Versuchsvorschrift

To 949 mg of sodium hydride are added dropwise, under argon, 5 mL of dimethylformamide, followed by addition of a solution of 6.8 g of 3-(1-acetyl-3,3-dimethyl-2,3-dihydro-1H-indol-6-yl)-5,5-dimethylimidazolidine-2,4-dione obtained in stage g) below in 40 mL of dimethylformamide. The solution obtained is stirred for 1.5 hours at 25° C., followed by addition of 5.24 g of 2-chloro-4-chloromethylpyridine obtained in stage b) below. The reaction mixture is stirred at room temperature for 15 hours and diluted with 300 mL of water, and the solid formed is filtered off, washed with three times 20 mL of water and with twice 20 mL of diethyl ether and dried to give 8.8 g of 3-(1-acetyl-3,3-dimethyl-2,3-dihydro-1H-indol-6-yl)-1-[(2-chloropyridin-4-yl)methyl]-5,5-dimethylimidazolidine-2,4-dione in the form of a beige-coloured solid, the characteristics of which are as follows:
