Versuchsvorschrift

Production Example 10 was repeated except that 1-(4-methoxy-3-methylphenyl)-4-phenethylpiperazine was replaced with 1-(2-cyclohexylethyl)-4-(2,5-difluoro-4-methoxyphenyl)-piperazine (250 mg). The resulting crude product was purified on TLC (developer, chloroform: methanol=13:1) to provide 4-[4-(2-cyclohexylethyl)piperazin-1-yl]-2,5-difluorophenol (87 mg).
