Can you help me with synthesis of this fragment? I need help for my qualification work, but I can't find any scholarly article on synthesis...
I have no idea for a book or article, I tried researchgate, medicinaljournal, pubmed, sciencedirect etc. and nothing.

I would by very grateful for you.

Really?  If you search "N-phenylpiperazine synthesis" in just a web browser I get lots of hits.
