Procedure

82 mg (0.31 mmol) of 4-(4-amino-2-fluorobenzyl)-1H-pyrrolo[2,3-b]pyridine-3-carbonitrile and 67 mg (0.34 mmol) of 4-chloro-6-trifluoromethylpyrimidine-2-amine are suspended in 3 ml of water, 1.5 ml of ethanol and 0.15 ml of 4N hydrochloric acid. The reaction mixture is heated at reflux for 2 hours. After cooling, the mixture is made alkaline using dilute aqueous sodium hydroxide solution, a little methanol is added, the mixture is extracted with ethyl acetate and the solvent is removed under reduced pressure. The residue is purified by preparative HPLC. This gives crystals.
