Abstract

Abstract Butyrophenone compounds having excellent psychotropic activities represented by the formula: ##STR1## wherein R 1 is a halogen atom, R 2 is a lower alkyl group, and Z is a group of either one of the formulae: ##STR2## (wherein the dotted line indicates the optional presence of an additional single bond linkage, R 3 is a hydrogen atom or a hydroxyl group but only when said additional single bond linkage is not present and R 4 is a hydrogen atom or a phenyl or benzyl group optionally substituted with one or two substituents selected from the group consisting of halogen, lower alkyl, lower alkyoxy and trifluoromethyl on the benzene ring (except monohalophenyl)), ##STR3## (wherein the dotted line indicates the optional presence of an additional single bond linkage, R 5 is a hydrogen atom or a lower alkyl group and R 6 and R 7 are each a hydrogen atom, a halogen atom or a lower alkyl group), ##STR4## (wherein R 8 is a hydrogen atom or a lower alkyl group and R 9 is a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group), ##STR5## (wherein R 10 is a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group or a trifluoromethyl group), or ##STR6##
