실험 절차

Production Example 9 was repeated except that 5-bromo-2-methoxytoluene and 1-phenethylpiperazine were replaced with 4-bromo-2,5-difluoroanisole (338 mg) and 4-(3-cyclohexylpropyl)-piperidine (953 mg), respectively. The resulting crude product was purified on silica gel column chromatography (eluent, hexane: ethyl acetate=3:1) to provide 4-(3-cyclohexylpropyl)-1-(2,5-difluoro-4-methoxyphenyl)piperidine (523 mg).
