The present invention relates to novel compounds of formula (I) or a salt thereof:
wherein
G is selected from a group consisting of: phenyl, a 5- or 6-membered monocyclic heteroaryl group, or a 8- to 11-membered heteroaryl bicyclic group;
p is an integer ranging from 0 to 5;
R1 is halogen, hydroxy, cyano, C1-4alkyl, haloC1-4alkyl, C1-4alkoxy, haloC1-4alkoxy, C1-4alkanoyl and SF5; or corresponds to a group R6; and when p is an integer ranging from 2 to 5, each R1 may be the same or different;
R2 is hydrogen or C1-4alkyl;
n is 3, 4, 5 or 6;
R6 is a moiety selected from the group consisting of: isoxazolyl, —CH2—N-pyrrolyl, 1,1-dioxido-2-isothiazolidinyl, thienyl, thiazolyl, pyridyl, 2-pyrrolidinonyl, and such R6 group is optionally substituted by one or two substituents selected from: halogen, cyano, C1-4alkyl, haloC1-4alkyl, C1-4alkoxy, C1-4alkanoyl;
R4 is selected in the group consisting of: hydrogen, halogen, hydroxy, cyano, C1-4alkyl, C3-7 cycloalkyl, haloC1-4alkyl, C1-4alkoxy, haloC1-4alkoxy, C1-4alkanoyl and NR′R″; or R4 is a phenyl group, a 5-14 membered heterocyclic group; and any of such phenyl or heterocyclic group is optionally substituted by 1, 2, 3 or 4 substituents selected from the group consisting of: halogen, cyano, C1-4alkyl, haloC1-4alkyl, C1-4alkoxy, C1-4alkanoyl, haloC1-4alkoxy and SF5;
R7 is hydrogen or C1-2alkyl;
R′ is H, C1-4 alkyl or C1-4 alkanoyl;
R″ is defined as R′;
R′ and R″ taken together with the interconnecting nitrogen atom may form a 5-, 6-membered saturated or unsaturated heterocyclic ring;
and their use in therapy, as modulators of dopamine D3 receptors.
