This compound was prepared in a manner analogous to that of Step B of Example 3, with 0.5 gram (0.0016 mole) of ethyl N-(4-fluoroindol-3-ylmethyl)piperidin-4-ylcarboxylate, 2.0 grams (0.0082 mole) of 4-trifluoromethoxyphenyl bromide, and 0.2 gram (0.0086 gram-atom) of magnesium turnings in about 10 mL of diethyl ether as reagents. The crude reaction product was taken up in hexane. The hexane-insoluble material was collected by filtration and purified by preparative thin layer chromatography with 1:3 ethyl acetate:hexane as an eluant, yielding about 0.09 gram of N-(4-fluoroindol-3-ylmethyl)-4-[bis(4-trifluoromethoxyphenyl)hydroxymethyl]piperidine, mp 76°-88° C. The NMR spectrum was consistent with the proposed structure.
