New N-heteroarylalkylenediamine ##STR1## wherein R.sub.1 and R.sub.2 each independently is hydrogen, an alkyl radical containing up to 6 carbon atoms, or a benzyl radical, X is an alkylene radical containing 2 to 6 carbon atoms, A is a mono- or bicyclic heteroaromatic radical, which can be partly hydrogenated, with the proviso that it contains 2 or 3 adjacent ring heteroatoms, whereby the bound ring heteroatoms can be an oxygen atom and a nitrogen atom or 2 or 3 nitrogen atoms, and R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 each independently is hydrogen, or an alkyl radical containing up to 6 carbon atoms, which can be substituted by hydroxyl, carbamyl, nitrile or carboxyl, an alkenyl radical containing 2 to 6 carbon atoms, a phenyl or carbamyl radical or one of the divalent substituents oxygen or sulphur, or a salt thereof. The compounds are intermediates in the synthesis of cardioactive compounds.
