenzamide, which was also used in the form of a 10 percent suspension in aqueous solution of gum arabic rubber.
Det ble konstatert at forbindelsen A It was found that the compound A
ved subkutan administrasjon var mindre giftig enn forbindelsene B og C og ved peroral administrasjon ca. 7 pst. giftigere enn forbindelsen B og 7 pst. mindre giftig enn forbindelsen C. Ved peroral administrasjon var den analgetiske virkning av forbindelsen A nesten seks ganger så stor som den tilsvarende virkning av forbindelsen B og nesten dobbelt så stor som den tilsvarende virkning av forbindelsen C. Ved subkutan administrasjon var den analgetiske virkning av forbindelsen A ca. 25 pst. kraftige-re enn ved peroral administrasjon, miens on subcutaneous administration was less toxic than compounds B and C and on oral administration approx. 7% more toxic than compound B and 7% less toxic than compound C. Upon oral administration, the analgesic effect of compound A was almost six times as great as the corresponding effect of compound B and almost twice as great as the corresponding effect of compound C. When administered subcutaneously, the analgesic effect of compound A was approx. 25 percent more powerful than with oral administration, mean
den tilsvarende virkning av forbindelsene B og C ved denne form for administrasjon var ca. 10 pst. svakere enn ved peroral administrasjon. Kliniske forsøk ga et lignen-de bilde. the corresponding effect of compounds B and C with this form of administration was approx. 10 percent weaker than with oral administration. Clinical trials gave a similar picture.
Vannoppløseligheten av saltene av de ved fremgangsmåten ifølge oppfinnelsen oppnådde etere av salicylsyreamid hår den spesielle fordel at den åpner veien for an-vendelsesmuligheter, som er lukket for de kjente salicylsyreforbindelser som kan bru-kes som analgetiske, fordi disse er uopplø-selige i vann. The water solubility of the salts of the ethers of salicylic acid amide obtained by the method according to the invention has the particular advantage that it opens the way to possibilities of use, which are closed to the known salicylic acid compounds that can be used as analgesics, because these are insoluble in water.
