Abstract
The present invention provides compounds of the formula ##STR1## or a pharmaceutically acceptable salt thereof wherein R.sub.1 is selected from hydrogen, halo, lower alkyl, lower alkoxy, or thioalkoxy; and R.sub.2 is lower alkoxy; or R.sub.1 and R.sub.2 together form a methylenedioxy or ethylenedioxy ring; R.sub.3 and R.sub.4 are independently selected from hydrogen, hydroxy, lower alkyl, lower alkoxy, lower alkylthio, (lower alkyl)amino, (lower alkylsulfonyl)amino, and halo; and R.sub.7 is selected from the group consisting of 2- or 3-thienyl, 2- or 3-furyl, and ##STR2## where R.sub.13 and R.sub.14 are independently selected from the group consisting of hydrogen, hydroxy, halogen, amino, lower alkyl, lower alkoxy, lower alkylthio, methylenedioxy, or ethylenedioxy. The compounds of the present invention selectively inhibit .alpha..sub.2 -adrenergic receptors as well as inhibit the uptake of biogenic amines and are thus useful in the treatment of certain cardiovascular and psychiatric disorders.
