Dear pals,
Could any one suggest me why the following reaction does not work.
1. I have reacted piperazine (2 mole) with n-propyl bromide (1 mole) to
give n-propyl piperazine. The reaction was carried out in ethanol (under
reflux)with 1 mole of NaOH for 7 hrs.  Unfortunately, what i obtained
was the disubstituted product and unreacted piperazine.

I could be much greatly if you'll could offer me other procedure to
synthesize the above mentioned compound.  I would also like to know on
the commercial availability of theis compound.  Any other suggestion is
welcome.

Thanks in advance.

Regards,
Roshan.
