Versuchsvorschrift

N-[5-fluoro-2-methyl-1-(3,4,5-trimethoxybenzylidene)-3-indenylacetyl]-glycine. Benzyl-N-[5-fluoro-2-methyl-1-(3,4,5-trimethoxy-benzylidene)-3-indenylacetyl]-glycinate (0.03 mol) in a mixture of 25 ml of anhydrous ethanol and 2.5 ml of 1 N sodium hydroxide is allowed to stand at room temperature for 18 h. The solution is diluted with water and extracted with ether. The aqueous layer is acidified with dilute hydrochloric acid and the organic product is extracted with ethyl acetate, washed with water and dried over sodium sulfate. Evaporation of the solution gives N-[5-fluoro-2-methyl-1-(3,4,5-trimethoxybenzylidene)-3-indenylacetic acid, the corresponding indenyl acyl glycine is obtained.
