1. A compound of Formula (I) or a pharmaceutically acceptable salt thereof; wherein: R1 is a (C1-C4)alkyl group which can optionally be substituted with a —(C1-C4)alkoxy or a RaNH group, Ra being selected from the group consisting of, (C1-C4)alkyl-C(═O)— and (C1-C4)alkyl-S(═O)2—; R2 is a hydrogen atom; R3 and R4 independently represent a (C1-C3)alkyl group; R5 is a hydrogen atom; R6 and R7 independently represent a hydrogen atom, a halogen atom, or R6 and R7 together with the carbon atom to which they are shown attached form a —C(═O)— group; R′ is —NH2 or —OR, wherein R is a hydrogen atom, a (C1-C3)alkyl group or a (C1-C3)alkyl-C(═O)— group Ar is an aryl or heteroaryl group which can optionally be substituted with one to four substituents independently selected from the group consisting of halogen, azido, hydroxy, (C1-C4)alkyl, (C1-C4)alkoxy, —O—(C1-C4)alkyl-(C1-C6)cycloalkyl, aryl, (C1-C4)alkyl-aryl-, (C1-C4)alkoxy-aryl-, amino-substituted aryl, N((C1-C4)alkyl)2-substituted aryl, aryloxy, heteroaryl, (C1-C4)alkyl-heteroaryl-, and RbRcN, or wherein two substituents at adjacent positions of the aryl or heteroaryl together with the atoms to which they are attached form a heterocyclic ring; and Rb and Rc are independently selected from the group consisting of hydrogen, (C1-C4)alkyl, halogeno(C1-C4)alkyl-, (C1-C4)alkoxy(C1-C4)alkyl-, aryl(C1-C4)alkyl- and acetylamino(C1-C4)alkyl-. |
