Patent ID: 7612076

Claim:
A compound of the formula I: wherein: R is hydrogen or lower alkyl; R 1 is selected from the group consisting of hydrogen, lower alkyl, C 3 -C 7 -alkenyl, C 3 -C 7 -alkinyl, lower halogenalkyl, lower hydroxyalkyl, lower alkoxyalkyl, C 3 -C 7 -cycloalkyl and lower C 3 -C 7 -cycloalkylalkyl; X is N and Y is C, or Y is N and X is C; m is 1; Z is SO 2 ; R 2 is selected from the group consisting of lower alkyl, C 3 -C 7 -alkenyl, C 3 -C 7 -alkinyl, lower halogenalkyl, lower hydroxyalkyl, lower alkoxyalkyl, C 3 -C 7 -cycloalkyl or C 3 -C 7 -cycloalkyl substituted by phenyl or lower alkyl, lower C 3 -C 7 -cycloalkylalkyl, unsubstituted phenyl or phenyl mono- or disubstituted by lower alkoxy or lower halogenalkyl, lower phenylalkyl wherein the phenyl ring is unsubstituted or mono- or disubstituted by lower alkyl, lower alkoxy, halogen or lower halogenalkyl, unsubstituted pyridyl or pyridyl mono- or disubstituted by lower alkoxy or halogen, and —NR 3 R 4 , R 3 is hydrogen or lower alkyl; R 4 is selected from the group consisting of lower alkyl, C 3 -C 7 -alkenyl, C 3 -C 7 -alkinyl, lower alkoxyalkyl, C 3 -C 7 -cycloalkyl, C 3 -C 7 -cycloalkyl substituted by phenyl, lower C 3 -C 7 -cycloalkylalkyl, unsubstituted phenyl or phenyl mono- or disubstituted by lower alkyl, lower alkoxy, halogen or lower halogenalkyl, or lower phenylalkyl wherein phenyl is unsubstituted or mono- or disubstituted by lower alkyl, lower alkoxy, halogen or lower halogenalkyl; or R 3 and R 4 together with the nitrogen atom to which they are attached form a 4-, 5-, 6- or 7-membered heterocyclic ring optionally containing a further heteroatom selected from nitrogen, oxygen or sulfur, said heterocyclic ring being unsubstituted or substituted by one, two or three groups independently selected from lower alkyl, lower alkoxy, oxo, halogen and halogenalkyl, or being condensed with a phenyl or cyclohexyl ring, said phenyl or cyclohexyl ring being unsubstituted or substituted by one, two or three groups independently selected from lower alkyl, lower alkoxy, halogen and halogenalkyl; and pharmaceutically acceptable salts thereof.
