Versuchsvorschrift
Production Example 10 was repeated except that 1-(4-methoxy-3-methylphenyl)-4-phenethylpiperazine was replaced with 1-(3-cyclopentylpropyl)-4-(2,5-difluoro-4-methoxyphenyl)-piperazine (250 mg). The resulting crude product was purified on TLC (developer, chloroform: methanol=16:1) to provide 4-[4-(3-cyclopentylpropyl)piperazin-1-yl]-2,5-difluorophenol (83 mg).
