Jakubiec, Dominika; Przypis, Lukasz; Suwinski, Jerzy W.; Walczak, Krzysztof Z. published an article in 2017, the title of the article was Synthesis of 5-hetaryluracil derivatives via 1,3-dipolar cycloaddition reaction.Synthetic Route of 4433-40-3 And the article contains the following content:

1,3-Dipolar cycloaddition was applied for the synthesis 5-hetaryluracil derivatives where substituted uracils played the role of 1,3-dipoles or dipolarophiles. Treatment of the nitrile oxide derived from 5-formyluracil and substituted alkenes gave the appropriate 5-(4,5-dihydroisoxazol-3-yl)pyrimidine-2,4(1H,3H)-diones, which by oxidation with N-bromosuccinimide were transformed into appropriate 5-(isoxazol-3-yl)uracils. When 5-cyanouracil was used as a dipolarophile in the reaction with nitrile oxides, generated from aromatic aldoximes, several 5-(1,2,4-oxadiazol-5-yl)uracils were obtained. An alternative reaction of 5-formyluracil with an excess of nitriles in the presence of cerium ammonium nitrate as an oxidant gave 1,2,4-oxadiazol-3-yl derivatives in moderate yields. The experimental process involved the reaction of 5-(Hydroxymethyl)pyrimidine-2,4(1H,3H)-dione(cas: 4433-40-3).Synthetic Route of 4433-40-3
