Claim:
A compound having the formula or N-oxide, salt, stereoisomeric form, or ester thereof wherein R 1 and R 2 are, each independently, hydrogen, Het 1 , Het 2 or Y or R 1 and R 2 generate a ring, said ring is 3 to 7 membered and may be saturated or unsaturated wherein the ring members are optionally substituted by hydroxy, wherein Y is —C (═O)—C 1-6 alkyl-Het 1 or —C(═O)—C 1-6 alkyl-Het 2 or —C(═O)—C 1-6 alkyl-amino-C 1 -C 6 alkyl optionally substituted by Het 1 or Het 2 , Het 1 as a group or part of a group is defined as a saturated or partially unsaturated monocyclic, bicyclic or tricyclic heterocycle which contains one or more heteroatom ring members selected from nitrogen, oxygen or sulphur and which is optionally substituted on one or more carbon nitrogen atoms by C 1-6 alkyl, C 1-6 alkyloxy, aminoC 1-6 alkyl, C 1-6 alkyl-oxy-C 1-6 alkyl, benzyl, halogen, hydroxy, oxo, optionally mono- or disubstituted amino, optionally mono- or disubstituted aminoalkyl, nitro, acetyl, cyano, haloC 1-6 alkyl, carboxyl, C 1-6 alkoxycarbonyl, C 1-6 alkyl-Het 2 , C 3-7 cycloalkyl, optionally mono- or disubstituted aminocarbonyl, methylthio, methylsulfonyl, aryl or a saturated or partially unsaturated monocyclic, bicyclic or tricyclic cycle or heterocycle having 3 to 14 ring members; and wherein Het 2 as a group or part of a group is defined as an aromatic monocyclic, bicyclic or tricyclic heterocycle which contains one or more heteroatom ring members selected from nitrogen, oxygen or sulphur and which is optionally substituted on one or more carbon atoms by C 1-6 alkyl, C 1-6 alkyloxy, aminoC 1-6 alkyl, halogen, hydroxy, optionally mono- or disubstituted amino, nitro, cyano, haloC 1-6 alkyl, carboxyl, C 1-6 alkoxycarbonyl, C 3-7 cycloalkyl, optionally mono- or disubstituted aminocarbonyl, methylthio, methylsulfonyl, aryl, Het 1 or an aromatic monocyclic, bicyclic or tricyclic cycle or heterocycle having 3 to 12 ring members.
