Here, we report a metal-free cross-coupling reaction of diazines and related heteroarenes with organoboron species via C-H functionalization. The optimized conditions represent a metal-free method for the activation of aryl/heteroarylboronic acids, which undergo coupling with diazines and related heteroarenes. Optimized conditions also find application in the synthesis of a pyrimidine-based potent CDK inhibitor, meriolin1.

This invention relates to methods for treating or preventing hepatitis C virus infections in mammals using Toll-Like Receptor (TLR)7 ligands and prodrugs thereof. More particularly, this invention relates to methods of orally administering a therapeutically effective amount of one or more prodrugs of TLR7 ligands for the treatment or prevention of hepatitis C viral infection. Oral administration of these TLR7 immunomodulating ligands and prodrugs thereof to a mammal provides therapeutically effective amounts and reduced undesirable side effects.

The diazotation of 2-aminopyrimidines and their N-oxides in solutions with various acidities was studied.It is shown that the amino group in pyrimidine N-oxides is not diazotized in strongly acidic media and that bromination in the 5 position of the pyrimidine ring is observed in concentrated hydrobromic acid.When the reaction was carried out in moderately acidic media, it was possible to synthesize the difficult-to-obtain 2-halopyrimidine N-oxides.
