5-Bromo-N-(naphthalen-2-ylmethyl)pyrazin-2-amine (0.2 g, 0.637 mmol), L-p-boronophenylalanine (0.13 g, 0.637 mmol), palladiumtriphenylphosphine dichloride (13 mg, 0.019 mmol), Na2CO3 (0.13 g, 1.27 mmol), acetonitrile (5 mls) and water (5 mls) were heated in a microwave reactor at 150° C. for 5 minutes. The mixture was concentrated, dissolved in 1.0 N HCl, washed twice with ether, concentrated, dissolved in methanol, filtered and concentrated to yield 0.12 g of the captioned compound.
