摘要

Compounds ofthe formula:- <CHEM> wherein R<1> and R<2>, which may be the same or different, stand for hydrogen, a halogen atom or a nitro group, or a halogenoalkyl, alkyl, alkoxy or alkylthio radical of not more than 6 carbon atoms, and R<3> stands for hydrogen, fluorine, chlorine, bromine or methoxy, or a halogenoalkyl or alkyl radical of not more than 6 carbon atoms, provided that R<1>, R<2> and R<3> do not all stand for hydrogen at the same time, and R<4> stands for hydrogen or an alkanoyl radical of not more than 6 carbon atoms. Three processes for the manufacture of said compounds. Pharmaceutical compositions comprising one of said compounds and a pharmaceutical diluent or carrier. The compounds exhibit anticonvulsant, anti-anxiety and antipsychotic activity.
