HCID 40862031-Benzoyl-4-(4-hydroxyphenyl)piperazineYield 76.7%

Procedure

Production Example 2 was repeated except that 1-(4-methoxyphenyl)-4-phenethylpiperazine was replaced with 1-benzoyl-4-(4-methoxyphenyl)piperazine (193 mg), and the resulting crude product was purified on TLC (developer, chloroform: acetone=4:1) to provide 1-benzoyl-4-(4-hydroxyphenyl)piperazine (141 mg).

Workup

  1. customthe resulting crude product was purified on TLC (developer, chloroform: acetone=4:1)
