  • Publication number: 20080096869
    Abstract: the N-oxide forms, the pharmaceutically acceptable addition salts and the stereochemically isomeric forms thereof, wherein n represents an integer being 1 or 2; R1 and R2 each independently represents hydrogen C1-4alkyl, NR9R10, C1-4alkyloxy; or R1 and R2 taken together with the carbon atom with which they are attached form a C3-6cycloalkyl; and where n is 2, either R1 or R2 may be absent to form an unsaturated bond; R3 represents a C6-12cycloalkyl, preferably selected from cylo-octanyl and cyclohexyl or R3 represents a monovalent radical having one of the following formulae ?wherein said C6-12cycloalkyl or monovalent radical may optionally be substituted with one, or where possible two, three or more substituents selected from the group consisting of C1-4alkyl, C1-4alkyloxy, halo or hydroxy; Q represents Het1 or Ar2 wherein said C3-8cycloalkyl, Het1 or Ar2 are optionally substituted with one or where possible two or more substituents selected from halo, C1-4alkyl, C1-4alkyloxy, hydroxy, nitro, NR5R6
