Procedure

2-Bromopropane (7 mmol) and K2CO3 (13 mmol) were added to a solution of 2-nitroimidazole (4 mmol) in DMF (10 mL). The mixture was stirred at 60° C. for 4 h. The contents were cooled to room temperature and water (20 mL) was added and the mixture was extracted with EtOAc (3×10 mL). The combined extracts were dried over MgSO4, filtered and the solvent was removed in vacuo to afford 1-isopropyl-2-nitro-1H-imidazole. The product used for further transformation without further purification.
