Versuchsvorschrift

5.0 g of cis-chrysanthemic acid and 0.2 g of azobisisobutyronitrile were dissolved in 50 ml of toluene and thereto was added dropwise a solution of acetyl bromide (55 mg) in toluene with stirring at 80° C. over a period of 20 minutes. Then, the same treatment as in Example 1 was effected to obtain 4.6 g of chrysanthemic acid. The IR spectrum thereof was identical with that of chrysanthemic acid.
