Reaction Steps

A suspension of 18.6 g of 4-fluorobenzaldehyde and 18.6 g of 4-nitroimidazole in 70 ml of dimethylformamide was dropwise added to a suspension of 6.6 g of sodium hydride (60% suspension in mineral oil) in 150 ml of dimethylformamide at a room temperature under stirring. The obtained mixture was stirred at 90° C. for about 5 hours, cooled and poured into ice-water to precipitate a solid. This solid was recovered by filtration, washed with water and heated together with ethanol. The mixture was cooled and filtered. The obtained solid was washed with ethanol to obtain 18 g of the title compound as a white powder (yield: 55%).
