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. 49844-90-8, name is 4-Chloro-2-(methylthio)pyrimidine, the common compound, a new synthetic route is introduced below. Formula: C5H5ClN2S
5-methoxy-1H-indazole (500 mg, 3.38 mmol) was dissolved in DMF (10 mL). NaH (148 mg, 3.72 mmol) was added at 0 C, and then 4-chloro-2-(methylthio)pyrimidine (542 mg, 3.38 mmol) was added. After stirring at this temperature for 2 hours, 30 mL of water was added. The reaction solution was filtered, extracted and dried to obtain 5-methoxy-1-(2-(methylthio)pyrimidin-4-yl)-1H-indazole (850 mg, 92%) as a white solid.
The synthetic route of 49844-90-8 has been constantly updated, and we look forward to future research findings.
