Reaction Steps

261 mg of 4-(4-trifluoromethoxyphenoxy)piperidine, 224 mg of 1,4-cyclohexanedione and 4 mg of 10% palladium-carbon were heated in ethanol and reacted at 70° C. to 80° C. for 9 hours. After the completion of the reaction, the resultant was separated by silica gel column chromatography (n-hexane:ethyl acetate=3:1) and 315 mg of 1-(4-hydroxyphenyl)-4-(4-trifluoromethoxyphenoxy)piperidine was obtained (yield 89%).
