Procedure

32 mg (0.11 mmol) of 3-fluoro-4-(1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)aniline and 26 mg (0.12 mmol) of 4-chloro-6-(trifluoromethyl)pyrimidine-2-amine are suspended in 5 ml of water and 0.07 ml of 2N hydrochloric acid. The reaction mixture is heated at reflux for 20 hours. After cooling, the mixture is made alkaline using dilute aqueous sodium hydroxide solution, a little methanol is added and the mixture is extracted with ethyl acetate. The extract is dried over sodium sulfate and the solvent is removed under reduced pressure. The residue is purified by preparative HPLC.
