Versuchsvorschrift

0.28 ml (1.68 mmol) of diethyl cyanophosphonate is added, dropwise, at 20° C. under argon, to a solution of 0.402 g (1.4 mmol) of 5-fluoro-1-(3-fluorobenzyl)-1H-indole-2-carboxylic acid (example 1.1) and of 0.274 g (1.68 mmol) of 3-amino-6-(pyrrolidin-1-yl)pyridine (WO 02/48152) in 10 ml of dry dimethylformamide. The mixture is stirred for ten minutes and then 0.43 ml (3.08 mmol) of triethylamine is added dropwise. The mixture is stirred at ambient temperature for 18 hours, concentrated under reduced pressure, and then taken up with 50 ml of ethyl acetate. This solution is then successfully washed with three times 20 ml of a saturated sodium hydrogen carbonate solution, 50 ml of water and 20 ml of a saturated sodium chloride solution, and then dried over sodium sulfate, filtered, and concentrated under reduced pressure. The solid obtained is triturated in isopropylether under hot conditions. 0.527 g of a solid is obtained, which solid is dried under reduced pressure.
