Reaction Steps

6.80 g (36.7 mmol) of ethyl 4-nitro-1H-imidazole-2-carboxylate are dissolved in 140 ml of acetone, and 11.2 g (80.8 mmol) of potassium carbonate and 4.57 ml (73.5 mmol) of iodomethane are added. The mixture is then stirred at 60° C. for 4 h. According to TLC (cyclohexane/ethyl acetate 2:1), the starting material has been converted completely.
