実験手順

To a solution of 5-[({4-bromophenyl)sulfonyl](hexyl)amino]-2-fluorobenzoate (400 mg; 0.85 mmol) in DMF (15 mL) under nitrogen were added (p-butylphenyl)acetylene (0.16 mL; 0.93 mmol), bis(triphenylphosphine)palladium chloride (29.7 mg; 0.04 mmol), triphenylphosphine (44.4 mg; 0.17 mmol), copper iodine (8.1 mg; 0.04 mmol) and TEA (0.35 mL; 2.54 mmol). The reaction mixture was stirred under MW at 120° C. for 1500 s. The mixture was diluted with Et2O (75 mL) and the precipitate obtained filtrated off. Filtrate was washed with HCl 1N and with brine. The organic layer was dried over magnesium sulfate and the solvent was removed under reduced pressure. Purification by flash chromatography on silicagel (c-Hex/EtOAc, 95:5 then 90:10) gave 207 mg (44.5%) of the title compound as a yellow cream. HPLC, Rt: 6.17 min (purity=98.5%). LC/MS: M+(ESI): 500.3, 1H NMR (CDCl3) δ: 7.55 (m, 6H), 7.32 (m, 1H), 7.10 (m, 4H), 3.91 (s, 3H), 3.52 (t, J=6.9 Hz, 2H), 2.63 (t, J=7.9 Hz, 2H), 1.30 (m, 12H), 0.95 (m, 3H), 0.85 (t, 3H.
