Participants

Reaction Steps

To a suspension of N-(4-imidazol-1-yl-2-methyl-6-nitro-phenyl)-acetamide (279 mg, 1.07 mmol) in ethanol (3 mL) was added 2 N HCl (2 mL). The reaction mixture was heated to reflux for 14 h, cooled to room temperature, and neutralized with saturated NaHCO3. The resulting bright orange solid was filtered and dried under vacuum. The title compound (179 mg, 76%) was obtained as an orange solid. 1H NMR (300 MHz, CD3OD) δ 8.78 (1H, s), 8.24 (1H, s), 7.78 (1H, s), 7.64 (1H, s), 7.46 (1H, s), 2.36 (3H, s).
