Procedure

The title compound was prepared in similar fashion from (S)-(+)-4-(oxiranylmethoxy)-1H-indole and 4-(phenoxy)piperidine. The resulting free base was dissolved in ethyl acetate, and precipitated with one equivalent of oxalic acid in ethyl acetate in 69% overall yield. FDMS m/e=366 (M+ of free base). α[D]589 =-14.29 (c=0.5, methanol).
