---|---|---|
With N-Bromosuccinimide; In dichloromethane; at 0℃; for 2h; | A mixture of 1,2-dimethyl-1H-imidazole (2.80 g, 29.1 mmol) and NBS (5.40 g, 30.3 mmol) in dichloromethane (100 mL) was stirred for 2 hours at 0 C. and diluted with 100 mL of dichloromethane. The mixture was washed with 3×200 mL of H2O, dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum. The residue was purified by flash column chromatography (silica gel column, 10:1 CH2Cl2/MeOH) to give the title compound as a pink solid. | |
3.78 g | With N-Bromosuccinimide; In N,N-dimethyl-formamide; at 25℃; for 3h;Inert atmosphere; | To a solution of 1,2-dimethyl-1H-imidazole (1a) (96 mg, 1 mmol) in DMF (5 mL), was added NBS (169 mg, 0,95 mmol) and the resulting reaction mixture was stirred in the dark at room temperature for 3 h. The orange-yellowish solution thus obtained was diluted with EtOAc (50 mL), washed with a 10% aqueous solution of NaOH (2 x 50 mL), water (50 mL) and brine (50 mL). The aqueous phases were back-extracted with EtOAc (50 mL) and the combined organic phases dried over Na2SO4 and filtered. The solvent was removed at reduced pressure, affording the title compound as colorless crystals (3.78 g, 76%). |
