113583-35-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 113583-35-0, name is 2-Methanesulfonyl-4,6-dimethoxypyrimidine, molecular formula is C7H10N2O4S, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
EXAMPLE 8 Preparation of Methyl 5-(4,6-Dimethoxypyrimidin-2-yl)oxy-2-ethoxy-2,3-dihydrobenzofuran-4-carboxylate (Compound No. 507) A mixture comprising 1.0 g of methyl 2-ethoxy-5-hydroxy-2,3-dihydrobenzofuran-4-carboxylate, 1.0 g of 4,6-dimethoxy-2-methylsulfonylpyrimidine and 0.78 g of potassium carbonate in 30 ml of N,N-dimethylformamide, was heated and stirred at 100 C. for two hours. The mixture was returned to room temperature, then poured into water and extracted with ethyl acetate. The organic layer was washed with water and then dried over anhydrous sodium sulfate. It was concentrated under reduced pressure, and the oily substance thereby obtained was purified by silica gel column chromatography (n-hexane/ethyl acetate=4/1) to obtain 1.5 g (yield: 95%) of the desired compound.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 113583-35-0, 2-Methanesulfonyl-4,6-dimethoxypyrimidine, other downstream synthetic routes, hurry up and to see.
