Piloty alloxazine synthesis

What is Piloty alloxazine synthesis?

The Piloty alloxazine synthesis involves the formation of an 8-aminobenzo[g]pteridine-2,4-(1H,3H)-dione through a ring-closure reaction between 5-(hydroxyimino)pyrimidine-2,4,6-(1H,3H,5H)trione, in a boiling aqueous NaOH, and benzene-1,3-diamine.
