Hydrogen Bromide → HCID 67259836, compound

Participants

Reaction Steps

To a solution of 4-(2-methyl-1H-imidazol-1-yl)aniline (10 g, 57.8 mmol) in 100 mL of HBr solution was added a solution of NaNO2 (5.2 g, 75.1 mmol) in H2O (60 mL) at 0° C. Stirred at this temperature for 20 min., then poured the mixture into a solution of CuBr (58 g, 404 mmol) in HBr solution (200 mL) at 0° C., and stirred for 30 min., diluted with water, and stirred at room temperature for 1 hour. The precipitate was separated out, and evaporated in vacuo to give 28 g of crude product, which was purified by Prep-HPLC to obtain 1-(4-bromophenyl)-2-methyl-1H-imidazole (7 g, yield 51%).
