The procedure of step (b) of Example 1 was repeated, except that the compound prepared in step (a) of Example 87 was used instead of 3,3-diphenylpropyl bromide and the compound prepared in step (a) of Example 53 was used instead of ethyl 3-piperazin-1-yl-benzoate. Thus, ethyl 3-[4-[4-[9-(2,2,2-trifluoroethylcarbamoyl)-9H-fluoren-9-yl]butyl]piperazin-1-yl]-2-methylbenzoate was obtained.
