Patent ID: 8518998

Claim:
A method of treating pain, comprising: administering to a patient in need thereof, a pharmaceutically effective amount of a compound of the formula I, wherein A is phenylene which can be substituted by one or more identical or different substituents chosen from halogen, (C 1 -C 4 )-alkyl and trifluoromethyl; R 1 is chosen from R 7 R 8 N and Het; R 2 is phenyl or heteroaryl which can both be substituted by one or more identical or different substituents chosen from halogen, (C 1 -C 4 )-alkyl, trifluoromethyl, trifluoromethoxy, nitro, cyano, (C 1 -C 4 )-alkyl-O—, (C 1 -C 4 )-alkyl-CO—NH— and (C 1 -C 4 )-alkyl-S(O) 2 —; R 3 , R 4 , R 5 and R 6 , which are independent of each other and can be identical or different, are chosen from hydrogen, halogen, (C 1 -C 4 )-alkyl, trifluoromethyl, cyano and (C 1 -C 4 )-alkyl-O—; R 7 is chosen from hydrogen, (C 1 -C 4 )-alkyl and (C 3 -C 5 )-alkenyl; R 8 is chosen from (C 1 -C 4 )-alkyl, (C 1 -C 4 )-alkyl-O—(C 1 -C 4 )-alkyl-, di((C 1 -C 4 )-alkyl)N—(C 1 -C 4 )-alkyl-, (C 3 -C 5 )-alkenyl, (C 3 -C 7 )-cycloalkyl, (C 3 -C 7 )-cycloalkyl-(C 1 -C 4 )-alkyl-, phenyl-(C 1 -C 4 )-alkyl-, indanyl and pyridinyl-(C 1 -C 4 )-alkyl-, wherein cycloalkyl and pyridinyl can be substituted by one or more identical or different (C 1 -C 4 )-alkyl substituents; heteroaryl is a residue of a monocyclic 5-membered or 6-membered aromatic heterocycle which contains one or two identical or different ring heteroatoms chosen from nitrogen, oxygen and sulfur; Het is a residue of a monocyclic 5-membered, 6-membered or 7-membered saturated or partially unsaturated heterocycle which contains a ring nitrogen atom via which the group Het is bonded to the group -A-S(O) 2 —, and which can contain one further ring heteroatom chosen from nitrogen, oxygen and sulfur wherein the sulfur atom can carry one or two oxo groups, and which can be substituted by one or more identical or different (C 1 -C 4 )-alkyl substituents, and to which a benzene ring can be fused wherein the benzene ring can be substituted by one or more identical or different substituents chosen from halogen, (C 1 -C 4 )-alkyl and trifluoromethyl; in any of its stereoisomeric forms, or a mixture of stereoisomeric forms in any ratio, or a physiologically acceptable salt thereof.
