実験手順

A mixture of 1-benzyl-8-bromo-5-hydroxy-2-oxo-3-(4-trifluoromethyl-phenyl)-1,2-dihydro-[1,7]naphthyridine-6-carboxylic acid methyl ester (76 mg, 0.14 mmol), 3-tributylstannanyl-pyridine (0.068 mL, 0.21 mmol) and PdCl2(PPh3)2 (20 mg, 0.029 mmol) in 4 mL of DMF was heated at 120° C. for 2.5 h under nitrogen atmosphere. After the mixture was cooled to r.t., EtOAc and water were added. 1 M HCl was added with stirring until pH was about 3-4. The aqueous layer was extracted with additional EtOAc, and the combined organic layer was washed with water and dried over MgSO4. After evaporating the solvent in vacuo, the crude product was purified by silica gel chromatography (5-100% EtOAc/hexanes+1% AcOH) to give 32 mg of the title compound as a tan solid. MS: (+) m/z 532.30 (M+1).
