hello,
I'm trying to synthesise this aldehyde. i followed the literature but i have problem in getting the product pure.
as i noticed that it tend to crystallise at the top of the flask when i remove the solvent by rotavap, i was thinking i could sublime it (mp = 68 bp = unknown)
any good suggestions???

Ok what kind of quantity are we talking about Michela?

Pyrimidine carboxaldehydes do tend to sublime pretty well. I'd give it a shot.

order of mg not too much unfortunately !
if i don't know the boiling point how can i try to sublimate it ??
thanks
