Adding a certain compound to certain chemical reactions, such as: 31737-09-4, 6-Chloro-1-methylpyrimidine-2,4(1H,3H)-dione, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Product Details of 31737-09-4, blongs to pyrimidines compound. Product Details of 31737-09-4
To a stirred solution of 6-chloro-1-methyl-1,2,3,4-tetrahydropyrimidine-2,4-dione (3 g, 18.68 mmol, 1 equiv.) and tert-butyl piperazine-1-carboxylate (4.2 g, 22.42 mmol, 1.2 equiv.) in EtOH (60 mL) was added NaHCO3(3.1 g, 37.37 mmol, 2 equiv.) at room temperature. The mixture was stirred at 70 degrees Celsius for 5 h. The mixture was concentrated under reduced pressure. The residue was purified by silica gel column chromatography, eluted with CH2Cl2/ MeOH (15:1 to 10:1) to afford tert-butyl 4-(3-methyl-2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4- yl)piperazine-1-carboxylate(5.38 g, 92.78%) as a white solid.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,31737-09-4, 6-Chloro-1-methylpyrimidine-2,4(1H,3H)-dione, and friends who are interested can also refer to it.
