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. 53484-15-4, name is 5-Bromo-1-methyl-1H-benzo[d]Imidazole, A new synthetic method of this compound is introduced below., Product Details of 53484-15-4
Into a 250-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 4-(tetramethyl-l ,3,2-dioxaborolan-2-yl)benzoic acid (2.35 g, 9.47 mmol, 1.00 equiv) in CH3CN/toluene (70/12 mL), 5-bromo- l-methyl- lH- benzo[d] imidazole (2 g, 9.48 mmol, 1.00 equiv), Pd(PPh3)4 (548 mg, 0.47 mmol, 0.05 equiv), sodium carbonate (0.4M, 50 mL, 2.00 equiv). The resulting solution was stirred for 18 h at 90C. After cooled to room temperature, the reaction mixture was poured into 50 ml of water. The mixture was washed with 2×100 mL of ethyl acetate and the aqueous layer was collected. The pH value of the solution was adjusted to 4 with hydrochloric acid (IN). The solids were collected by filtration and dried under vacuum. This resulted in 2 g (84%) of the title compound as a white solid, which was dried under vacuum. LC- MS (ES, m/z): 253 [M+H]+
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
