In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 113583-35-0, name is 2-Methanesulfonyl-4,6-dimethoxypyrimidine, the common compound, a new synthetic route is introduced below. 113583-35-0
General procedure: For the synthesis of 6-22 to 6-33, intermediate 5 (4.0 mmol),intermediate 2 or 3 (2.66 mmol) and tetrabutyl ammonium bromide(0.3 mmol) were added to 50 mL 90% ethanol. After that the reaction continued for 15 h under reflux and every 2 h the pH value of the mixture was adjusted to >7 by adding saturated sodium bicarbonate solution. The crude product was further extracted three times by using sodium hydroxide solution and ethyl acetate.The aqueous layer was then adjusted by hydrochloric acid to a pH value of 3-4. The product was extracted by ethyl acetate and finally purified by flash column chromatography using dichloromethane/methanol (80:1) and the yields were in the range of 14%-35%.
Statistics shows that 113583-35-0 is playing an increasingly important role. we look forward to future research findings about 2-Methanesulfonyl-4,6-dimethoxypyrimidine.
