Patent ID: 7462617

Claim:
A compound of formula wherein Ar is or unsubstituted or substituted 6-membered heteroaryl containing one, two or three nitrogen atoms, and wherein the substituted heteroaryl groups are substituted by one or more substituents selected from the group consisting of hydroxy, halogen, CN, (C 1 -C 6 )-alkyl, (C 1 -C 6 )-alkyl substituted by halogen, (C 1 -C 6 )-alkoxy, (C 1 -C 6 )-alkoxy substituted by halogen, NR 7 R 8 , C(O)R 9 and SO 2 R 10 ; R 1 is hydrogen or (C 1 -C 6 )-alkyl; R 2 is (C 1 -C 6 )-alkyl, (C 2 -C 6 )-alkenyl, wherein a hydrogen atom may be replaced by CN, C(O)—R 9 or (C 1 -C 6 )-alkyl, or is (C 2 -C 6 )-alkynyl, (C 1 -C 6 )-alkyl substituted by halogen, —(CH 2 ) n —(C 3 -C 7 )-cycloalkyl, —(CH 2 ) n -heterocycloalkyl, —C(O)—R 9 , —(CH 2 ) n -aryl or —(CH 2 ) n -5 or-6-membered heteroaryl containing one, two or three heteroatoms selected from the group consisting of oxygen, sulphur and nitrogen wherein aryl, cycloalkyl, heterocycloalkyl and heteroaryl are unsubstituted or substituted by one or more substituents selected from the group consisting of hydroxy, halogen, (C 1 -C 6 )-alkyl, (C 1 -C 6 )-alkyl substituted by halogen and (C 1 -C 6 )-alkoxy; R 3 , R 4 and R 6 are each independently hydrogen, hydroxy, halogen, (C 1 -C 6 )-alkyl or (C 1 -C 6 )-alkoxy; R 5 is CN, C(O)R 9 , SO 2 R 10 or NR 11 R 12 ; R 7 and R 8 are each independently hydrogen or (C 1 -C 6 )-alkyl; R 9 is (C 1 -C 6 )-alkyl, (C 3 -C 6 )-cycloalkyl, (C 1 -C 6 )-alkoxy or NR 7 R 8 ; R 10 is (C 1 -C 6 )-alkyl, (C 3 -C 6 )-cycloalkyl or NR 7 R 8 ; R 11 and R 12 are each independently hydrogen, or form together with the N-atom to which they are attached a 5-membered heteroaryl group; n is 0, 1 or 2; or a pharmaceutically acceptable acid addition salt thereof.
