Procedure
To a solution of N-[4-(3-methoxyphenyl)-1,2-dihydro-2-oxo-1,8-naphthyridin-3-yl]-N′-[2-tert-butyl-5-(morpholinomethyl)phenyl]urea (300 mg, 0.55 mmol) in DMF (10 ml) are added successively potassium carbonate (91.8 mg, 0.66 mmol), potassium iodide (18.4 mg, 0.11 mmol) and 1-iodohexane (117 mg, 0.55 mmol), and the mixture is stirred at room temperature for one hour, and stirred at 40-50° C. for 4 hours. The reaction solution is poured into water, and the mixture is extracted with ethyl acetate. The extract is washed with water and a saturated brine, and dried over anhydrous magnesium sulfate. The solvent is concentrated under reduced pressure, and the resulting residue is purified by silica gel column chromatography (chloroform→3% methanol/chloroform) to give the title compound (290 mg, 0.47 mmol) as colorless oil.
