Claim:
A compound of formula (I): wherein: R1 is a hydrogen atom, a linear or branched alkyl group, or an alkylalkoxy group; R2 is a hydrogen atom, a halogen atom, or a linear or branched alkyl group, â€”CF 3 , â€”OSO 2 CF 3 , â€”SO 2 CH 3 , â€”SO 2 NHCH 3 or â€”NHSO 2 CH 3 ; R3 is (i) a hydrogen atom; (ii) a linear or branched alkyl group; (iii) an alkylalkoxy group; (iv) an arylalkyl group or a heteroarylalkyl group, and the aryl or heteroaryl group is optionally substituted with one or two substituents, which are identical or different, selected from the group consisting of a halogen atom, an alkyl group containing 1-3 carbon atoms, an alkoxy group containing 1-3 carbon atoms, a hydroxyalkyl group containing 1-3 carbon atoms, â€”OH, â€”NRâ€²Râ€³, â€”NO 2 , â€”CF 3 , â€”CO 2 Râ€², Râ€²CON(Râ€³)â€”, Râ€²SO 2 N(Râ€³)â€”, and Râ€²Râ€³NSO 2 â€”, in which Râ€² and Râ€³, which are identical or different, are a hydrogen atom or an alkyl group containing 1-3 carbon atoms; (v) R iv R v NCO(CH 2 ) n â€”, in which n is an integer from 0 to 2, and R iv and R v , which are identical or different, are a hydrogen atom, an alkyl group containing 1-3 carbon atoms, an aryl group, or a heteroaryl group, optionally substituted with one or two substituents, which are identical or different, selected from the group consisting of a halogen atom, an alkyl group containing 1-3 carbon atoms, an alkoxy group containing 1-3 carbon atoms, a hydroxyalkyl group containing 1-3 carbon atoms, â€”OH, â€”NO 2 , â€”NH 2 , â€”CF 3 , â€”CO 2 H, â€”CO 2 â€”C 1-3 alkyl, â€”SO 2 NH 2 , and â€”NHSO 2 â€”C 1-3 alkyl; or (vi) C Î³ â€”(CH 2 ) m â€”, in which m is an integer from 0 to 2, and C Î³ is an alicyclic group containing 3 to 7 carbon atoms or a saturated 5- or 6-membered heterocyclic group containing at least one heteroatom selected from the group consisting of N and O, optionally N-substituted with an alkyl group containing 1 to 3 carbon atoms, or an acid-addition salt of the compound of formula (I) with a pharmaceutically acceptable organic or mineral acid, or a base-addition salt of the compound of formula (I) with a pharmaceutically acceptable organic or mineral base.
