Versuchsvorschrift

479 Milligrams of 2-(4-chlorobenzoylamino)-3-(oxindol-3-yl)propionic acid 1/4-hydrate prepared in Example 3 and 70 mg of 50% sodium hydride (in oil) were admixed in 5 ml of dimethylformamide, and the mixture was stirred at a room temperature for 1 hour. Then a solution containing 0.23 g of methyl iodide in 3 ml of dimethylformamide was added dropwise gradually to the mixture, and the whole reaction mixture was stirred at a room temperature for 4 hours. The reaction mixture was poured into a large volume of water, and the organic material was extracted with chloroform, then the chloroform layer was washed with water and dried. Chloroform was removed by evaporation to yield 125 mg of 2-(4-chlorobenzoylamino)-3-(1-methyloxindol-3-yl)propionic acid.
