The present invention relates to novel compounds of formula (IA) or a salt thereof: wherein: A is attached to the phenyl group at the meta position or the para position relative to the cyclopropyl group, and is selected from the group consisting of: —SO2NR5—, —SO2CR2R3—, —CR2R3SO2— and —NR5SO2—; R1 is hydrogen, C1-6alkyl, haloC1-6alkyl or C2-6alkylene; R2 and R3 are independently hydrogen or C1-6alkyl; R4 is hydrogen, halogen, C1-6alkyl, haloC1-6alkyl, C1-6alkoxy or haloC1-6alkoxy; R5 is hydrogen, C1-6alkyl, or a phenyl optionally substituted by R4; and R6 is hydrogen, C1-6alkyl, haloC1-6alkyl, C1-6alkoxy or haloC1-6alkoxy; processes for their preparation, intermediates used in these processes, pharmaceutical compositions containing them and their use in therapy, as modulators of dopamine D3 receptors, e.g. to treat substance related disorders, as antipsychotic agents premature ejaculation or cognition impairment.
