Procedure

The title compound was prepared in similar fashion from (S)-(+)-4-(oxiranylmethoxy)-1H-indole and 3,4-dihydro-2-oxospiro[naphthalene-1(2H),4'-piperidine]. The resulting free base was dissolved in ethyl acetate, and precipitated with one equivalent of oxalic acid in ethyl acetate in 68% overall yield. FDMS m/e=404 (M+ of free base). α[D]589 =-15.81 (c=0.51, methanol).
