Adding a certain compound to certain chemical reactions, such as: 213265-83-9, 4,6-Dichloro-5-fluoropyrimidine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Formula: C4HCl2FN2, blongs to pyrimidines compound. Formula: C4HCl2FN2
Stage 3 (0508) 4,6-Dichloro-5-fluoro-pyrimidine (1 eq), 3,4-dichlorophenyl boronic acid (0.7 eq) and Pd(PPh3)4 (0.05 eq) were suspended in 1,4-dioxane (20 vol). A 2M K2CO3 solution (6.75 vol) was added and the reaction mixture was heated at 90 C. with stirring for 2 hours under an atmosphere of N2. The reaction mixture was cooled to room temperature and concentrated in vacuo. The residue was dissolved in EtOAc and water. The mixture was partitioned and the aqueous layer further extracted with EtOAc. The combined organic layers were washed with saturated aqueous NaCl, dried over Na2SO4, filtered and the solvent removed in vacuo. The resulting residue was purified by flash column chromatography (eluent: [1:15] EtOAc:heptane) to afford the required target compound.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,213265-83-9, 4,6-Dichloro-5-fluoropyrimidine, and friends who are interested can also refer to it.
