Reaction Steps
53 mg (0.18 mmol) of 3-fluoro-4-{[3-(2-methoxyethyl)-1H-pyrrolo[2,3-b]pyridin-4-yl]oxy}aniline and 42 mg (0.21 mmol) of 4-chloro-6-(trifluoromethyl)pyrimidine-2-amine are suspended in 4 ml of water. 0.23 ml (0.23 mmol) of 1N hydrochloric acid is added, and the mixture is heated at reflux overnight. Another 22 mg (0.11 mmol) of 4-chloro-6-trifluoromethyl)pyridine-2-amine are then added, and the mixture is again heated overnight. 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 washed with water. The product is purified by preparative HPLC.
