An improvedmethod for the synthesis of N1-substituted oroticacid derivatives is reported. The method involves sequential incorporation of nitrogen atoms to the pyrimidine structure from simple starting materials and thus allows the synthesis of N1-substituted oroticacid derivatives with single 15N label at either N-1 or N-3.
