Procedure

0.67 g of sebacic acid, 1.0 ml of triethylamine and 2 ml of phosphorus oxychloride with 40 ml of methylene chloride were added and stirred at 0° C. for 30 minutes, and then 60 ml of pyrophosphoric acid and 6.0 g of ferrocene were added, and the resulting mixture was heat-refluxed. Subsequently, the same procedure as in Example 7 was conducted, to obtain a ferrocenoylnonanoic acid in an amount of 2.22 g and in a yield of 60.0%.
