Compounds of general formula I STR1 wherein: X represents oxygen or sulphur; each of R1 and R3 independently represents hydrogen or a C1 -C4 alkyl group; Ar represents: a phenyl ring optionally substituted by one, two or three C1 -C4 alkoxy groups and/or by one or two halogen atoms; a phenyl ring of the general formula STR2 wherein R2 represents halogen, 4,5-benzo, C1 -C8 alkoxy, C1 -C4 alkylcarbonyl or Am, wherein Am represents amino, methylamino or dimethylamino, R4 represents C1 -C8 alkyl, n is 1 or 2; or a pyrimidinyl moiety of the general formula STR3 wherein R5 is C1 -C4 alkyl; and their N-oxides and pharmaceutically acceptable salts are useful as anxiolytic agents. A preferred compound is R-(+)-4-amino-N-(1-azabicyclo[2.2.2]oct-3-yl)-5-chloro-2-methoxybenzamide.

Enantiomer of absolute configuration S of formula: STR1 where: X=O or S; and Ar denotes a: * phenyl ring substituted with one, two or three C1 -C4 alkoxy groups; * phenyl ring substituted at the 2-position with a OCH3 group and at the 5-position with a halogen atom or a lower alkylcarbonyl group; * phenyl ring substituted at the 2-position with OCH3, at the 4-position with NH2 or alkylcarbonyl-NH and at the 5-position with a halogen; * 3-fluoro-2-methoxyphenyl group; * 5-pyrimidinyl group substituted at the 2-position with NH2 and in the 4-position with alkoxy or phenyloxy. These compounds are useful as medicinal products having activity in respect of gastric movements and antiemetic activity.
