Reaction Steps

To a solution of 1-methyl-4-nitroimidazole-2-carboxylic acid (2.0 g, 0.012 mol) in dry THF (20 mL) was slowly added oxalyl chloride (6 mL). The solution was heated to reflux for 45 minutes, and the solvent and excess oxalyl chloride were removed under reduced pressure to give 1-methyl-4-nitroimidazole-2-carbonyl chloride as a yellow powder which was coevaporated with dry CH2Cl2 (15 mL).
