Abstract: There are prepared compounds of the formula: ##SPC1## Wherein: n is an integer from 1 to 4; R.sub.1 is alkyl of 1 to 6 carbon atoms, a hydroxy group, an amino group, an alkoxy group having 1 to 6 carbon atoms, a phenyl group or a phenyl group substituted with alkyl of 1 to 6 carbon atoms, an alkoxy group of 1 to 6 carbon atoms, trifluoromethyl, fluorine or chlorine; A is oxygen, sulfur, the imino group, or an alkylimino group having 1 to 6 carbon atoms, or when R.sub.1 is phenyl or substituted phenyl A also is two alkoxy groups having 1 to 6 carbon atoms or alkylenedioxy with 2 to 4 carbon atoms or --C(R.sub.1)=A is the cyano group; B is oxygen, sulfur, an imino group or an alkylimino group having 1 to 6 carbon atoms; R.sub.2 is hydrogen, a hydroxy group, an alkyl group with 1 to 6 carbon atoms, an alkoxy group with 1 to 6 carbon atoms, or the group --O(CH.sub.2).sub.n -- C(=A)--R.sub.1 ; N.sub.o is nitrogen or an N-oxide group; and R.sub.3 and R.sub.4 are the same or different and are hydrogen, chlorine, fluorine, the trifluoromethyl group, alkyl groups of 1 to 6 carbon atoms or alkoxy groups with 1 to 6 carbon atoms, the tautomeric forms thereof and pharmaceutically acceptable salts thereof. The compounds have psychosedative, anxiolytic, spasmolytic and antipsychotic activity.
