   La présente invention est relative à la préparation de nouveaux dérivée d'imidazole possédant une chaîne latérale aminée, réponsdant à la formule générale suivante ! 
 EMI2.1 
 dans laquelle A représente une   Chaîne     aliphatique   ramifiée ou non contenant'de 1 à 6 atomes de carbone, R1 et R2   identiques   ou différents représentent   de l'hydrogène,   des .chaînes alipha- tiques ramifiées   ou   non, substituées ou non, des radicaux aryle, ou alkyl-aryle, ces substituants R1 et R2 pouvant faire partie d'un hétérocycle. 



   Leur groupe nitro peut être   attaché   en position 4 ou 
5 ; les isomères peuvent être séparés par cristallisation frac- tionnée. 



   Ces substances peuvent être préparées,, par exemple par réaction de sels de métaux, de préférence, les sels de sodium ou d'argent, de avec des substances répondant à la formule suivante ;

 étant particulièrement marquée sur lr "Trichomonas vaginalis". En outre, les substances de cette classe, telles que par exem- pie le N"6'-ethyl''!aorpholino-4(5)''Ritfo'-imidazole possèdent une bonne solubilité dans l'eau, solubilité qui est beaucoup plue élevée que celle que possède des produits similaires actifs

  "New imidazole derivatives and their preparation".

 <Desc / Clms Page number 2>

 



   The present invention relates to the preparation of novel imidazole derivative having an amino side chain, corresponding to the following general formula!
 EMI2.1
 in which A represents a branched or non-branched aliphatic chain containing from 1 to 6 carbon atoms, identical or different R1 and R2 represent hydrogen, branched or unsubstituted aliphatic chains, substituted or not, aryl radicals, or alkyl-aryl, these R1 and R2 substituents possibly forming part of a heterocycle.



   Their nitro group can be attached in position 4 or
5; isomers can be separated by fractional crystallization.



   These substances can be prepared, for example by reaction of metal salts, preferably the sodium or silver salts, with substances of the following formula;
 EMI2.2
 in which A, R1 and R2 have the aforementioned meanings, in dry solvents such as xylene, toluene, etc.

 <Desc / Clms Page number 3>

 



   Some of the compounds synthesized in this way exert considerable activity both "in vivo" and "in vitro" on many protozoan organisms, this activity
 EMI3.1
 being particularly marked on the "Trichomonas vaginalis". In addition, substances of this class, such as for example N "6'-ethyl"! Aorpholino-4 (5) "Ritfo'-imidazole have good solubility in water, which solubility is very high. higher than that of similar active products
 EMI3.2
 against IITriohononas vaginalis ", such as, for example, X-0-oxy..ethyl ... 2 ... methyl-S..nitro..imidl1zo1e.



  This further facilitates resorption of substances when "in vivo" administration is required, the compounds then declining to slow down thereby preventing the detrimental phenomenon of accumulation. The following examples illustrate the present invention without, however, limiting it.



   EXAMPLE 1.
 EMI3.3
 



  6 g of 4 (5) -n1troimideal sodium salt and 9 g of 0-ohloro-dthyl-morpholïne are reacted in 200 ml of dry toluene. The mixture is heated under reflux for 50 hours, then it is cooled and the solid residue is separated by filtration. The solvent is evaporated off under reduced pressure. The semi-solid product thus obtained solidifies on addition of petroleum ether and ethyl ether.
