실험 절차

A mixture of 1-benzyl-8-bromo-5-hydroxy-2-oxo-3-phenyl-1,2-dihydro-[1,7]naphthyridine-6-carboxylic acid methyl ester (80 mg, 0.17 mmol), 2-ethoxy-5-tributylstannanyl-pyrimidine (107 mg, 0.26 mmol) and PdCl2(PPh3)2 (24 mg, 0.034 mmol) in 4 mL of DMF was heated at 120° C. for 2 h under nitrogen atmosphere. After the mixture was cooled to r.t., EtOAc and brine 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 brine, and dried over MgSO4. After evaporating the solvent in vacuo, the crude product was chromatographed (0-15% EtOAc/CH2Cl2) to give 58 mg of the title compound. MS: (+) m/z 509.44 (M+1).
