Reaction Steps

To a solution of N-[1-butyl-4-{3-(3-hydroxy-1-propynyl)phenyl}-1,2-dihydro-2-oxo-1,8-naphthyridin-3-yl]-N'-(2,6-diisopropylphenyl)urea (90 mg, 0.16 mmol) in methylene chloride (1.5 ml) were added carbon tetrabromide (81 mg, 0.245 mmol) and triphenylphosphine (51 mg, 0.196 mmol) under ice-cooling, and the mixture was stirred for 30 minutes. To the mixture was added water, and the mixture was extracted with ethyl acetate. The extract was washed with a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane: 1:5) to give the title compound (53 mg, 0.086 mmol).
