The present invention relates to novel compounds of formula (I) or a salt thereof: n n n n n n n n n n wherein:n G is a 5- or 6-membered heteroaromatic group, or is a 9- or 10-membered bicyclic heteroaromatic group containing one or two heteroatoms independently selected from nitrogen and oxygen, wherein G is not pyridyl, indazolyl or benzothiazolyl; p is an integer ranging from 0 to 4; R 1 is independently selected from a group consisting of: halogen, hydroxy, cyano, C 1-4 alkyl, haloC 1-4 alkyl, C 1-4 alkoxy, haloC 1-4 alkoxy, C 1-4 alkanoyl or SF 5 ; or corresponds to a group R 5 ; R 2 is hydrogen or C 1-4 alkyl; n is 2 or 3; X is S or —CH 2 —; R 3 is C 1-4 alkyl; R 4 is hydrogen, or a phenyl group, a heterocyclyl group, a 5- or 6-membered heteroaromatic group, or a 8- to 11-membered bicyclic group, any of which groups is optionally substituted by 1, 2, 3 or 4 substituents selected from the group consisting of: halogen, cyano, C 1-4 alkyl, haloC 1-4 alkyl, C 1-4 alkoxy and C 1-4 alkanoyl; R 5 is isoxazolyl, —CH 2 —N-pyrrolyl, 1,1-dioxido-2-isothiazolidinyl, thienyl, thiazolyl, pyridyl or 2-pyrrolidinonyl, wherein each group is optionally substituted by one or two substituents selected from: halogen, cyano, C 1-4 alkyl, haloC 1-4 alkyl, C 1-4 alkoxy and C 1-4 alkanoyl;n nprocesses for their preparation, intermediates used in these processes, pharmaceutical compositions containing them and their use in therapy, as modulators of dopamine D 3 receptors, e.g. to treat substance related disorders, as antipsychotic agents, premature ejaculation or cognition impairment. |
