Novel heteroaromatic amine derivatives, medicaments containing these compounds and processes for their preparation

The present invention relates to novel heteroaromatic amine derivatives of the general formula in which A is a -CH2-CH2-, -CH=CH- or -CH2-CO group and B is a methylene, carbonyl or thiocarbonyl group or A is a -CO-CO- or group and B is a methylene group, E is a straight-chain alkylene group which is optionally substituted by an alkyl group, G is a straight-chain alkylene group which is optionally substituted by an alkyl group, R1 is a hydrogen, chlorine or bromine atom, or a trifluoromethyl, nitro, amino, alkylamino, dialkylamino, alkyl, hydroxyl, alkoxy or phenylalkoxy group, R2 is a hydrogen, chlorine or bromine atom, or a hydroxyl, alkoxy, phenylalkoxy or alkyl group, or R1 and R2 together are an alkylenedioxy group, R3 is a hydrogen atom, or an alkenyl, an alkyl or phenylalkyl group and Het is a 5- or 6-membered heteroaromatic ring bonded via a carbon or nitrogen atom and which contains an oxygen, sulphur or nitrogen atom, two nitrogen atoms or a nitrogen atom and an oxygen or sulphur atom, or an imidazo[1,2-a]pyridyl group in which the carbon skeleton of the abovementioned heteroaromatic radicals can be mono- or disubstituted by a halogen atom or an alkyl, hydroxyl, alkoxy, phenylalkoxy, phenyl, dimethoxyphenyl, nitro, amino, acetylamino, carbamoylamino, N-alkylcarbamoylamino, hydroxymethyl or alkoxymethyl group or substituted by a methylenedioxy group and at the same time an imino group which may be present in the abovementioned heteroaromatic radicals [lacuna] by a ...
