Abstract
Described herein are D4 receptor-selective compounds of the formula: ##STR1## wherein R.sup.1 is selected from H and an acid labile protecting group; and R.sup.2 and R.sup.3 are independently selected from H, radioisotopic halo, loweralkoxy and tri(loweralkyl)tin; and salts, solvates or hydrates thereof. Also described is the use of these compounds as pharmaceuticals to treat indications for which a dopamine D4 receptor antagonist is indicated. Radiolabeled compounds are useful particularly to image localization of D4 receptor in the human brain, and can therefore aid in the diagnosis of schizophrenia and other medical conditions in which the D4 receptor is implicated.
