A suspension of 5-((6-methoxypyridin-3-ylamino)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione (51.3 g, 0.185 mol) in diphenylether (1275 mL) was heated to 250° C. under nitrogen atmosphere for 20 min. The reaction mixture was cooled to RT and diluted with hexane. The gummy solid was then triturated with hexane to obtain 6-methoxy-1,5-naphthyridin-4(1H)-one as a pale brown color solid.
