La présente invention a pour objet,à titre de produits indus- triels nouveaux, des dérivés de l'acide muoique. Elle concerne également un procédé de préparation de ces dérivés.
Ces nouveaux dérivés de l'acide mucique répondent à la formule 1 du dessin annexé, dans laquelle R désigne un reste hydrocarbure aliphatique de poids moléculaire peu élevé, R' désigne un atome d'hydrogène ou un reste hydrocarboné aliphatique de poids moléculaire peu élevé et Ac est une abréviation pour le reste acétylique CH3-CO-.
Or la demanderesse a trouvé que l'on peut obtenir ces composés d'une manière simple en faisant réagir en présence d'un agent fixant les acides une mole de dihalogénure de l'acide tétraacétylmucique répondant à la formule 2 du dessin annexé, dans laquelle Hal désigne un atome de chlore ou de brome, avec 2 moles d'amines répondant à la formule III du dessin annexé, dans laquelle R et R' ont les significations indiquées ci- dessus. Comme agent fixant les acides on peut utiliser par exemple un excès de l'amine qui doit réagir. La réaction peut être effectuée dans un diluant ou un solvant organique inerte approprié, par exemple dans du ben- zène, à chaud.
Comme amines répondant à la formule III entrent par exemple en

On peut obtenir le dichlorure de l'acide tétraacétylmucique à partir de l'acide tétraacétylmucique (Skraup, M. 14, 488) par exemple à l'aide de pentachlorure de phosphore (Diels, Löflund, Bo 47, 2352 (1914)) ou à l'aide de chlorure de thionyle (J. =lier B.47, 2655).
Les nouveaux dérivés de l'acide muoique conformes à l'invention accusent des propriétés pharmacologiques intéressantes. Ils présentent une forte activité antiphlogistique.
Les exemples suivants illustrent la préparation de ces nouveaux composés, sans toutefois limiter la portée de l'invention. Les parties sont comprises en poids sauf indications contraires.
Exemple 1.
On met en suspension 13,5 parties de dichlorure de l'acide té- traacétylmucique dans 200 parties en volume de benzène absolu et on ajoute goutte à goutte à cette suspension, en la refroidissant avec de l'eau, Il parties de diéthylamine dans 50 parties en volume de benzène absolu, à 30-350, en agitant. Lorsque l'addition est terminée, on fait refluer la solution pendant 2 heures. Après avoir refroidi le tout on l'additionne @ d'environ 100 parties en volume d'acide chlorhydrique 2n et on sépare par filtration la bis-diéthylamide de l'acide tétraacétylmuoique qui a préci- pité. On la lave encore avec une solution saturée aqueuse de bicarbonate de sodium et avec de l'eau.
Après une reoristallisation dans de l'acétate d'éthyle, elle présente un point de fusion à 194-1950.

Exemple 2.
On fait réagir comme indiqué ci-dessus 13,5 parties de dichlorure de l'acide tétraacétylmuoique dans 200 parties en volume de benzène absolu avec 18 parties de di-n-butylamine. Après refroidissement on lave dans un entonnoir à séparation la solution benzénique avec de l'acide chlorhydrique 2 n, une solution saturée de bicarbonate de sodium et de l'eau. Puis on sèche la solution sur du sulfate de sodium et on élimine le benzène par distillation. On recristallise le résidu dans de l'acétate d'éthyle ; son point de fusion est à 162-1630.
On peut obtenir de façon analogue par exemple les composés sui- vants, répondant à la formule 1.

The present invention relates, as new industrial products, to derivatives of muoic acid. It also relates to a process for preparing these derivatives.
These new mucic acid derivatives correspond to formula 1 of the appended drawing, in which R denotes an aliphatic hydrocarbon residue of low molecular weight, R 'denotes a hydrogen atom or an aliphatic hydrocarbon residue of low molecular weight and Ac is an abbreviation for the acetyl residue CH3-CO-.
Now, the Applicant has found that these compounds can be obtained in a simple manner by reacting in the presence of an acid-binding agent one mole of tetraacetylmucic acid dihalide corresponding to formula 2 of the appended drawing, in which Hal denotes a chlorine or bromine atom, with 2 moles of amines corresponding to formula III of the appended drawing, in which R and R 'have the meanings indicated above. As acid binding agent, it is possible, for example, to use an excess of the amine which is to be reacted. The reaction can be carried out in a suitable diluent or inert organic solvent, for example in benzene, while hot.
As amines corresponding to formula III enter, for example,

Tetraacetylmucic acid dichloride can be obtained from tetraacetylmucic acid (Skraup, M. 14, 488), for example using phosphorus pentachloride (Diels, Löflund, Bo 47, 2352 (1914)) or using thionyl chloride (J. = bind B.47, 2655).
The new muoic acid derivatives in accordance with the invention exhibit interesting pharmacological properties. They exhibit strong antiphlogistic activity.
The following examples illustrate the preparation of these new compounds, without however limiting the scope of the invention. Parts are included by weight unless otherwise indicated.
Example 1.
13.5 parts of tetraacetylmucic acid dichloride are suspended in 200 parts by volume of absolute benzene and added dropwise to this suspension, while cooling it with water, 11 parts of diethylamine in 50 parts. parts by volume of absolute benzene, at 30-350, with stirring. When the addition is complete, the solution is refluxed for 2 hours. After cooling the whole, it is added to about 100 parts by volume of 2n hydrochloric acid and the bis-diethylamide is filtered off from the precipitated tetraacetylmuoic acid. It is further washed with saturated aqueous sodium bicarbonate solution and with water.
After reoristallization in ethyl acetate, it exhibits a melting point of 194-1950.

Example 2.
13.5 parts of tetraacetylmuoic acid dichloride in 200 parts by volume of absolute benzene are reacted as indicated above with 18 parts of di-n-butylamine. After cooling, the benzene solution is washed in a separatory funnel with 2 n hydrochloric acid, saturated sodium bicarbonate solution and water. The solution is then dried over sodium sulfate and the benzene is removed by distillation. The residue is recrystallized from ethyl acetate; its melting point is at 162-1630.
