Les exemples suivants montrent comment  le procédé selon l'invention peut être mis en       oeuvre     <I>Exemple 1:</I>  On coule goutte à goutte 10 g     d'éthane-          sulfochlorure    dans une solution bien agitée de  10 g de     diéthylamino-3-amino-1-propane.    On  refroidit de façon à maintenir pendant l'addi  tion la température vers 10-20  C.

   Le     chlor-          hydrate    de     diéthylamino-3-éthanesulfamido-1-          propane    précipite. On l'extrait avec un mini  mum d'eau, ajoute la quantité nécessaire de  soude concentrée, épuise la base à l'éther,  sèche sur sulfate de soude, évapore le solvant  et distille sous pression réduite. On obtient  11 g d'une huile     Eb.o,3    =142  C.

   On fait. cou  ler goutte à goutte cette huile dans une sus  pension agitée de 2,5 g     d'amidure    de sodium  à     90        %        dans        60        em3        de        toluène        anhydre.        La          sodation    est exothermique, on la termine par  chauffage à 60  C pendant une heure. On  laisse refroidir, ajoute 8,2 g de     diéthylamino-          3-chloro-1-propane,    porte en l'espace d'une  heure à l'ébullition et maintient à l'ébullition  pendant 3 heures.

   On laisse refroidir, extrait  la solution     tolüénique    à l'acide sulfurique di  lué, précipite la base par     alcalinisation    à la  soude et l'extrait à l'éther. On sèche sur sul  fate de soude, évapore l'éther et distille. On  recueille 7,7 g de bis-     (diéthylamino-3-propyl-          1)-N,N-éthanesulfamide.        Eb.o,5    =169  C; P. P.  du     dipicrate    =148  C.  



       Exemple   <I>2:</I>  25 g     d'éthanesulfamide    de P. P. (capil  laire) = 57  C sont ajoutés, en agitant, à une  suspension de 10,5 g     d'amidure    de sodium à  90 % dans 250     em3    de toluène anhydre. On  chauffe 1 heure à 80  C. On refroidit à tem  pérature ordinaire et ajoute 36 g de     diéthyl-          amino-3-chloro-1-propane.    On chauffe 5 heures  à ébullition à reflux.

   On refroidit à tempé  rature ordinaire et ajoute 10,5 g     d'amidure     de sodium à     901/o.    On chauffe encore 1 heure  à 80  C, refroidit à température ordinaire,  ajoute 39 g de     diéthylamino-3-chloro-1-pro-          pane    et porte 5 heures à l'ébullition à reflux.    A     pr's        e        refroidisse        ment,        on        extrait   <B>à</B>     l'acide        sul-          furique        dilué    les produits basiques formés.

Après avoir chassé le sol  vant, il reste 82 g d'une huile jaune qui, par  fractionnement sous pression réduite, donne  50 g de bis-     (diéthyiamino-3-propyl-1)-N,N-          éthanesulfamide.  



  Process for preparing a new sulfonamide derivative. It has been found that the compounds corresponding to the following formula possess physiologically valuable properties, in particular for the treatment of states of traumatic shock and. hemorrhagic:

    
EMI0001.0004
    In this formula, R represents an alkyl radical containing less than 5 carbon atoms, or an aryl radical optionally substituted by a methyl residue or by a chlorine, an amino or acetylamino residue; A and Al are divergent hydrocarbon chains containing a maximum of 5 carbon atoms, which may be linear or branched, or aralkyl chains;

          R1 and R2 represent methyl or ethyl radicals, but (R1) #, and (R2) 2 can also form a chain comprising or not comprising a heteroatom (for example -N (R1) 2 or -N (R2) 2 may represent a residue (piperidine or morpholine). A and A1 as well as Ri and R2 may be the same or different.



  The present patent relates to a process for preparing .d'un .de. these new sulfonamide derivatives, bis- (diethylamino-3-propyl-1) - N, N-ethanesulfamide of formula
EMI0001.0025
    The process according to the invention is characterized in that one condenses a derivative of ethanesulfonic acid, of formula
EMI0001.0027
    with a substance of the formula
EMI0001.0028
    where X and Y are substituents removed during the condensation, with the exception of an -NH- group being in one of the two,

   in that the diethylamino-3-ethane-sulfamido-1-propane thus obtained is then coded by means of sodium amide and in that the sodium derivative is condensed with a halide of 3-di-ethylaminopropyl- (1 ).



  For the preparation of diethylamino-3-ethanesulfamido-1-propane which constitutes an intermediate product of the process, an ethanesulfohalide (X = halogen, such as chlorine, with diethylamino-3- -1-propane (Y = NH2), or you can <B> ï </B> amino condense sodium ethanesulfamide (X = NHNa) with diethyl-amino-3-halogeno-1-propane (Y ---- halogen, such as chlorinated ).



  Bis- (diethylamino-3-propyl-1) -N, N-ethanesulfamide is a new substance with interesting physiological properties; in particular, it has been shown to be very effective in the treatment of traumatic and hemorrhagic shock states. The following examples show how the process according to the invention can be carried out <I> Example 1: </I> 10 g of ethanesulfochloride are poured dropwise into a well-stirred solution of 10 g of 3-diethylamino -amino-1-propane. The mixture is cooled so as to maintain the temperature at around 10-20 C.

   Diethylamino-3-ethanesulfamido-1-propane hydrochloride precipitates. It is extracted with a minimum of water, the necessary quantity of concentrated sodium hydroxide is added, the base is exhausted with ether, dried over sodium sulphate, the solvent is evaporated off and the solvent is distilled off under reduced pressure. 11 g of an oil Eb.o, 3 = 142 C.

   We do. pour this oil dropwise into a stirred suspension of 2.5 g of 90% sodium amide in 60 em3 of anhydrous toluene. The sodation is exothermic, it is terminated by heating at 60 ° C. for one hour. Allowed to cool, added 8.2 g of diethylamino-3-chloro-1-propane, brought to the boil over the course of one hour and kept at the boil for 3 hours.

   Allowed to cool, the tolüene solution is extracted with dilute sulfuric acid, the base is precipitated by alkalinization with sodium hydroxide and the extract is extracted with ether. It is dried over sodium hydroxide, the ether is evaporated off and distilled. 7.7 g of bis- (diethylamino-3-propyl-1) -N, N-ethanesulfamide are collected. Eb.o, 5 = 169 C; P. P. of dipicrate = 148 C.



       Example <I> 2: </I> 25 g of PP ethanesulfamide (capillary) = 57 C are added, while stirring, to a suspension of 10.5 g of 90% sodium amide in 250 em3 of anhydrous toluene. The mixture is heated for 1 hour at 80 ° C. The mixture is cooled to room temperature and 36 g of diethyl-amino-3-chloro-1-propane are added. The mixture is heated for 5 hours under reflux.

   Cool to room temperature and add 10.5 g of sodium amide 901 / o. A further 1 hour is heated at 80 ° C., cooled to ordinary temperature, 39 g of diethylamino-3-chloro-1-propane are added and the mixture is brought to the boiling point under reflux for 5 hours. After cooling, the basic products formed are extracted <B> with </B> dilute sulfuric acid.

   By adding an excess of sodium hydroxide solution to these acid solutions, an oil settles which is extracted with ether. After having driven off the soil, 82 g of a yellow oil remain which, on fractionation under reduced pressure, gives 50 g of bis- (diethylamino-3-propyl-1) -N, N-ethanesulfamide.
