Adding a certain compound to certain chemical reactions, such as: 84712-08-3, name is 5-Bromo-1-methyl-1,3-dihydro-2H-benzo[d]imidazol-2-one, 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 84712-08-3, Product Details of 84712-08-3
Step 3: A mixture of 5-bromo-1-methyl-1H-benzo[d]imidazol-2(3H)-one (300 mg, 1.32 mmol), bis(pinacolato)diboron (403 mg, 1.58 mmol) and potassium acetate (389 mg, 3.96 mmol) in 1,4-dioxane (4.5 mL) was sparged with nitrogen while stirring for 10 min. Dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) methylene chloride adduct (193 mg, 0.264 mmol) was then added and the reaction stirred at 100 C. for 1.5 h. After this time, the mixture was cooled to room temperature, partitioned between ethyl acetate and water and filtered through diatomaceous earth. The filter cake was washed with ethyl acetate and the filtrate layers separated. The organic phase was washed with water and dried over sodium sulfate. The drying agent was removed by filtration and the filtrate concentrated under reduced pressure. The resulting residue was purified by chromatography (silica, gradient, methylene chloride to 1:1 methylene chloride/ethyl acetate) to afford 1-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-2(3H)-one (7.44).
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, 5-Bromo-1-methyl-1,3-dihydro-2H-benzo[d]imidazol-2-one, other downstream synthetic routes, hurry up and to see.
