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., 113583-35-0
EXAMPLE 1 Preparation of methyl 3-[(4,6-dimethoxypyrimidin-2-yl)oxy]-6-(1-pyrrolidinyl)picolinate (Compound No. 317) 1.55 g (7 mmol) of methyl 3-hydroxy-6-(1-pyrrolidinyl)picolinate, 1.83 g (8.4 mmol) of 4,6-dimethoxy-2-methylsulfonylpyrimidine and 0.96 g (7 mmol) of potassium carbonate were added to 50 ml of DMF and reacted at 100C for 3 hours. After completion of the reaction, the reaction product was poured into ice water, extracted with ethyl acetate, washed with a saturated sodium chloride aqueous solution and dried over magnesium sulfate. The solvent was distilled off, and the residue was crystallized from diisopropyl ether to obtain the desired product. Amount: 2.11 g (yield: 84%), melting point: 151-153C
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.
