Abstract
The invention relates to compounds of the formula (I), to the preparation and use thereof for the preparation of a medicament for the treatment of diseases, in particular tumours and/or diseases in the development or course of which kinases are involved.
Claims18
Compounds of the formula I
- in which
- R1 denotes H, A, Ar, Ar-A or A-Ar,
- A denotes unbranched, branched or cyclic alkyl having 1-14 C atoms, in which one or two CH2 groups may be replaced by an O or S atom and/or by an NH, NA, CONH, NHCO or —CH═CH— group and/or, in addition, 1-7 H atoms may be replaced by HaI, and in which one or two CH3 groups may be replaced by NH2, NAH, NA2, NHCOOA, NHCONHA, NHCONHAr, or CN,
- Ar denotes a mono- or bicyclic aromatic homo- or heterocycle having 1 to 4 N, O and/or S atoms and 5 to 10 skeleton atoms, which may be unsubstituted or mono-, di- or trisubstituted by carbonyl oxygen, HaI, A, OH, OA, NH2, NHA, NA2, NO2, CN, OCN, SCN, COOH, COOA, CONH2, CONHA, CONA2, NHCOA, NHCONH2, NHSO2A, CHO, COA, SO2NH2 and/or S(O)gA,
- Ar-A denotes aryl-alkyl
- A-Ar denotes alkyl-aryl
- HaI denotes F, Cl, Br or I,
- X denotes CH or N, where one group X in each compound of the formula I is N and two groups X are CH,
- Y denotes CH2 or a saturated bond,
- Z denotes CH or N, where at most two groups Z in each compound of the formula I are NH and preferably one or no group Z is NH,
- R2′, R2″, R2′″, R″″ each, independently of one another, denote H, HaI, OH, CN, NH2, unbranched or branched alkyl having 1-4, 5 or 6 C atoms, in which one CH2 group may be replaced by an O or S atom and/or by an NH, NA, CONH, NHCO or —CH═CH— group and/or, in addition, 1-4 H atoms may be replaced by HaI, and in which one CH3 group may be replaced by NH2, NAH, NA2, CN or Ar,
- R3 denotes H, A or Ar-A,
- g denotes 0, 1 or 2 and
- denotes a single or double bond,
- and pharmaceutically acceptable salts, derivatives, solvates and stereoisomers thereof, including mixtures thereof in all ratios.

Process for the preparation of compounds of the formula I and physiologically acceptable salts, derivatives, solvates and stereoisomers thereof, characterised in that
- a compound of the formula (ix)
- in which X has the meaning indicated for the formula I, is reacted with a compound of the formula (viii)
- in which Z, Y and R2 have the meanings indicated for the formula I, to give a compound of the formula (vii)
- which is, if desired, reduced to give a corresponding 2,3-dihydroindole compound, which is, in a next step, converted into a compound of the formula (vi)
- to which, if desired, a radical R1 and/or a radical R3 is also attached to give a compound of the formula (iii)
- and, if desired, a base or acid of the formula (iii) is converted into one of its salts,
- where, if the linking of the monocyclic aryl moiety to the bicyclic aryl moiety via its 2-position to give a compound of the formula (ii)
- is desired, a compound of the formula (viii) containing no silyl group is employed in the first step.
