The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 3993-78-0, name is 2-Amino-4-chloropyrimidine. This compound has unique chemical properties. The synthetic route is as follows. category: pyrimidines
General procedure: To a round-bottom flask was charged with the correspondingaromatic halogen (1.0 equiv), the corresponding boronic acid(1.05-1.25 equiv), Pd(dppf)Cl2 (0.05 equiv) and base Na2CO3 (2.0equiv) under nitrogen atmosphere, then 1,4-dioxane (14 mL) andwater (2 mL) were added and the vessel was immediately sealed tightly. The resulting mixture was heated at 95 C for a period time (usually 2-6 h) until the completion of the reaction as monitoredby TLC. The cooled mixture was diluted with water and exhaustively extracted with ethyl acetate (30 mL 3). The organic phase was washed by brine, dried over anhydrous Na2SO4, and evaporated under reduced pressure. The residue was purified by chromatography on silica gel using ethyl acetate/petroleum ether as the eluent to afford the products.
With the rapid development of chemical substances, we look forward to future research findings about 3993-78-0.
