What is 4,5,6-Trifluoropyrimidine?
4,5,6 trifluoropyrimidine is a Halogenated Heterocyclesan. It is a building block and intermediate that is very valuable in the synthesis of new fungicide. The study of its preparation and feasible development process for industrial manufacturing is very meaningful for practice.
Preparation of 4,5,6-trifluoro-pyrimidine
Use 4,6-dichloro-5-fluorine pyrimidine as a raw material and reacting under ordinary pressure with a fluorinated reagent, a phase-transfer catalyst and a high-polarity aprotic solvent. The advantages of the preparation method are that the reaction process conditions are simple, the reaction temperature is low, the reaction time is short, and the production cost is low because that reaction under ordinary pressure exempts the reaction from high-pressure equipment. More importantly, the yield of the obtained product is as high as more than 80% and the purity can be higher than 97%.
