Versuchsvorschrift

The title compound was prepared according to Example 99 from 1-chloro-3-(1H-indole-4-oxy) propane and 4-(4-cyclopropylmethoxy-1H-indol-3-yl) piperidine (which was prepared by condensing 4-cyclopropylmethoxyindole with 4-piperidone monohydrate hydrochloride in refluxing methanol with potassium hydroxide, followed by reduction of the unsaturation with palladium on carbon in methanol). The resulting free base was dissolved in ethyl acetate, and precipitated with one equivalent of oxalic acid in ethyl acetate in 57% overall yield as a white foam. FDMS m/e=443 (M+ of free base).
