In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of 4-amino-5-fluoropyrimidines and 5-amino-4-fluoropyrazoles from a β-fluoroenolate salt, published in 2020, which mentions a compound: 1416372-67-2, Name is 5-Fluoro-2-methylpyrimidin-4-amine, Molecular C5H6FN3, Recommanded Product: 5-Fluoro-2-methylpyrimidin-4-amine.
A synthesis of fluorinated pyrimidines I [R = H, OMe, Ph, etc.] under mild conditions from amidine hydrochlorides and potassium 2-cyano-2-fluoroethenolate was developed. A broad substrate scope was tested and mostly excellent yields were obtained. The synthesis of fluorinated aminopyrazoles from the same fluorinated precursor could be demonstrated but proceeded with lower efficiency.
There is still a lot of research devoted to this compound(SMILES：NC1=NC(C)=NC=C1F)Recommanded Product: 5-Fluoro-2-methylpyrimidin-4-amine, and with the development of science, more effects of this compound(1416372-67-2) can be discovered.
