Procedure

To a solution of N-[1-butyl-4-{3-(2-propynyloxy)phenyl}-1,2-dihydro-2-oxo-1,8-naphthyridin-3-yl]-N'-(2,6-diisopropylphenyl)urea (1.0 g, 1.82 mmol) in dioxane (10 ml) were added paraformaldehyde (0.37 g), diethylamine (0.26 g, 3.63 mmol) and copper (I) iodide, and the mixture was stirred at room temperature for two hours. To the mixture was added ether, and the mixture was filtered through a cerite pad. The filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (2% methanol in chloroform) to give the title compound (1.05 g, 1.65 mmol).
