  Process for the preparation of new iminodibenzyl derivatives
The invention relates to a process for the preparation of new N -heterocyclic compounds with valuable pharmacological properties.



   Iminodibenzyl derivatives substituted in a benzene ring by a disubstituted sulfamoyl radical have not yet become known. It has now been found that such compounds of the general formula I

 EMI1.2
 
 EMI1.3
 
 EMI1.4
 

 <Desc / Clms Page number 2>

 
 EMI2.1
 oneIn the compounds of general formula I, Rt and R are embodied, for example, by methyl, ethyl, n-propyl or n-butyl radicals or, together with the adjacent nitrogen atom, form e.g. B. the 1-pyrrolidinyl, piperidino or 4-morpholine radical. Z is, for example, an ethylene, propylene,
 EMI2.2
 methyl, ss- (1-methyl-2-piperidinyl) -ethyl, 1-methyl-3-piperidinylmethyl or 1-methyl-4-piperidinyl radical.



   To prepare new compounds of general formula I, a compound of general formula II is heated
 EMI2.3
 in which R, IL, Z and Am have the meaning given above, up to the elimination of 1 mol of carbon dioxide.



   The compounds of general formula II are in turn z. B. by allowing phosgene to act on 3-sulfamoyl-iminodibenzyls with a disubstituted sulfamoyl group and reacting the resulting disubstituted 3-sulfamoyl-5-chlorocarbonyl-iminodibenzyls with amino alcohols of the general formula III
 EMI2.4
 in which Am and Z have the meanings given above.

   With inorganic or organic acids, such as hydrochloric acid, hydrobromic acid,
Sulfuric acid, phosphoric acid, methanesulfonic acid, ethanedisulfonic acid, ss-hydroxyethanesulfonic acid,
Acetic acid, succinic acid, fumaric acid, maleic acid, malic acid, tartaric acid, citric acid, benzoic acid, salicylic acid and mandelic acid form the tertiary base salts, some of which are water-soluble.



   The following example is intended to explain the production of the new compounds in more detail. Parts mean parts by weight; these relate to parts of volume as grams to cubic centimeters. The
Temperatures are given in degrees Celsius.

 Fractions are converted into the hydrochlorides, from which 3-dimethylsulfamoyl-5- (γ-dimethyl-aminopropyl) -iminodibenzyl hydrochloride with a melting point of 186-1880 is obtained by recrystallization from ethanol.



   In a manner analogous to that described in the preceding examples, the
