Claim:
A compound according to formula I, wherein A 1 , A 2 and A 3 are each individually selected from N and CH, provided that at least one of A 1 , A 2 or A 3 is N and at least one of A 1 , A 2 or A 3 is CH; R 1 is selected from the group consisting of lower alkyl, cycloalkyl, lower cycloalkylalkyl, lower hydroxyalkyl, lower alkoxyalkyl, lower halogenalkyl, lower carbamoylalkyl, lower alkylcarbonylaminoalkyl, lower phenylalkyl, lower heterocyclylalkyl wherein the heterocyclyl group is unsubstituted or substituted by oxo, lower heteroarylalkyl wherein the heteroaryl group is unsubstituted or mono- or di-substituted by lower alkyl, and phenyl which is unsubstituted or mono- or di-substituted by halogen; R 2 and R 6 independently from each other are hydrogen or halogen; R 3 and R 5 independently from each other are selected from the group consisting of hydrogen, lower alkyl, lower alkoxy, halogen, lower halogenalkyl, lower halogenalkoxy and cyano; R 4 is selected from the group consisting of hydrogen, lower alkoxy, halogen, lower halogenalkyl, lower halogenalkoxy and cyano; R 7 and R 8 together with the C atoms to which they are attached form a cycloalkyl ring, or R 7 is hydrogen and R 8 is lower halogenalkyl or cycloalkyl; and R 9 is selected from the group consisting of hydrogen, lower alkyl, lower halogenalkyl, lower alkoxyalkyl and lower carbamoylalkyl; or a pharmaceutically acceptable salt thereof.
