Production Example 9 was repeated except that 5-bromo-2-methoxytoluene and 1-(2-phenethyl)piperazine were replaced with 1-benzyloxy-4-bromo-2-chlorobenzene (7.138 g) and piperazine (12.404 g), respectively. Thus obtained crude product was purified on silica gel column chromatography (eluent, chloroform: methanol=5:2) to provide 1-(4-benzyloxy-3-chlorophenyl)piperazine (4.739 g).
