Claim:
A compound of formula (I): wherein: R 1 is selected from the group consisting of (C 1 -C 6 )alkyl, (C 3 -C 7 )cycloalkyl, CH 2 COR 4 , phenyl and phenyl substituted with one or more substituents independently selected from hydroxy, halogen, or (C 1 -C 6 )alkyl; R 4 represents a hydroxyl, (C 1 -C 4 )alkoxy, amino, (C 1 -C 4 )alkylamino or di(C 1 -C 4 )alkylamino group; Ar 1 represents a radical selected from: R 5 represents a cyano, hydroxy(C 1 -C 4 )alkyl, (C 1 -C 6 )alkoxy(C 1 -C 4 )alkyl group or a (CH 2 ) n NR 7 R 8 , CO 2 R 7 , CONHNR 7 R 8 , CONR 7 R 8 , CONR 8 OR 9 , (CH 2 ) n NR 7 COR 8 or (CH 2 ) n NR 7 COOR 8 group; R 6 represents a hydrogen atom, a (C1-C4)alkyl group or one of the values given for R 5 ; or R 5 and R 6 are bonded together to form a 4- to 7-membered cycle comprising C atoms and 0 to 2 heteroatoms selected from N and O, said cycle optionally being substituted with one or more substituents independently selected from halogen, (C 1 -C 4 )alkyl, halogenated (C 1 -C 4 )alkyl, hydroxy(C 1 -C 4 )alkyl, (C 1 -C 4 )alkoxy(C 1 -C 4 )alkyl, (CH 2 ) m NR 7 R 8 , or a tert-butoxycarbonyl group; R 7 and R 8 each independently represent a substituent selected from H, phenyl, (C 1 -C 4 )alkyl, (C 1 -C 4 )alkyl-OH, (C 3 -C 7 )cycloalkyl, (C 3 -C 7 )cycloalkyl-NH 2 , (C 1 -C 4 )alkyl-(C 3 -C 7 )cycloalkyl, C(═NH)NH 2 , SO 2 (C 1 -C 6 )alkyl, and SO 2 -phenyl; R 8 may also represent a tert-butoxycarbonyl or benzyloxycarbonyl group; or R 7 and R 8 together with the nitrogen atom to which they are bonded constitute an azetidinyl, pyrrolidinyl, piperidinyl, piperazinyl or morpholinyl radical, said radical being unsubstituted or substituted one or more times with a (C 1 -C 6 )alkyl, (C 1 -C 4 )alkyl-OH, COO(C 1 -C 6 )alkyl or F group; R 9 represents a hydrogen atom or a (C 1 -C 4 )alkyl group; Ar 2 represents a phenyl group which is unsubstituted or substituted 1 to 5 times with substituents independently selected from a halogen atom or a (C 1 -C 4 )alkyl, trifluoromethyl or (C 1 -C 4 )alkoxy group; n represents 1, 2 or 3; m represents 0, 1, 2 or 3; or an acid addition salt thereof.
