Adding a certain compound to certain chemical reactions, such as: 54624-57-6, name is 2-Bromobenzimidazole, 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 54624-57-6, COA of Formula: C7H5BrN2
Sodium hydride (60% dispersion in mineral oil, 0.665 g, 16.63 mmol) was added to a solution of 2-bromo-1H-benzo[d]imidazole (2.73 g, 13.86 mmol) in DMF (30 mL), and the reaction stirred for 10 minutes at ambient temperature. 1-Bromo-2-methoxyethane (1.541 ml, 16.63 mmol) was added, and reaction stirred overnight at ambient temperature. The reaction was diluted with ethyl acetate and washed several times with brine. The organic layer was separated and dried over anhydrous magnesium sulfate, filtered and concentrated. The residue was purified via column chromatography on a 100 gram silica gel column eluting with 20-40% ethyl acetate-hexane. The desired fractions were combined and concentrated to afford 2-bromo-1-(2-methoxyethyl)-1H-benzo[d]imidazole (2.9 g, 82%) as an orange oil. 1H NMR (300 MHz, DMSO-d6) delta ppm 7.54-7.67 (m, 2H) 7.14-7.34 (m, 2H) 4.42 (t, J=5.28 Hz, 2H) 3.67 (t, J=5.28 Hz, 2H) 3.20 (s, 3H).
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-Bromobenzimidazole, other downstream synthetic routes, hurry up and to see.
