4-BROMO-1-METHYL-1H-IMIDAZOLE

To a solution of N-methylimidazole (1.64 g, 19.97 mmol) and sodium acetate (25 g, 300 mmol) in acetic acid (180 mL) at room temperature was added bromine (9.6 g, 60.07 mmol) dropwise as a solution in 20 mL acetic acid. The resulting mixture was stirred for 2.5 h at room temperature. Acetic acid was removed in vacuo, the residue was suspended in 500 mL water and stirred at room temperature for 10 minutes. The resultant precipitate was filtered, washed with water and dried under high vacuum to give 2, 4, 5-tribromo-l-methyl- lH-imidazole (1.82 g, 29percent - some product remained in the mother liquor) as a light yellow powder. Used without further characterization. To a suspension of the tribromide (1.82 g, 5.71 mmol) in 45 mL water was added sodium sulfite (13 g, 103 mmol) and the resulting mixture was stirred at rapid reflux for 24 h. After cooling to room temperature, organics were extracted with ether (3
