Valine_Leucine

Hey people, I want to run a Fmoc deprotection of my peptide. The point is that I have an azide group in the side chain of the last aminoacid that I attached. Usually I run it with 20% piperidine in DMF but I am afraid about a possible reaction between the azido group and the free amino group after deprotection. I mean, which influence could have piperidine after the Fmoc deprotection in a possible reaction between azide and amino group (piperidine is a nucleophilic base...) Thanks in advance...
