Versuchsvorschrift

A solution of 3.12 g (0.1 mole) of 2-amino-3-benzoyl-5-chlorobenzeneacetic acid, sodium salt.1/2 H2O in 250 ml of dry dimethylformamide was treated with 44 g of ethyl iodide (0.3 mole) under nitrogen and stirred for 2 hours. The resulting solution was then added to one liter of water and extracted several times with ethyl ether. The combined ether layers were washed with water, dried over sodium sulfate, filtered and stripped to yield a solid yellow residue. This residue was recrystallized from ethyl alcohol, yielding 1.5 g of the title compound as yellow needles, m.p. 80°-82° C.
