Application of 313339-35-4, 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. 313339-35-4, name is 4,6-Dichloro-2-(methylthio)pyrimidine-5-carboxylic acid. A new synthetic method of this compound is introduced below.
Step 1.1 : (preparation of a compound of formula (X)) 4,6-Dichloro-2-methylsulfanylpyrimidine-5-carbonyl chloride 10 g of 4,6-dichloro-2-methylsulfanylpyrimidine-5-carboxylic acid (41.83 mmol) are placed in 61 ml of thionyl chloride (836.54 mmol) with stirring. After 18 hours at 80C, the thionyl chloride is evaporated off and the residue is taken up twice with 15 ml of toluene and concentrated to give 10.77 g of 4,6-dichloro-2-methylsulfanylpyrimidine-5-carbonyl chloride.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,313339-35-4, 4,6-Dichloro-2-(methylthio)pyrimidine-5-carboxylic acid, and friends who are interested can also refer to it.
