Abstract
The invention relates to compounds of the general formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom or a C.sub.1-10 alkyl, C.sub.3-7 cycloalkyl, C.sub.3-7 cycloalkyl-(C.sub.1-4)-alkyl, C.sub.3-6 alkenyl, C.sub.3-10 alkynyl, phenyl or phenyl-(C.sub.1-3)alkyl group; one of the groups represented by R.sup.2, R.sup.3 and R.sup.4 is a hydrogen atom or a C.sub.1-6 alkyl, C.sub.3-7 cycloalkyl, C.sub.2-6 alkenyl or phenyl-(C.sub.1-3)alkyl group and each of the other two groups, which may be the same or different, represents a hydrogen atom or a C.sub.1-6 alkyl group; and X represents a halogen atom or a hydroxy, C.sub.1-4 alkoxy, phenyl-(C.sub.1-3)-alkoxy or C.sub.1-6 alkyl group or a group NR.sup.5 R.sup.6 or CONR.sup.5 R.sup.6 wherein R.sup.5 and R.sup.6, which may be the same or different, each represents a hydrogen atom or a C.sub.1-4 alkyl or C.sub.3-4 alkenyl group, or together with the nitrogen atom to which they are attached form a saturated 5 to 7 membered ring; and physiologically acceptable salts and solvates thereof. The compounds are potent and selective antagonists of "neuronal" 5-hydroxytryptamine receptors and are useful in the treatment of psychotic disorder…
