Adding a certain compound to certain chemical reactions, such as: 14331-54-5, 2,4-Dimethylpyrimidine, 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, Recommanded Product: 2,4-Dimethylpyrimidine, blongs to pyrimidines compound. Recommanded Product: 2,4-Dimethylpyrimidine
2-Chloro-4-methyl-pyrimidine. A mixture of 2,6-dichloropyrimidine (1.5 g, 10.07 mmol), trimethylaluminum (0.87 g, 12.08 mmol), tetrakis(triphenylphosphine)palladium(0) (0.81 g, 0.7 mmol) in THF (30 mL) was heated under reflux for several hours. The reultant mixture was quenched with addition of water. (Note: allowing reaction to go overnight was detrimental). The product mixture was extracted with ethyl acetate three times, dried over sodium sulfate, filtered and concentrated to give a dark yellow oil. The resultant oil was purified by flash chromatography on silica gel (hexane/ethyl acetate) to give title compound as a light yellow solid. 1H NMR (400 MHz, DMSO) delta 8.62-8.61 (d, j=5.1 Hz, 1 H), 7.47-7.46 (d, j=5.1 Hz, 1 H), 2.56 (s, 3H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,14331-54-5, 2,4-Dimethylpyrimidine, and friends who are interested can also refer to it.
