Patent ID: 8791100

Claim:
A compound of formula (I) or a pharmaceutically acceptable salt thereof; wherein, R1 is hydrogen, halogen or C 1 -C 6 alkyl optionally substituted by halogen; R2 is halogen, C 1 -C 6 alkyl optionally substituted by halogen, cyano, or C 1 -C 6 alkoxy optionally substituted by halogen; or R1 and R2 together with the C-atoms to which they are attached form an aryl ring with 6-10 carbon atoms, which may optionally be substituted by 1-4 substituents selected from cyano, C 1 -C 4 -alkyl optionally substituted by halogen, C 1 -C 4 -alkoxy optionally substituted by halogen, and halogen; R3 is hydrogen, halogen or C 1 -C 6 alkyl optionally substituted by halogen; R4 is hydrogen, C 3 -C 6 cycloalkyl or C 1 -C 6 alkyl optionally substituted by halogen; R5 is hydrogen or C 1 -C 6 alkyl; R6 and R7 are independently selected from H and C 1 -C 6 alkyl or they may form together with the carbon atom to which they are attached a 3-7 membered saturated carbocyclic ring; R8 and R9 are independently selected from H and C 1 -C 6 alkyl, or R8 and R9 may form together with the atoms to which they are attached a 4-7 membered heterocyclic ring, optionally substituted one or more times by C 1 -C 6 -alkyl optionally substituted by halogen, trifluoromethyl, hydroxy, or amino; n=1, 2, 3 or 4; R10 is hydrogen, C 1 -C 6 alkyl, amino, hydroxy or C 1 -C 6 alkoxy; R is selected from H; phenyl being optionally substituted by C 1 -C 6 alkyl, C 1 -C 6 alkoxy, halogen or hydroxy; and C 1 -C 6 alkyl optionally substituted by C 1 -C 6 alkoxy, halogen, hydroxy, or phenyl optionally substituted by C 1 -C 6 alkyl, C 1 -C 6 alkoxy, halogen or hydroxy, X 1 , X 2 , X 3 and X 4 , are each independently selected from N or CR11, R11 in each case being independently selected from H, halo, cyano, C 1 -C 6 alkoxy, C 1 -C 6 alkyl optionally substituted by halo, or —SO 2 —C 1 -C 6 alkyl; and Y stands in each occurrence independently for CR12R13 wherein R12 and R13 are independently selected from H and C 1 -C 6 alkyl.
