Adding a certain compound to certain chemical reactions, such as: 2620-76-0, name is 2-(4-Bromophenyl)-1-phenyl-1H-benzoimidazole, belongs to imidazoles-derivatives compound, 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 2620-76-0, HPLC of Formula: C19H13BrN2
[0104] Compound 26: A mixture of Compound 25 (4- (diphenylamino)phenyl)boronic acid (900 mg, 3.1 mmol), Compound 9 (1.09 g, 3.1 mmol), Pd(PPh3)4 (180 mg, 0.16 mmol) and K2CO3 (1.38 g, 10 mmol) in 1,4- dioxane/H2O (25 mL/5 mL) was degassed and the resulting mixture was heated at about 100 0C overnight under an argon atmosphere. After cooling to room temperature, the resulting mixture was poured into water, extracted with ethyl acetate (100 mL x 2). The organic phase was dried over Na2SO4 and filtered. After addition of hexanes (100 mL), a yellow precipitate formed after about one hour. Filtration gave a yellow solid (760 mg) and the filtrate was absorbed on silica gel and purified by flash chromatography to give a yellow solid (200 mg). The total amount of product (Compound 26) was 960 mg in 62% yield.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-(4-Bromophenyl)-1-phenyl-1H-benzoimidazole, other downstream synthetic routes, hurry up and to see.
