Zusammenfassung:The compounds correspond to the formula: in which R1 represents a hydrogen atom or a lower alkyl radical, R2 denotes an alkyl group containing from 3 to 10 carbon atoms, R3 represents a hydrogen or halogen atom and R4 represents a hydrogen or halogen atom or a nitro group. These compounds have sedative, anxiolytic and/or hypnotic properties; they can be used for the treatment of certain neuropsychic disorders. They are obtained from the corresponding methyl and ethyl esters (R2 = CH3, C2H5) according to three different processes.
