ABSTRACT:
The present invention relates to the preparation of new 1-(aminophenyl)-2-aminopropanone derivatives of the general formula: ##STR1## in which X is NH.sub.2, Y is H or a halogen atom, Z is H or a halogen atom, R.sub.1 is C.sub.1 -C.sub.4 alkyl or C.sub.3 -C.sub.6 cycloalkyl and R.sub.2 is H or C.sub.1 -C.sub.4 alkyl, or R.sub.1 and R.sub.2, taken together, can form, with the nitrogen atom to which they are bonded, a heterocyclic group selected from the group consisting of the pyrrolidino, morpholino, thiomorpholino, piperidino, hexamethyleneimino, piperazino, 4-methyl-piperazino, 4-(.beta.-hydroxyethyl)piperzaino, 4-phenylpiperazino and 4-(p-chlorophenyl)piperazino groups, and addition salts thereof.
These new derivatives are useful as pharmaceuticals. They are obtained by deacetylation of the corresponding acetylated products.
