Reaction Steps

A solution of 5-mesityl-2-methyl-4-nitro-1H-imidazole (2.1 g, 8.56 mmol), α-acetyl-γ-butyrolactone (1.21 g, 9.42 mmol), and iron powder (2.39 g, 42.8 mmol) in ethanol (40 mL) and acetic acid (10 mL) was stirred at 80° C. for one day. The mixture was filtered through Celite and evaporated. The resulting crystals were washed with ethyl acetate, to give the title compound (0.95 g) as white crystals.
