[摘要]：Three methods for the regiospecific bromination of 2-phenyl-3H-pyrimidin-4-ones are presented: bromination of the 5-position of the pyrimidine ring, bromination of the 6-benzylic position, and simultaneous bromination of both the 5-position of the pyrimidine ring and 6-benzylic position. Reactions were carried out using simple protocols and the brominated pyrimidines were obtained in good yields.
