Electric Literature of 113583-35-0, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 113583-35-0, name is 2-Methanesulfonyl-4,6-dimethoxypyrimidine. A new synthetic method of this compound is introduced below.
4-Hydroxypyridine 1.88g (0.02 mol) and 4,6-dimethoxypyrimidine-2-yl methyl sulfone 4.36g (0.02 mol) were dissolved in DMF 100 ml, and K2CO3 3.3g (1.2 eq) was added thereto. Then, the temperature was maintained at 95C while the mixture was stirred over night. The reacted solution was added to water 100 ml, extracted with diethyl ether, dried with MgSO4, and distilled under reduced pressure to obtain residue. Through purification with silica gel column chromatography, a solid material 3.73g (80%) was obtained: 1H NMR (CDCl3); 3.73 (s, 6H), 5.49 (s, 1H), 6.85-8.42 (m, 4H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,113583-35-0, 2-Methanesulfonyl-4,6-dimethoxypyrimidine, and friends who are interested can also refer to it.
