8-Chloro-[1,7]naphthyridine (Example A) (0.2 g, 1.2 mmol) and 2-amino-6-methylpyridine (0.13 g, 1.2 mmol) were dissolved in 8 ml dry dioxane. 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (145 mg, 0.24 mmol), cesium carbonate (0.63 g, 1.95 mmol) and tri(dibenzylideneacetone)dipalladium chloroform complex (0.13 g, 0.12 mmol) were added and the reaction mixture was stirred under microwave irradiation for 50 minutes at 150° C. The reaction mixture was then evaporated and purified by flash chromatography on silica gel (heptane/ethyl acetate 95:5->70:30 gradient). The desired product was obtained as a light yellow solid (98 mg, 34%),
