Experimental conditions analogous to those described for Step 1 of Example 1 were used with 0.50 g (1.88 mmol) of 3-ethoxy-2-(4-methoxy-3-methyl-benzoyl)-acrylic acid methyl ester, 0.20 g (1.88 mmol) of 6-Methyl-pyridin-3-ylamine, and 10 mL of diphenyl ether to yield 0.33 g of 3-(4-Methoxy-3-methyl-benzoyl)-6-methyl-1H-[1,5]naphthyridin-4-one.
