Versuchsvorschrift

120 mg (0.45 mmol) of 4-(4-amino-2-fluorobenzyl)-1H-pyrrolo[2,3-b]pyridine-3-carbonitrile and 64 mg (0.50 mmol) of 4-chloropyrimidine-2-amine are suspended in 4 ml of water, 2 ml of ethanol and 0.23 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.
