Step (b) of Example 1 was repeated, except that 4,4-bis(4-fluorophenyl)butyl bromide was used instead of 3,3-diphenylpropyl bromide and the compound prepared in step (a) of Example 80 was used instead of ethyl 3-piperazin-1-yl-benzoate. Thus, ethyl 4-[4-[4,4-bis(4-fluorophenyl)-1-butyl]piperazin-1-yl]benzoate was obtained.
