New heterocyclic compounds having the general formula wherein R is , , CO2R' or CONR'R'', wherein R' and R'' independently are C1-6-alkyl, C3-7-cycloalkyl or C1-6-alkoxymethyl; -A- is -C(=O)-NR'''-, -NR'''-C(=O)-, or , wherein R''' is C1-6-alkyl; X is C or N; and R4 is hydrogen, halogen, CN, C1-6-alkyl, C1-6-alkynyl, trimethylsilyl-C1-6-alkynyl, aryloxy which may be substituted with halogen, aralkoxy, C3-7-cycloalkoxy which may be substituted with one or more C1-6-alkyl groups,or NR''''R''''', wherein R'''' and R''''' independently are C1-6-alkyl or together with the nitrogen atom form a 3-7 membered heterocyclic ring. The compounds are useful in psychopharmaceutical preparations as anticonvulsants, anxiolytics, hypnotics, and nootropics. |
