Adrenergic blocking agents

Abstract

There are disclosed compounds of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of lower alkyl; R.sub.8 is selected from the group consisting of --O--(CH.sub.2).sub.n -- wherein n is 2 to 20, ##STR2## and R.sub.6 is selected from the group consisting of hydrogen or lower alkoxy, and ##STR3## wherein R.sub.1 is selected from the group consisting of lower alkyl; R.sub.8 is selected from the group consisting of --O--(CH.sub.2).sub.n -- wherein n is 2 to 20, ##EQU1## and R.sub.6 is selected from the group consisting of hydrogen or lower alkoxy and racemates thereof. There are also disclosed processes and intermediates utilized to produce the end products. The end products have utility as agents exhibiting both .alpha. and selective .beta. adrenergic blocking action.
