Reaction Steps

The title compound was prepared in similar fashion from (S)-(+)-4-(oxiranylmethoxy)-1H-indole and 7,8-dimethoxy-2,3,4,5-tetrahydro-1H-3-benzazepine. The resulting free base was dissolved in ethyl acetate, and precipitated with one equivalent of oxalic acid in ethyl acetate in 48% overall yield. FDMS m/e=396 (M+ of free base). α[D]589 =-9.34 (c=0.47, methanol).
