Participants

Reaction Steps

3.19 g of furan-2-carboxylic acid (3-iodo-phenyl)-amide (Example 13bf)) are dissolved in 25 ml of methylene chloride with 2.78 ml of triethylamine and 100 mg of 4-dimethylaminopyridine. 1.60 g of cyclopropanecarbonyl chloride are added thereto and the mixture is stirred at room temperature for 5 hrs. The mixture is concentrated, poured into water and extracted three times with ethyl acetate. Chromatography on silica gel with ethyl acetate/hexane 3:7 gives 1.56 g of cyclopropanecarboxylic acid (furan-2-carbonyl)-(3-iodo-phenyl)-amide as a colourless solid. Yield: 58%. Mass spectrum: peaks inter alia at m/e: 381 (20%), 353 (28%), 313 (86%), 95 (75%), 69 (100%).
