Procedure

The title compound was prepared in similar fashion from (S)-(+)-4-(oxiranylmethoxy)-1H-indole and 1-(2-trifluoromethylphenyl)piperazine. The resulting free base was dissolved in ethyl acetate, and precipitated with one equivalent of oxalic acid in ethyl acetate in 70% overall yield. mp 123-124°. FDMS m/e=419 (M+ of free base). α[D]589=−7.0 (c=0.66, methanol).
