3-alkoxy-2-aminopropylamines compositions and use as cardiovascular agents

A propylamine of the following formula (I):

• ##STR6## wherein R.sup.1 is a lower alkyl group and R.sup.2 and R.sup.3 are joined to form a cycloalkyl group of about 3 to 7 carbons or R.sup.1, R.sup.2 and R.sup.3 are joined to form a polycyclicalkyl group of about 7 to 12 carbons;
• m is 0 or 1;
• A represents the atoms necessary to form a pyrrolidine, piperidine or morpholine ring;
• Y is independently selected from the group consisting of halo, alkyl, alkoxy, trifluoromethyl, hydroxy, or, when n is 2 on adjacent carbons, methylenedioxy;
• n is 0, 1, 2 or 3;
• and
• B represents the atoms necessary to form an aromatic heterocyclic ring, a saturated carbocyclic ring or an aromatic carbocyclic ring wherein said aromatic carbocyclic ring is either unsubstituted or is independently substituted by 1 or 2 of halo, alkyl, alkoxy, trifluoromethyl, hydroxy, monoalkylamino, dialkylamino or methylenedioxy;
• and the pharmaceutically acceptable acid addition salts thereof.
