Procedure
To a solution of prop-2-enyl 3-[(3-{4-[(methylsulfonyl)amino]phenyl}-4-oxochromen-7-yloxy)methyl]benzoate (88.8 mg, 0.176 mmol), tetrakis(triphenyl-phosphine)palladium(0) (10 mg, 0.009 mmol) in dry tetrahydrofuran 2 ml) was added morpholine (77 mg, 0.88 mmol), and the mixture was stirred at room temperature under argon for 2 hours. Solvent was then removed reduced pressure, and the residue dissolved in acetone, mixed with silica gel, the solvent removed under reduced pressure, and the silica gel eluted with methylene chloride/methanol (95/5) containing 1% acetic acid, to provide 3-[(3-{4-[(methylsulfonyl)amino]phenyl}-4-oxochromen-7-yloxy)methyl]benzoic acid; 1H NMR (400 MHz, DMSO-d6) δ: 13.1 (br s, 1H), 9.84 (s, 1H), 8.47 (s, 1H), 8.08-8.06 (m, 2H), 7.94 (d, 1H, J=7.8 Hz), 7.76 (d, 1H, J=7.7 Hz), 7.58-7.45 (m, 3H), 7.30 (d, 1H, J=1.8 Hz), 7.27 (d, 2H, J=8.5 Hz), 7.20 (dd, 1H, J=1.8 Hz, J=8.9 Hz), 5.38 (s, 2H), 3.03 (s, 3H). (ESI) m/z 466 (M+H)+.
