Reaction Steps

The title compound was prepared in similar fashion from (S)-(+)-4-(oxiranylmethoxy)-1H-indole and 4-(4-trifluoromethoxyphenyl)piperidine. The resulting free base was dissolved in ethyl acetate, and precipitated with one equivalent of oxalic acid in ethyl acetate in 76% overall yield. FDMS m/e=434 (M+ of free base). α[D]589 =-13.45 (c=1.04, methanol).
