Versuchsvorschrift

A solution of 1-(4-chlorophenyl)cyclopropanecarboxylic acid (5.0 g, 25.3 mmol), 2-(4-methoxyphenyl)ethanamine (4.2 g, 28 mmol) and 4-N,N-Dimethylaminopyridin (3.3 g; 28 mmol) in methylenehloride (200 ml) was cooled to −10′C. N-ethyl-N′-(3-Dimethylaminopropyl)-carbodiimid hydrochloride (EDC, 5.3 g, 28 mmol) was added in several portions and the resulting mixture stirred overnight. The reaction mixture was poured into water and consecutively extracted with water, 2N NaOH and 1N HCl. Evaporation of the dried (NaSO4) extract yielded an oily residue that crystallized upon addition of n-heptan, which was used without further purification. Yield 7.0 g (21.2 mmol, 83%).
