      Verfahren    zur Darstellung eines neuen therapeutisch wirksamen     Amidins.       Es     wurde    gefunden, dass man zu einem  neuen     therapeutisch    wirksamen     Amidin    ge  langen kann, wenn man einen     reaktionsfähi-          gen,    Ester d es     Oxyacet-ss-phenyläthylamidins     mit     Anilin,    umsetzt.     Gegebenenfalls    arbeitet  man in     GegenwaA        eines        Lösungsmittels.

      Process for the preparation of a new therapeutically effective amidine. It has been found that a new therapeutically effective amidine can be obtained if a reactive ester of oxyacet-ss-phenylethylamidine is reacted with aniline. If necessary, one works in the presence of a solvent.



       That so obtained phenylamineacet-ss-phenylethylamidine of the formula
EMI0001.0018
    forms a hydrochloride of P. 145-146 that it easily dissolves in water.



  The new compound should find therapeutic use.



  <I> Example: </I> 23.3 parts @ h @ oracet-ss-pheny @ ethy @ amidine hydrochloride and 21 parts aniline are heated to 100 for 1 hour. The reaction mixture is poured into water, mixed with sodium bicarbonate and extracted with ether.
