Procedure

To a solution of Example 3C (3.07 g, 6.03 mmol) in 70 mL 1,2-dimethyoxyethane/ethanol (50:20) was added tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (2.80 g, 9.04 mmol), 2M sodium carbonate (12.06 mL, 24.11 mmol) and bis(triphenylphosphine)palladium(II) dichloride (0.423 g, 0.603 mmol). The mixture was stirred at 100° C. for 3 hours, cooled and diluted with 50 mL ethyl acetate. The organic layer was washed with saturated sodium bicarbonate, water and brine, dried over magnesium sulfate, filtered, and concentrated. Purification by flash chromatography on silica (Analogix 280) eluting with a gradient of 20% to 80% ethyl acetate/hexane gave the title compound. MS (ESI+) m/z 565.43 (M+H)+.
