Reaction Steps

4-[2-(Pteridin-4-ylamino)-ethyl]-phenol (0.27 g, 1.0 mmol), 2,3,5,6-tetrafluoro-4-trifluoromethylpyridine (0.24 g, 1.0 mmol) and DMF (5 mL) were added to a 25 mL round bottom flask equipped with magnetic stirring bar and dry nitrogen line. To the reaction mixture was added Et3N (0.12 g, 1.2 mmol). After stirring 24 h at room temperature, the reaction mixture was concentrated in vacuo, and the residue was partitioned between H2O and EtOAc. The organic layer was concentrated in vacuo and the residue was purified by column chromatography (EtOAc/hexane over SiO2) to afford pteridin-4-yl-{2-[4-(3,5,6-trifluoro-4-trifluoromethyl-pyridin-2-yloxy)-phenyl]-ethyl}-amine (110 mg) as a beige solid: mp 103-108° C.
