Procedure

To as solution of Example 369B (20 g, 41.9 mmol), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (16.85 g, 54.5 mmol), and tetrakis(triphenylphosphine)palladium (4.84 g, 4.19 mmol) in N,N-dimethylformamide (500 mL) was added a solution of sodium bicarbonate (7.04 g, 84 mmol) in water (40 mL) and the mixture was stirred at 80° C. for 12 hours. The reaction was quenched by the addition of saturated aqueous sodium thiosulfate, water and ethyl acetate. The aqueous layer was extracted with ethyl acetate and the combined organics were dried over sodium sulfate, filtered and concentrated to provide the title compound. MS (CI) m/z 532 (M+H)+.
