Versuchsvorschrift

4.38 g 1-acetyl-2-indolinone, 3.41 g pyrazine-2-carboxylic acid, 8.83 g TBTU, 4.21 g HOBT-hydrate and 21.8 ml ethyldiisopropylamine are stirred in 70 ml DMF for 15 hours at ambient temperature. The mixture is poured onto 400 ml ice water and 10 ml of conc. hydrochloric acid and stirred for 1 hour. The precipitate is suction filtered, washed with water, stirred with methanol, suction filtered again, washed with methanol and dried at 100° C.
