Reaction Steps

To a solution of N-[1-butyl-4-{3-(3-bromo-1-propynyl)phenyl}-1,2-dihydro-2-oxo-1,8-naphthyridin-3-yl]-N'-(2,6-diisopropylphenyl)urea (400 mg, 0.65 mmol) in THF (5 ml) was added pyrrolidine (139 mg, 1.96 mmol), and the mixture was stirred at room temperature for four hours. To the mixture was added water, and the mixture was extracted with ethyl acetate. The extract was washed with water, 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 chromatography (ethyl acetate) to give the title compound (340 mg, 0.56 mmol).
