Experimental conditions analogous to those described for Step 2 of Example 1 were used with 0.59 g (1.82 mmol) of 2-(3,4-Dimethyl-benzoyl)-3-(6-methyl-pyridin-2-ylamino)-acrylic acid methyl ester in 30 mL of diphenyl ether to yield 0.33 g of 3-(3,4-Dimethyl-benzoyl)-7-methyl-1H-[1,8]naphthyridin-4-one as a brown solid.
