Patent ID: 6949583

Claim:
Benzofuran derivatives of general formula: and their pharmaceutically acceptable salts, in which formula: A represents a linear or branched C 1 -C 5 alkylene group optionally substituted by a hydroxyl group or A represents a group of general formula: —R 19 —O—R 20 — (h) in which R 19 and R 20 , which are identical or different, each represent a linear or branched C 1 -C 4 alkylene group, R 30 and R 31 , taken together, represent a carbonyl group with the carbon to which they are attached or represent a group of general formula: —O—R 29 —O— (m) in which R 29 represents a C 1 -C 4 alkylene group, T represents hydrogen or a C 1 -C 4 alkyl radical, R represents: the cyano, hydroxymethyl, formyl or tetrazolyl group, or an ester group of general formula: in which R 4 represents a linear or branched C 1 -C 6 alkyl group or a C 3 -C 6 cycloalkyl group, R 1 represents hydrogen, a linear or branched C 1 -C 6 alkyl group, a C 3 -C 6 cycloalkyl group, a benzyl group or a phenyl group optionally substituted by one or more substituents selected from halogen atoms, C 1 -C 4 alkyl groups or C 1 -C 4 alkoxy groups or R 1 represents a group of general formula: in which R 21 represents a linear or branched C 1 -C 4 alkylene group and R 22 represents a linear or branched C 1 -C 4 alkyl group or R 1 represents a group of general formula: —R 23 —OH (j) in which R 23 represents a linear or branched C 1 -C 6 alkylene group, R 2 and R 3 , which are identical or different, represent hydrogen, a linear or branched C 1 -C 6 alkyl group optionally substituted by one or more halogen atoms or by a pyrrolidinyl group, a C 3 -C 6 cycloalkyl group or a group of general formula: —R 24 —O—R 25 (k) in which R 24 represents a linear or branched C 1 -C 4 alkylene group and R 25 represents a linear or branched C 1 -C 4 alkyl group, or R 2 and R 3 , when they are taken together, represent a linear or branched C 3 -C 10 alkylene group W, W′ and Z are such that: when W and W′, which are identical, represent CH, Z represents —O— or —S—, when W represents CH and W′ represents C—R 13 , Z represents R 13 and R 14 being identical or different and representing hydrogen, a halogen atom, a C 1 -C 4 alkyl radical or a C 1 -C 4 alkoxy radical, X represents —O—, these benzofuran derivatives being in the form of individual isomers or of mixtures of the latter.
