Application

5-Chloro-2,4,6-trifluoropyrimidine can be used as a starting material to synthesize:
  • 4-azido-5-chloro-2,6-difluoro-pyrimidine by azidation reaction with sodium azide.
  • 5-chloro triphenoxy pyrimidine by reacting with tetraphenoxysilane in the presence of tetra butyl ammonium fluoride (TBAF).
  • 5-chloro-2,6-difluoropyrimidin-4-amine, and 5-chloro-4,6-difluoropyrimidin-2-amine (9:1 ratio) by reacting with ammonia.
  • 5-Chloro-N,N -diethyl-2,6-dipyrimidin-4-amine, by treating with diethylamine and DIPEA.
