Abstract
Process for obtaining aminopropane derivatives being characterized because the nitrile-butyl acids which in the α they are substituted by a substituted phenyl radical in the γ position by the group ** (see formula) ** where r4 and r6 form low molecularized alkyl residues together with ** (see formula) ** the rest of a heterocyclic ring and that in the β and/or γ they can still carry low-molecular alkyl residues with a maximum of 5 carbon atoms reacted in the presence of acid-combining agents with 8-halogen-caffeine and in the obtained compounds the cyan group is replaced by hydrogen.
