Reaction Steps

To a glass microwave vial was added 4-(3-chloropyrazin-2-yloxy)aniline (1.0591 g, 4.78 mmol), 2-methoxy-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine hydrate, trans-dichlorobis(triphenylphosphine) palladium (II) (0.268 g, 0.382 mmol), and sodium carbonate (2.53 g, 23.89 mmol) in DME (7.65 mL) and water (1.911 mL). The reaction mixture was stirred and heated in a Biotage Initiator microwave reactor at 100° C. for 15 min. The crude product was adsorbed onto a plug of silica gel and chromatographed to provide 4(3-(2-methoxypyridin-3-yl)pyrazin-2-yloxy)aniline. MS (ESI, pos. ion) m/z:295.2.
