Opening claim text (preview).
The invention claimed is: 1. A compound of formula (I), the N-oxide forms, the pharmaceutically acceptable addition salts and the stereo-chemically isomeric forms thereof, wherein the dotted lines represent optional bonds; X is >N—; is —N—C(O)— or —N═CR 4 —, wherein R 4 is hydroxy; L is a direct bond or a bivalent radical selected from —C(O)—, —C(O)—NH—, —NH—, —C(O)—C 1-6 alkanediyl-, —C(O)—O—C 1-6 alkanediyl- or —C 1-6 alkanediyl-; R 1 is hydrogen, halo, C 1-6 alkyloxy or C 1-6 alkyl; R 2 is hydrogen, hydroxy, C 1-6 alkyloxy or aminocarbonyl; R 3 is hydrogen, or C 1-6 alkyloxy; Z is amino, cyano or a radical selected from wherein each R 5 and R 6 is independently selected from hydrogen, halo, amino, C 1-6 alkyl, or C 1-5 alkyloxy. 2. A pharmaceutical composition comprising pharmaceutically acceptable carriers and as an active ingredient a therapeutically effective amount of a compound as claimed in claim 1 . 3. A process of preparing a pharmaceutical composition as claimed in claim 2 wherein the pharmaceutically acceptable carriers and a compound as claimed in claim 1 are intimately mixed. 4. A combination of a compound with a chemotherapeutic agent wherein said compound is a compound of formula (I) the N-oxide forms, the pharmaceutically acceptable addition salts and the stereo-chemically isomeric forms thereof, wherein the dotted lines represent optional bonds; X is >N—; is —N—C(O)— or —N═CR 4 —, wherein R 4 is hydroxy; L is a direct bond or a bivalent radical selected from —C(O)—, —C(O)—NH—, —NH—, —C(O)—C 1-6 alkanediyl-, —C(O)—O—C 1-6 alkanediyl- or —C 1-6 alkanediyl-; R 1 is hydrogen, halo, C 1-6 alkyloxy or C 1-6 alkyl; R 2 is hydrogen, hydroxy, C 1-6 alkyloxy or aminocarbonyl; R 3 is hydrogen, or C 1-6 alkyloxy; Z is amino, cyano or a radical selected from wherein each R 5 and R 6 is independently selected from hydrogen, halo, amino, C 1-6 alkyl, or C 1-5 alkyloxy. 5. A process for preparing a compound as claimed in claim 1 , characterized by reacting an intermediate of formula (II) with an intermediate of formula (III), wherein W is an appropriate leaving group, with the formation of a compound of formula (I-a), wherein L 1 is —C 1-6 alkanediyl-NH— and both dotted lines can be a bond, in a reaction-inert solvent and with the addition of an appropriate base, 6. A compound having the formula the N-oxide forms, the pharmaceutically acceptable addition salts and the stereo-chemically isomeric forms thereof. 7. A pharmaceutical composition comprising pharmaceutically acceptable carriers and as an active ingredient a therapeutically effective amount of a compound as claimed in claim 6 .
