Pyrimidines. Part 53. Novel Ring Transformation induced by the Substituent Effect of the Phenyl Group. Reaction of 5-Bromo-6-methyl-1-phenyluracil Derivates with Amines and Hydrazine to give Hydantoins and Pyrazolones

Reaction of 5-bromo-6-methyluracil derivates (1), possessing a phenyl or para-substituted phenyl group at the 1-position of the uracil ring, with methylamine or hydrazine hydrate causes novel ring transformations to give 1-arylhydantoins (2) and 4-ureidop
