Versuchsvorschrift

Production Example 9 was repeated except that 5-bromo-2-methoxytoluene and 1-(2-phenethyl)piperazine were replaced with 4-bromo-2,5-difluoroanisole (446 mg) and 4-(3-phenylpropyl)-piperidine (1.220 g), respectively. The resulting crude product was purified on silica gel column chromatography (eluent, hexane: ethyl acetate=8:1) to provide 1-(2,5-difluoro-4-methoxyphenyl)-4-(3-phenylpropyl)piperidine (233 mg).
