Reaction Steps

The title compound was prepared in similar fashion from 1-chloro-3-(1H-indole-4-oxy)propane and 4-(4-cyclopropyl-methoxy-1H-indol-3-yl)-1,2,3,6-tetrahydropyridine (which was prepared by condensing 4-cyclopropylmethoxyindole with 4-piperidone monohydrate hydrochloride in refluxing methanol with potassium hydroxide). The resulting free base was dissolved in ethyl acetate, and precipitated with one equivalent of oxalic acid in ethyl acetate in 20% overall yield as a white foam. FDMS m/e=441 (M+ of free base).
