Abstract
The invention discloses compounds formula (I) ##STR1## in which n represents the number 1 or 2, X represents a hydrogen atom or indicates that the phenyl ring to which it is attached is substituted by one or two substituents independently chosen from halogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy and hydroxyl, and R represents a hydrogen atom, a group of formula --CH.sub.2 --CO.sub.2 --R.sub.1 (in which R.sub.1 represents a hydrogen atom or a C.sub.1 -C.sub.6 alkyl group) or a group of formula --CH.sub.2 --CO--NR.sub.2 R.sub.3 (in which each of R.sub.2 and R.sub.3 is independently a hydrogen atom or a C.sub.1 -C.sub.3 alkyl group), or a pharmaceutically acceptable salt thereof, processes for their preparation and their use in the treatment of disorders of GABAergic transmission.
