Procedure

Ethyl 2-(4-nitro-1H-imidazol-1-yl)octanoate (17 moles, 5.0 g) and ethylamine (20 ml) were stirred in 150 ml ethanol at room temperature for 16 hours. The reaction was added to ice water, extracted with ethyl acetate, washed with water, dried over sodium sulfate and concentrated. The oil crystallized upon standing to yield 3.9 g of N-Ethyl-2-(4-nitro-1H-imidazol-1-yl)octanoamide. (MS).
