Synthesis
Crown ethers are able to enhance the performance of KF in two ways. Firstly,
they complex the potassium cation making a better fluoride source and secondly they
increase the solubility of KF in the solvent.
KF with a catalytic amount of dicyclohexano-18-crown-6 in tetraglyme converted
2,4-dichloropyrimidine into 2,4-difluoropyrimidine.
Uses
2,4-Difluoropyrimidine can be used as a starting material to synthesize:
- 3-Pyrimidin-4-yl-oxazolidin-2-one derivatives as mutant isocitrate dehydrogenase (IDH1) inhibitors.
- N,N′-(1,4-phenylenebis(methylene))bis(2-fluoropyrimidin-4-amine) as chemokine receptor type 4 antagonists.
