Reaction Steps

To a solution of N-[4-(3-methoxyphenyl)-1,2-dihydro-2-oxo-1,8-naphthyridin-3-yl]-N'-(2,6-diisopropylphenyl)urea (200 mg, 0.43 mmol) and N-(3-bromopropyl)phthalimide (133 mg, 0.50 mmol) in DMF (10 ml) was added potassium carbonate (114 mg, 0.83 mmol), and the mixture was stirred at 50°-60° C. for one hour. After allowed to stand for cooling, the mixture was poured into water, and the mixture was 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 residue was concentrated under reduced pressure, purified by silica gel column chromatography (1-3% methanol in chloroform), and crystallized from hexane to give the title compound (229 mg, 0.35 mmol).
