Reaction Steps

A mixture of 3-bromo-5-hydroxy-2-oxo-1-phenethyl-1,2-dihydro-[1,7]naphthyridine-6-carboxylic acid methyl ester (166 mg, 0.41 mmol), PhSnBu3 (0.16 mL, 0.49 mmol), and PdCl2(PPh3)2 (58 mg, 0.082 mmol) in DMF (4 mL) was heated at 120° C. under nitrogen atmosphere for 2 h. After the mixture was cooled to r.t., brine (10 mL) and EtOAc (50 mL) were added. The aqueous layer was extracted with additional EtOAc and the organic layers were combined, washed with water, and dried over MgSO4. After evaporating the solvent in vacuo, the crude product was chromatographed (0-40% EtOAc/hexanes+2% AcOH) to give 151 mg of the title compound as a light yellow solid. MS: (+) m/z 401.30 (M+1).
