Procedure
The procedure of Synthetic Example 1 was repeated using a mixture of 4-hydroxy-1-(3-nitrophenyl)-1,8-naphthyridin-2 (1H)-one (2.5 g, 8.83 mmol), 3-(pyridin-4-yl)propionic acid (19.87 g, 131 mmol, 15 eq.; prepared in Synthetic Example 1-(1)) and polyphosphoric acid (about 100 ml) to obtain 4-hydroxy-1-(3-nitrophenyl)-3-[1-oxo-3-(pyridin-4-yl)propyl]-1,8-naphthyridin-2 (1H)-one (1.98 g, 54%).
