2009
Zeitschrift für Kristallographie - New Crystal Structures
Source of material 1-Methyl-1H-imidazole (24.6 g, 0.3 mol) and sodium acetate trihydrate (100 g, 0.7 mol) were dissolved in 350 ml glacial acetic acid and asolution of bromine (143.6 g, 0.9 mol) in 50 ml of glacial acetic acid was added slowly under cooling. The resulting solution was stirred overnight and then poured onto 500 ml of ice water. The precipitate of 2,4,5-tribromo-1-methyl-1H-imidazole was filtered off and recrystallized from aqueous ethanol. Yield: 50.0 g(52 %), mp. 93 °C.
