To a pressure vessel was added 2-(dicyclohexylphosphino)biphenyl (12 mg, 0.42 mmol), 6-(1-(5-bromoisoxazolo[5,4-b]pyridin-3-yl)ethyl)quinoline (0.10 g, 0.28 mmol), 4-(tributylstannyl)thiazole (0.16 g, 0.42 mmol) in anhydrous DMF (3 mL). The vial was flushed with argon, sealed and stirred at 90° C. for two hours. The mixture was concentrated and purified by MPLC (eluted with a gradient of 0 to 10% methanol in dichloromethane) to yield the racemic product as an off-white solid. The desired enantiomer (>99% cc) was obtained via SFC. MS m/z=359.0 [M+1]+ Calc'd for C20H14N4OS: 358.4
