Reaction Steps

250 mg (0.65 mmol) of 4-(4-amino-2,6-difluorophenoxy)-1H-pyrrolo[2,3-b]pyridine-3-carbonitrile and 92 mg (0.71 mmol) of 4-chloropyrimidine-2-amine are suspended in 10 ml of water and 5 ml of ethanol. 0.32 ml (1.29 mmol) of 4N hydrochloric acid is added, and the mixture is heated at reflux for 2 h. The mixture is made alkaline using concentrated aqueous sodium hydroxide solution, diluted with water and extracted with ethyl acetate. The organic phase is separated off and concentrated. The crude product is purified by preparative HPLC. This gives the title compound as crystals.
