Abstract
The present invention is directed to compounds of formula (I): where X, Y, R1, R2 and R3 are defined therein, which can act as modulators of viral replication and/or virus production, especially of the hepatitis C virus (HCV).

- where R11 and R12 are each independently hydrogen or C1-6alkyl;
- and
- R15′ is CN, CF3, C2-4alkenyl, phenyl, OBn, C(O)C1-4alkyl, or C(O)phenyl.
A method of treating HCV infection by administering an effective amount of a compound of formula (I) or a pharmaceutically acceptable salt thereof:
- wherein
- X and Y are independently N;
- R1 is C(O)OR4, C(O)NR5R6, or C(O)R7;
- R2 is C(O)NR9R10 or NR9C(O)R10;
- R3 is absent or selected from halogen, hydroxy, C1-6alkyl and C1-6alkoxy;
- R5 and R9 are each independently hydrogen, C1-6alkyl or C3-8cycloalkyl;
- R4, R6, R7 and R8 are each independently selected from C1-6alkyl, C2-6alkenyl, C2-6alkynyl, (CH2)0-3C3-8cycloalkyl, C1-6alkoxy, (CH2)0-3aryl, (CH)2aryl, (CH2)0-3Oaryl, (CH2)0-3heteroaryl and (CH2)0-3Oheteroaryl, optionally substituted by hydroxy, halogen, CN, CF3, C1-4alkyl, C1-4alkoxy, (CH2)0-3NR11C(O)OR12, (CH2)0-3aryl or (CH2)0-3heteroaryl,
- where R11 and R12 are each independently hydrogen or C1-6alkyl;
- R10 is (CH2)0-3aryl or (CH2)0-3heteroaryl, optionally substituted by halogen, CN, CF3, C1-4alkyl, C2-4alkenyl, OR13, C(O)R13, C(O)OR13, aryl, (CH)2aryl, (CH)2C(O)OR13 or NR13R14,
- where R13 and R14 are each independently hydrogen, C1-4alkyl or (CH2)0-3aryl,
- and where the optional substituent is further optionally substituted by hydroxy or halogen,
- and R10 may further be fused to a 5 - or 6-membered ring, which ring may be partially or fully unsaturated and which ring may contain one or two N atoms, said ring being optionally substituted by hydroxy, halogen, C1-4alkyl, C1-4alkoxy, C(O)R15 and C(O)OR15,
- where R15 is C1-4alkyl or aryl;
- with the proviso that the compound of formula (I) is not:
- tert-butyl4-(4-{[(4-hydroxyphenyl)amino]carbonyl}phenyl)piperazine-1-carboxylate,
- tert-butyl4-(4-{[(4-bromophenyl)amino]carbonyl}phenyl)piperazine-1-carboxylate,
