4-((alpha-S)-alpha-((2S,5R)-2,5-Dimethyl-4-(4-fluorobenzyl)-1-piperazinyl)benzyl)-N,N-diethylbenzamide was prepared from 4-((alpha-S)-alpha-((2S,5R)-2,5-dimethyl-1-piperazinyl)benzyl)-N,N-diethylbenzamide (Example 1) and 4-fluorobenzyl bromide by a procedure similar to that described in Example 1. Calc. for C31H38FN3O: C, 76.35; H, 7.85; N, 8.62; F, 3.90.
