The present invention relates, by way of new industrial products, to 1-(acetylaminophenyl)-2-amino-propanone derivatives selected from the group consisting of (a) the compounds of the formula Ar--CO--CH(CH.sub.3)--NR.sub.1 R.sub.2 (I) in which R.sub.1 represents a C.sub.1 -C.sub.4 alkyl group or a C.sub.3 -C.sub.6 cycloalkyl group; R.sub.2 represents the hydrogen atom or a C.sub.1 -C.sub.4 alkyl group; R.sub.1 and R.sub.2, taken together, can form, with the nitrogen atom to which they are bonded, an N-heterocyclic group with 5 to 7 ring members, capable (i) of including a second heteroatom selected from N, O and S, and (ii) of being substituted, the said heterocyclic group NR.sub.1 R.sub.2 being selected from the group comprising pyrrolidino, morpholino, thiomorpholino, piperidino, hexamethyleneimino, piperazino, 4-methylpiperazino, 4-(.beta.-hydroxyethyl) piperazino, 4-phenylpiperazino and 4-(p-chlorophenyl)-piperazino groups; and Ar represents an acetylaminophenyl group of the formula ##STR1## in which X is CH.sub.3 CONH and Y and Z, which can be identical or different, each represent a hydrogen or halogen atom; and (b) their addition salts. These new products are useful as anti-depressants for the central nervous system. The invention also relates to the method for their preparation.
本发明涉及一种新的工业产品,即从下列化合物组中选择的1-(乙酰氨基苯基)-2-氨基丙酮衍生物:(a)式Ar-CO-CH(CH3)-NR1R2(I)中的化合物,其中R1代表C1-C4烷基或C3-C6环烷基;R2代表氢原子或C1-C4烷基;R1和R2一起与它们结合的氮原子可以形成5至7个环成员的N-杂环基团,能够包括从N、O和S中选择的第二个杂原子,并且能够被取代,所述杂环基团NR1R2被选择为包括吡咯烷基、吗啉基、硫代吗啉基、哌啶基、己亚甲基亚胺基、哌嗪基、4-甲基哌嗪基、4-(β-羟乙基)哌嗪基、4-苯基哌嗪基和4-(对氯苯基)-哌嗪基团的组;以及Ar代表公式中的乙酰氨基苯基:##STR1## 其中X为CH3CONH,Y和Z可以相同也可以不同,分别代表氢或卤素原子;以及(b)它们的加合物盐。这些新产品可用作中枢神经系统的抗抑郁剂。本发明还涉及它们的制备方法。
