Some common heterocyclic compound, 2620-76-0, name is 2-(4-Bromophenyl)-1-phenyl-1H-benzoimidazole, molecular formula is C19H13BrN2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. name: 2-(4-Bromophenyl)-1-phenyl-1H-benzoimidazole
Preparation of Compound F[186] Compound F-2 (38.6g, 110mmol), potassium acetate (32.4g, 330mmol), bis(pinacolato)diboron (36.5g, 143mmol), 1,4-dioxane (390mL), and PdCl2(dppf) (1.8g, 2mmol) were mixed and stirred at 80 for 18 hours, and then cooled at room temperature. Water (400mL) was added to the reactant and stirred. After stirring, an organic layer was extracted by adding saturated sodium chloride aqueous solution and ethyl acetate, dried over magnesium sulfate, and treated with activated charcoal, followed by filtering with celite. A solid prepared by concentrating the filtrate under reduced pressure was re-crystallized, thereby obtaining Compound F (36g, 82%).[187] 1H NMR (CDCl3) d 7.92(d, 1H), 7.76(d, 2H), 7.59(d, 2H), 7.56-7.45(m, 3H), 7.41-7.29(m, 4H), 7.27(s, 1H), 1.35(s, 12H)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2620-76-0, its application will become more common.
