Abstract
Abstract This invention relates to phenoxyalkylamines having the formula: ##SPC1## In which n is zero or 1, R is hydrogen or a hydroxy group, R 2 is hydrogen, a hydroxy group or an alkyl group, R 2 being other than hydroxy when n is zero, A is a group ##EQU1## or ##EQU2## R 1 being hydrogen, a cycloalkyl group or an aryl group. Said phenoxyalkylamines possess coronary vasodilatator and cardiotonic properties.
