You gotta keep that thing pretty cold or else it will undergo spontaneous Curtius rearrangement

That looks pretty cool.
So, the acid azide is just heated with amine to get the amide?

ah I see, with heating I get the courtious rearangement, not that this wouldnt be interesting as well, to get some urea derivatives there

If you have some DMAP as catalyst you probably dont need heating.

Do you have some literature examples of the azide :rarrow: amide tranformation?

No, sorry. But this is an old reaction, also used i peptide synthesis, if you search on Scifinder etc. you will get hits.
