Dear friends,

Please suggest me a method to protect the hydroxyl
group of 2-hydroxyethyl piperazine. Actually I have
tried with DHP with pyridiniumparatoluenesulfonate as
catalyst.

I have stirred the reaction mixture for about 8 hrs.
no reaction occured. after that i have refluxed the
reaction mixture for about 4 hrs. even then no
reaction occured. is there any problem with the
secondary amine functionality present in the
piperazine moiety.

Thanks in advance
