Synthetic Route of 53484-16-5,Some common heterocyclic compound, 53484-16-5, name is 6-Bromo-1-methyl-1H-benzo[d]imidazole, molecular formula is C8H7BrN2, 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.
To a solution of intermediate 5 (2.5g, 11.8 mmol) in dioxane (100ml) were addedtributyl(vinyl)tin (5,2ml, 18 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.69g, O.Smmol) and the mixture was heated under reflux for 24 hours and then concentrated under reduced pressure. The residue was purified by chromatography on silica gel, eluting with CH2CI2/MeOH (95/5). The title compound was obtained as an oil (1.8g, 96.1percent); NMR H1 (300MHz, CDCI3, ppm) 5: 7.9 (s, 1H), 7.75 (d, 1H), 7.4 (m, 2H), 6.85 (dd, 1H), 5.8 (d, 1H), 5.25 (d, 1H), 3.85 (s, 3H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6-Bromo-1-methyl-1H-benzo[d]imidazole, its application will become more common.
