Patent ID: 7612064

Claim:
A compound of formula (I) wherein R 1 represents C 5-10 aryl, C 5-10 aryl-C 1-4 alkyl, C 5-10 aryl-C 2-4 alkenyl or 5 or 6-membered heteroaryl containing 1, 2, 3, or 4 heteroatoms selected from at least one of nitrogen, sulfur, and oxygen, wherein the aryl and the heteroaryl may be substituted by one to five substituents independently selected from C 1-4 alkyl, halo-C 1-4 alkyl, C 1-4 alkoxy, di C 1-7 alkylamino, halogen, and nitro; and wherein two adjacent substituents together with atoms of the aryl or the heteroaryl may form a 5 membered heterocyclic ring containing at least one oxygen atom; R 2 is C 5-10 aryl or 5 or 6-membered heteroaryl containing 1, 2, 3, or 4 heteroatoms selected from at least one of nitrogen, sulfur, and oxygen, wherein the aryl or the heteroaryl may be substituted by one to five substituents independently selected from C 1-4 alkyl, C 1-4 alkoxy, and halogen; and wherein two adjacent substituents together with atoms of the aryl or the heteroaryl may form a 5 membered heterocyclic ring containing two oxygen atoms; R 3 represents a group CH 2 NR 6 R 7 ; R 6 represents hydrogen, C 1-7 alkyl, phenyl-C 1-4 alkyl optionally substituted by C 1-4 alkoxy, or amino-C 1-7 alkyl, wherein a nitrogen of the amino-C 1-7 alkyl can be substituted by up to two substituents selected from C 1-4 alkyl; C 5-10 aryl substituted by one substituent selected from 5 or 6-membered heteroaryl containing 1, 2, 3 or 4 heteroatoms selected from at least one of nitrogen, sulfur, and oxygen, heterocyclyl containing 4-10 atoms compromising 1, 2, or 3 heteroatoms selected from at least one of nitrogen, sulfur, and oxygen, and a sulfamoyl group SO 2 NR 4 R 5 , wherein said substituent on the aryl may be directly linked or linked via a spacer selected from C 1-4 alkylidene; and optionally one or two further substituents selected from C 1-4 alkyl; C 5-10 aryl substituted by cyano; or 5 or 6-membered heteroaryl containing 1, 2, 3 or 4 heteroatoms selected from at least one of nitrogen, sulfur, and oxygen; R 4 represents hydrogen; R 5 represents hydrogen; and R 7 represents hydrogen, C 1-4 alkyl, or C 1-4 alkylcarbonyl; or salts thereof.
