PHARMACOLOGICALLY ACTIVE PYRIMIDINEAMINE DERIVATIVES AND PROCESSES FOR THE PREPARATION THEREOF

Described are N-phenyl-2-pyrimidineamine derivatives of formula (I) wherein R1 is a substituted cyclic radical, the cyclic radical being bonded to a ring carbon atom in each case and being selected from phenyl, pyridyl, pyrazinyl, thiazolyl, pyrimidinyl, pyridazinyl and imidazolyl, and the substituents of the above-mentioned cyclic radical being selected from one or more of the groups halogen, cyano, carbamoyl, -C(=O)-OR3, -C(=O)-R4, -SO2-N(R5)-R6, -N(R 7)- R8, -OR9 and fluorine-substituted lower alkyl, wherein R3, R4, R5, R6, R7, R 8 and R9 are each independently of the others hydrogen or lower alkyl that is unsubstituted or substituted by mono- or di-lower alkylamino; and R2 is selected from halogen, cyano, carbamoyl, -C(=O)-OR10, -C(=O)-R11, -SO2-N(R12 )- R13, -N(R14)-R15, -OR16 and fluorine-substituted lower alkyl, wherein R10, R11, R12, R13, R14, R15 and R16 are each independently of the others hydroge n or lower alkyl that is unsubstituted or substituted by mono- or di-lower alkylamino. Those compounds can be used, for example, in the treatment of tumour diseases.
