Reaction Steps

(Some starting materials may be obtained from AstaTech, Inc. Princeton, N.J.) A 15 mL sealed pressure tube was charged with N-(5-bromo-2-chloropyridin-3-yl)-4-methoxybenzenesulfonamide (120 mg, 0.318 mmol), 6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinoline (90 mg, 0.350 mmol) in ethanol (1.5 mL). To this was added 5 mol % of Pd(PPh3)4 (18 mg, 0.016 mmol) and Na2CO3 (2M, 0.4 mL). The flask was flushed with argon, sealed and stirred at 90° C. for 4 hours. The crude mixture was partitioned between water and ethyl acetate, extracted with ethyl acetate (3×), dried over Na2SO4 and concentrated in vacuo. The Solids were taken up in minimal methylene chloride and purified via ISCO, 40 g RediSep® (Teledyne ISCO, Lincoln, Nebr.) column with a 20-100% gradient of ethyl acetate in hexanes, to afford the desired material.
