Abstract: Aminoalkyl and acylaminoalkyl ethers which are distinguished by high affinity for the bradykinin B.sub.2 receptor and improved solubility in water are described. These aminoalkyl and acylaminoalkyl ethers can be represented by the formula (I) ##STR1## in which R.sup.1,R.sup.2,R.sup.3 are alkyl, aryl, alkylaryl, halogen, hydrogen, cycloalkyl, CHO, CO--O-alkyl, COOH; R.sup.4, R.sup.5 are hydrogen, halogen, alkoxy, nitro, cyano, S-alkyl; n is a number from 1 to 8; R.sup.6 is hydrogen, alkyl, alkylalkenyl, alkylaryl; R.sup.7 is hydrogen and a substituted or unsubstituted acyl radical. A process for preparing the compounds of the formula (I) is likewise described.
