Reaction Steps

A mixture of 1-benzyl-3-bromo-5-hydroxy-2-oxo-1,2-dihydro-[1,7]naphthyridine-6-carboxylic acid methyl ester (80 mg, 0.21 mmol), 4-trifluoromethoxy-phenylboronic acid (64 mg, 0.31 mmol), K3PO4 (87 mg, 0.41 mmol), H2O (7.4 mg, 0.41 mmol), SPhos (4.2 mg, 0.010 mmol) and Pd(OAc)2 (4.2 mg, 0.0062 mmol) in toluene (5 mL) was heated at 100° C. under nitrogen atmosphere for 16 h. After the mixture was cooled to r.t., water (10 mL) and EtOAc (30 mL) were added. 1 M HCl was added with stirring until pH was about 2, and the organic layer was washed with brine, dried over MgSO4, and concentrated. The crude product was purified by silica gel chromatography (5% EtOAc/CH2Cl2) to give 36 mg of the title compound. MS: (+) m/z 471.27 (M+1).
