実験手順

{4′-Bromo-2′-[(cyclopropanecarbonyl-ethyl-amino)-methyl]-6-methoxy-biphenyl-3-yl}-acetic acid ethyl ester (14.5 g, 30.6 mmol) was dissolved in DME (100 mL) and water (50 mL) along with 2-ethoxy-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridine (9.1 g, 36.5 mmol) and potassium carbonate (10.7 g, 77.4 mmol) under N2 atmosphere. The mixture was purged with N2, and then tetrakis(triphenylphosphine)palladium(0) (0.500 g, 0.43 mmol) was added and the reaction was heated to 80° C. The reaction was monitored by analytical LCMS and when the starting material was consumed, the mixture was cooled to room temperature and diluted with ethyl acetate and water. The aqueous layer was separated and extracted with ethyl acetate, and the combined organic layers were dried over magnesium sulfate, filtered, and concentrated. The residue was purified by silica gel chromatography (0-35% ethyl acetate in hexanes) to afford the title compound.
