Versuchsvorschrift

114 mg (0.40 mmol) of 4-[(3-cyclopropyl-1H-pyrrolo[2,3-b]pyridin-4-yl)oxy]-3-fluoroaniline and 95 mg (0.48 mmol) of 4-chloro-6-(trifluoromethyl)pyrimidine-2-amine are suspended in 3.5 ml of water. 0.52 ml (0.52 mmol) of 1N hydrochloric acid are added, and the mixture is heated at reflux overnight. Another 30 mg (0.15 mmol) of 4-chloro-6-(trifluoromethyl)pyrimidine-2-amine are then added, and the mixture is heated for another 6 hours. By addition of 1N aqueous sodium hydroxide solution, the pH is adjusted to 10, resulting in the precipitation of crystals. The crystals are filtered off with suction and purified by chromatography on silica gel (mobile phase: dichloromethane/methanol (7N ammonia) 100:1 to 100:3).
