Electric Literature of 113583-35-0, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.113583-35-0, name is 2-Methanesulfonyl-4,6-dimethoxypyrimidine, molecular formula is C7H10N2O4S, molecular weight is 218.23, as common compound, the synthetic route is as follows.
Process for producing 3-[(4,6-dimethoxypyrimidin-2-yl)oxy]-6-methylaminopicolinic acid (Second method) 10.5 mg (0.0576 mmol) of methyl 6-methylamino-3-hydroxypicolinate, 11.6 mg (0.0532 mmol) of 2-methylsulfonyl-4,6-dimethoxypyrimidine, 8.8 mg (0.637 mmol) of potassium carbonate and 0.5 ml of dry dimethylsulfoxide were mixed. The mixture was stirred at room temperature for 5 hours, and then a 10% potassium hydroxide aqueous solution (corresponding to 90 mg, 0.160 mmol) was added thereto. The mixture was reacted at room temperature for one hour, and then 2.0 ml of water was added to the reaction mixture. Further, 1.0 ml of a 10% citric acid aqueous solution was added thereto, and the mixture was left to stand, whereby crystals precipitated. After being thoroughly precipitated, the crystals were filtered under suction and washed with water. The crystals were dried to obtain 3-[(4,6-dimethoxypyrimidin-2-yl)oxy]-6-methylaminopicolinic acid. Colorless prism crystals, 13.7 mg (yield: 84.0%)
The chemical industry reduces the impact on the environment during synthesis 113583-35-0, I believe this compound will play a more active role in future production and life.
