Bromination of Pyrimidines by N-Bromosuccinimide. III. Bromination of Anilino-and Phenoxypyrimidines

Abstract

2-Aminopyrimidines were brominated at their C₅-positions predominantly with NBS in carbon tetrachloride in spite of the presence of an anilino-, haloanilino-, or phenoxygroup at their C₆-positions as substituents.
