Versuchsvorschrift

Production Example 2 was repeated except that 1-(4-methoxyphenyl)-4-phenethylpiperazine was replaced with 4-(2,5-difluoro-4-methoxyphenyl)-1-phenethylsulfonylpiperazine (401 mg). The resulting crude product was purified on TLC (developer, hexane: ethyl acetate=2:1) to provide 4-(2,5-difluoro-4-hydroxyphenyl)-1-phenethylsulfonylpiperazine (255 mg).
