Uses
5-Bromo-2-methyl-1H-benzo[D]imidazole is a benzo[D]imidazole derivative. Benzimidazole compounds possess biological activities such as anti-HIV-1 activity, anti-tumor activity, anti-cell proliferation activity, anti-parasitic activity, anti-inflammatory activity, antioxidant activity, and anti-epileptic activity. In addition, these compounds are also used as metal ligands. Therefore, the synthesis of these compounds has attracted considerable attention from chemists.
Synthesis
GENERAL METHOD: A mixture of 4-bromophthalimide (1.0 mmol), triethyl orthoacetate (1.2 mmol) and ZrCl4 (0.1 mmol) in 10 mL of methanol was stirred at room temperature for 3 hours. Upon completion of the reaction, the progress was monitored by TLC and the solvent was removed by concentration under reduced pressure. The crude product was purified by silica gel column chromatography with an eluent ratio of petroleum ether/ethyl acetate (4:1 to 1:1, v/v) to afford the target compound 5-bromo-2-methyl-1H-benzo[D]imidazole.
