실험 절차

330 mg (1.10 mmol) of 4-[(3-cyclopropyl-1H-pyrrolo[2,3-b]pyridin-4-yl)oxy]-3,5-difluoroaniline and 320 mg (1.64 mmol) of 4-chloro-6-(trifluoromethyl)pyrimidine-2-amine are suspended in 4 ml of water and 2 ml of ethanol. 0.55 ml (2.2 mmol) of 4N hydrochloric acid is added, and the mixture is heated at reflux for 1 h. Another 107 mg (0.55 mmol) of 4-chloro-6-(trifluoromethyl)pyrimidine-2-amine are then added, and the mixture is heated for a further 2 hours. The mixture is made alkaline by addition of 1N aqueous sodium hydroxide solution and extracted with ethyl acetate, and the organic phase is washed with water. The organic phase is dried over sodium sulfate and the solvent is removed under reduced pressure. The product is purified by preparative HPLC.
