Claim:
A compound of formula (I): wherein: X represents a phenyl group optionally substituted with one or more groups chosen, independently of each other, from the following atoms or groups: halogen, (C 1 -C 6 )alkoxy, (C 1 -C 6 )alkyl, NRaRb, cyano, and (C 1 -C 6 )alkoxycarbonyl, the groups (C 1 -C 6 )alkyl and (C 1 -C 6 )alkoxy being optionally substituted with one or more halogen atoms; R 1 represents a hydrogen atom, a halogen, a group (C 1 -C 6 )alkoxy, a group (C 1 -C 6 )alkyl or a group NRaRb; the alkyl and alkoxy groups possibly being substituted with one or more halogen, hydroxyl, amino, or a group (C 1 -C 6 )alkoxy; R 2 represents an unsaturated, partially saturated or totally saturated aromatic heterocyclic group, optionally substituted with one or more groups chosen, independently of each other, from the following atoms or groups: hydroxyl, (C 1 -C 6 )alkoxy, halogen, cyano, NRaRb, —CO—R 5 , —CO—NR 6 R 7 , —CO—O—R 8 , —NR 9 —CO—R 10 (C 3 -C 7 )cycloalkyl(C 1 -C 6 )alkyl, (C 3 -C 7 )cycloalkyl(C 1 -C 6 )alkoxy, a group (C 1 -C 6 )alkyl, optionally substituted with one or more hydroxyl or NRaRb, an oxido group, whereby R 2 is linked to the imidazo[1,2-a]pyridine moiety of formula (I) via a carbon-carbon bond; R 3 represents a hydrogen atom, a group (C 1 -C 6 )alkyl, a group (C 1 -C 6 )alkoxy or a halogen atom; R 4 represents a hydrogen atom, a group (C 1 -C 4 )alkyl, a group (C 1 -C 4 )alkoxy or a fluorine atom; R 5 represents a hydrogen atom, a phenyl group or a group (C 1 -C 6 )alkyl; R 6 and R 7 , which may be identical or different, represent a hydrogen atom or a group (C 1 -C 6 )alkyl or form, with the nitrogen atom, a 4- to 7-membered ring optionally including another heteroatom chosen from N, O and S; R 8 represents a group (C 1 -C 6 )alkyl; R 9 and R 10 , which may be identical or different, represent a hydrogen atom or a group (C 1 -C 6 )alkyl; Ra and Rb are, independently of each other, hydrogen or (C 1 -C 6 )alkyl or form, with the nitrogen atom that bears them, a 4- to 7-membered ring, optionally including another heteroatom chosen from N, O and S; or an acid addition salt thereof; with the exception of N-(4-bromophenyl)-6-(1-methyl-2-piperidinyl)imidazo[1,2-a]pyridine-2-carboxamide.
