Versuchsvorschrift
4.0 g (18.2 mmol) of 4-hydrazino-3-trifluoromethylbenzoic acid is dissolved in 20 mL of glacial acetic acid, combined with 3.3 g (18.2 mmol) of ethyl oxo-(2-oxocyclopentyl)acetate, and refluxed for 2 hours under a nitrogen atmosphere. After cooling, it is stirred with diethyl ether and the precipitate is suction filtered. Yield: 2.9 g (43%).
