Procedure

To a solution of N-[1-butyl-4-{3-(2-hydroxyethoxy)phenyl}-1,2-dihydro-2-oxo-1,8-naphthyridin-3-yl]-N'-(2,6-diisopropylphenyl)urea (2.02 g, 3.63 mmol) in THF (20 ml) were added p-toluenesulfonyl chloride (0.69 g, 3.63 mmol) and triethylamine (0.40 g, 3.99 mmol), and the mixture was stirred at 40°-50° C. for 8 hours. The mixture was poured into water, and extracted with ethyl acetate. The extract was washed with water, washed with a saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The resultant was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:1) to give the title compound (1.40 g, 1.97 mmol).
