Claim:
A compound of the formula (I): in which R 2 represents an aryl group optionally substituted with one or more substituents chosen from halogen atoms, C 1-6 alkyl, C 1-6 alkyloxy, C 1-6 alkylthio, C 1-6 -fluoroalkyl, C 1-6 -fluoroalkyloxy and —CN; R 3 represents a hydrogen atom, C 1-3 alkyl, —NR 4 R 5 , hydroxyl or C 1-4 alkyloxy; A represents a group C 1-7 -alkylene optionally substituted with one or two groups R a ; B represents a group C 1-7 -alkylene optionally substituted with a group R b ; L represents either a nitrogen atom substituted with a group R c or R d , or a carbon atom substituted with a group R e1 and a group R d or two groups R e2 ; the carbon atoms of A and B being optionally substituted with one or more groups R f , which may be identical to or different than each other; R a , R b and R c are defined such that: two groups R a may together form a group C 1-6 -alkylene; R a and R b may together form a bond or a group C 1-6 -alkylene; R a and R c may together form a bond or a group C 1-6 -alkylene; R b and R c may together form a bond or a group C 1-6 -alkylene; R d represents a group chosen from a hydrogen atom and the groups C 1-6 -alkyl, C 3-7 -cycloalkyl, C 3-7 -cycloalkyl-C 1-6 -alkyl, C 1-6 -alkylthio-C 1-6 -alkyl, C 1-6 -alkyloxy-C 1-6 -alkyl, C 1-6 -fluoroalkyl, benzyl, C 1 -C 6 -alkyl-C(O) and hydroxy-C 1-6 -alkyl; R e1 represents a group —NR 4 R 5 or pyrrolidinyl or morpholinyl, optionally substituted by one or more substituents selected from fluoro, C 1-6 -alkyl, C 1-6 -alkoxy and hydroxyl; two groups R e2 form, with the carbon atom that bears them, pyrrolidinyl, piperidinyl or morpholinyl, optionally substituted by one or more substituents selected from R f ; R f represents a group C 1-6 -alkyl, C 3-7 -cycloalkyl, C 3-7 -cycloalkyl-C 1-6 -alkyl, C 1-6 -alkyloxy-C 1-6 -alkyl, hydroxy-C 1-6 -alkyl, C 1-6 -fluoroalkyl or benzyl; R 4 and R 5 represent, independently of each other, a hydrogen atom or a group C 1-4 alkyl, C 3-7 -cycloalkyl or C 3-7 -cycloalkyl-C 1-6 -alkyl; and R 7 and R 8 represent, independently of each other, a hydrogen atom or a group C 1-6 -alkyl; or a salt thereof.
