Procedure

11.2 g of 2-ethoxy-3-[1-(2-chlorophenyl)-1-cyclopropyl]-acrylic acid is stirred in 230 ml of 1 M sulfuric acid and 42 ml of concentrated acetic acid for 24 hours at 110° C. Water is added, it is extracted with ethyl acetate, and ethyl acetate solution is washed with water. After drying (Na2SO4) and concentration by evaporation, 10.7 g of the product is obtained.
