実験手順

To a stirred solution of 3-dimethylamino-2-(3-fluoro-pyridine-2-carbonyl)acrylic acid ethyl ester (4) (18 mg, 0.067 mmol) in dimethylacetamide (2 mL) was added K3PO4 (28 mg, 0.14 mmol) followed by C-biphenyl-2-yl-methylamine (5) (11 mg, 0.06 mmol) at room temperature. The mixture was stirred at 70° C. for 14 h. After completion of the reaction, the reaction mixture was poured into ice water and extracted with ethyl acetate. The organic layer was washed with brine, dried over Na2SO4 and concentrated. The residue was purified using normal silica gel column chromatography (3% methanol:dichloromethane) to get 1-biphenyl-2-ylmethyl-4-oxo-1,4-dihydro-[1,5]naphthyridine-3-carboxylic acid ethyl ester (6) (9 mg, 35%) as a sticky solid.
