The invention concerns the preparation of compounds of formula ##STR1## and acid addition and quaternary ammoniun salts thereof, wherein the dotted line represents an optional bond, Ar represents a ring system of formula ##STR2## in which Q is O, S, --CR.sup.7 .dbd.CR.sup.8 --, --N.dbd.CR.sup.8 -- and --N.dbd.N--; R.sup.4, R.sup.5 and R.sup.6, and R.sup.7 and R.sup.8 when present, each represent hydrogen or a substituent selected from lower alkyl, lower alkenyl, lower alkoxy, NO.sub.2, NH.sub.2, haloloweralkyl, hydroxyloweralkyl, aminoloweralkyl, substituted amino, halogen, loweralkoxycarbonyl, cyano, CONH.sub.2 and hydroxy; and additionally either R.sup.4 and R.sup.5 when adjacent or R.sup.6 and R.sup.8 when adjacent, together with the carbon atoms to which they are attached also represent a fused five or six membered carbocylic or heterocyclic ring optionally carrying one or more substituents as defined above; R is an optionally substituted aryl or heteroaryl radical or a cycloalkyl radical containing 5 to 7 carbon atoms; R.sup.1, R.sup.2, R.sup.3 and R.sup.9 are each hydrogen or a lower alkyl group; n is 0 or 1; X is .dbd.O, .dbd.S or .dbd.NH; Y is --O-- or a direct bond and Z is -- CO-- or --CH.sub.2 --, with the proviso that when Ar is unsubstituted phenyl and R.sup.9 is hydrogen then Y is --O--. The compounds of formula I exhibit psychotropic activity and are useful as antidepressants.
