I have a reaction in (H2O and Ethanol), which results a solid that can be solved in DMSO and hot ethanol.while Barbituric acid can be solved in hot ethanol too.How to separate barbituric acid from reaction?

(target molecule) is barbituric acid. The problem is separation of excessive barbituric acid from reaction.
I just wanted to gratuitously comment that I love your answers discodermolide! Wish I was as smart as you!
