Adding a certain compound to certain chemical reactions, such as: 32779-38-7, 2-Chloro-5-iodopyrimidine, 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, COA of Formula: C4H2ClIN2, blongs to pyrimidines compound. COA of Formula: C4H2ClIN2
b) 2,5-dichloro-N-(3-((2-chloropyrimidin-5-yl)ethynyl)-2,4-difluorophenyl)benzenesulfonamide Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (0.56 g) was added to a solution of 2,5-dichloro-N-(3-ethynyl-2,4-difluorophenyl)benzenesulfonamide (3.0 g), 2-chloro-5-iodopyrimidine (2.6 g), DIPEA (3.0 mL) and copper(I) iodide (79 mg) in THF (50 mL) at room temperature. The mixture was stirred under a nitrogen atmosphere at room temperature for 16 hr. The reaction mixture was filtered through celite, and the filtrate was diluted with water and the mixture was extracted with ethyl acetate. The obtained organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated to give a residue. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (761 mg). 1H NMR (300 MHz, DMSO-d6) delta 7.22-7.32 (1H, m), 7.42 (1H, td, J=8.9, 5.9 Hz), 7.71-7.81 (2H, m), 7.87 (1H, dd, J=2.0, 0.8 Hz), 9.03 (2H, s), 10.83 (1H, s).
The synthetic route of 32779-38-7 has been constantly updated, and we look forward to future research findings.
