Versuchsvorschrift

2-(4-Nitro-1H-imidazol-1-yl)octanoic acid (7.8 mmoles,2.0 g) was treated with 25 ml oxalyl chloride, concentrated and added to a solution of trifluoroethylamine hydrochloride (7.8 mmoles, 1.06 g) and triethylamine (2 ml) in 50 ml THF. After stirring at room temperature for 16 hours, the mixture was added to ice, extracted with ethyl acetate, dried over sodium sulfate, and concentrated. The intermediate was chromatographed over silica gel to yield 0.6 g of N-(2,2,2-trifluoro)ethyl-2-(4-nitro-1H-imidazol-1-yl)octanoamide. (MS).
