Experimental conditions analogous to those described for Step 1 of Example 1 were used with 0.60 g (2.27 mmol) of 3-ethoxy-2-(4-methoxy-3-methyl-benzoyl)-acrylic acid methyl ester, 0.214 g (2.27 mmol) of 3-aminopyridine, and 15 mL of diphenyl ether to yield 0.435 g of 3-(4-Methoxy-3-methyl-benzoyl)-1H-[1,5]naphthyridin-4-one.
