Abstract

There are described N-phenyl-2-pyrimidinamine derivatives of the formula I <IMAGE> in which R1 denotes 4-pyrazinyl, 1-methyl-1H-pyrrolyl, phenyl substituted by amino or amino-lower alkyl, in which the amino group is in each case free, alkylated or acylated, 1H-indolyl or 1H-imidazolyl bonded to a five-membered ring carbon atom, or pyridyl which is bonded to a ring carbon atom, unsubstituted or substituted by lower alkyl and unsubstituted or substituted by oxygen on the nitrogen, R2 and R3 independently of one another each denote hydrogen or lower alkyl, one or two of the radicals R4, R5, R6, R7 and R8 each denote nitro, fluorine-substituted lower alkoxy or a radical of the formula II -N(R9)-C(=X)-Y)n-R10 (II> in which R9 stands for hydrogen or lower alkyl, X stands for oxo, thio, imino, N-lower alkylimino, hydroximino or O-lower alkylhydroxyimino, Y stands for oxygen or the group NH, n stands for 0 or 1 and R10 stands for an aliphatic radical having at least 5 C atoms or for an aromatic, aromatic-aliphatic, cycloaliphatic, cycloaliphatic-aliphatic, heterocyclic or heterocyclic-aliphatic radical, and the remainder of the radicals R4, R5, R6, R7 and R8 independently of one another each denote hydrogen, lower alkyl which is unsubstituted or substituted by free or alkylated amino, piperazinyl, piperidinyl, pyrrolidinyl or morpholinyl, lower alkanoyl, trifluoromethyl, free, etherified or esterified hydroxyl, free, alkylated or acylated amino or free or esterified carboxyl. These compounds can be used e.g. for the therapy of cancers.
