5-Bromo-3-(1-ethyl-1H-imidazo[4,5-c]pyridin-2-yl)pyrazin-2-amine (0.051 g, 0.16 mmol) (made in example 2), 4-ethynylaniline (0.060 g, 0.51 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.006 g, 0.009 mmol), copper iodide (0.004 g, 0.02 mmol) and triethyl amine (3 mL) were combined and subjected to 180° C. for 1 hr in a SmithSynthesizer microwave. The resulting mixture is treated with silica gel, and the volatiles removed in vacuo. The title compound is obtained by silica gel chromatography (0.004 g).
