Patent ID: 8124621

Claim:
A compound of formula I wherein: R1, R2, R3 and R4 are independently selected from the group consisting of hydrogen, F, Cl, Br, I, CN, NO 2 , CF 3 , CH 3 —SO 2 , alkyl having 1, 2, 3 or 4 carbon (C) atoms, NH 2 , NH—CH 3 and N(CH 3 ) 2 ; R5 and R6 are independently selected from the group consisting of hydrogen, alkyl having 1, 2, 3, 4, 5 or 6 C atoms, CF 3 —CH 2 —, cycloalkyl having 3, 4, 5 or 6 C atoms and cyclopropyl-CH 2 —, or R5 and R6, together with the nitrogen atom to which they are bonded form a 4-, 5-, 6-, 7-, 8-, 9- or 10-membered ring in which one or two CH 2 groups may be replaced independently of one another by NR12, sulfur, oxygen, C(O) or SO 2 ; R12 is a hydrogen, alkyl having 1, 2, 3 or 4 C atoms or cycloalkyl having 3, 4, 5 or 6 C atoms; R7 is a hydrogen or alkyl group having 1, 2, 3 or 4 C atoms; R8 and R9 are independently selected from the group consisting of hydrogen, F, Cl, Br, OH, an alkyl group having 1, 2, 3 or 4 C atoms, CH 3 O, CF 3 , and CH 3 SO 2 ; R10 and 11 are R13-(C m H 2m )—B n , where m zero, 1, 2, 3 or 4; n zero or 1; B —CO—, —CONR14- or —SO 2 —; and R14 is a hydrogen or an alkyl group having 1, 2, 3, 4, 5 or 6 C atoms; R13 is selected from the group consisting of hydrogen, alkyl having 1, 2, 3 or 4 C atoms, cycloalkyl having 3, 4, 5 or 6 C atoms, 1-pyrrolidinyl, 1-piperidinyl, 1-(4-methylpiperazinyl), 1-morpholinyl, —COOR15, OR16, NR17R18 and phenyl each of which have at least one additional substituent selected from the group consisting of chlorine, fluorine, methyl and methoxy; R15, R16, R17 and R18 are hydrogen or alkyl having 1, 2, 3, 4, 5 or 6 C atoms; or R10 and R11, together with the nitrogen atom to which they are bonded, form a 4-, 5-, 6-, 7-, 8-, 9- or 10-membered ring in which one, two, three or four CH 2 groups may be replaced independently of one another by NR19, sulfur, oxygen, C(O) or SO 2 ; R19 is hydrogen, alkyl having 1, 2, 3 or 4 C atoms or cycloalkyl having 3, 4, 5 or 6 C atoms; or a pharmaceutically acceptable salt or trifluoroacetate thereof.
