Procedure

To a solution of methyl 5-{[[(4-bromophenyl)sulfonyl](hexyl)amino]methyl}-2-fluorobenzoate (96 mg; 0.20 mmol) in DMF (5 mL) were added (Aldrich, p-butylphenylacetylene (31 mg; 0.20 mmol), bis(triphenylphosphine) palladium (II) chloride (6.9 mg; 0.01 mmol), copper(I) iodide (1.9 mg; 0.01 mmol), triphenylphosphine (10.4 mg; 0.04 mmol) and TEA (0.08 mL; 0.59 mmol). The mixture was stirred for 1500 s at 150° C. under MW. The mixture was diluted with Et2O (50 mL) and the precipitate obtained filtrated off. Filtrate was washed with HCl 1N and with brine (75 mL). The organic layer was dried over magnesium sulfate and the solvent was removed under reduced pressure. Purification by flash chromatography using silicagel (c-Hex:EtOAc, 9:1 then 1:1) gave 66 mg (63.3%) of the title compound as a white solid. HPLC: Rt=6.12 min (purity=99.6%). LC/MS: M+(ESI): 564.4. 1H NMR (CDCl3) δ: 7.79 (d, J=8.3 Hz, 3H) 7.64 (d, J=8.7 Hz, 2H), 7.56 (m, 1H), 7.46 (d, J=8.3 Hz, 2H), 7.19 (d, J=7.9 Hz, 2H), 7.15 (s, 1H), 4.33 (s, 2H), 3.92 (s, 3H), 3.11 (t, J=7.5 Hz, 2H), 2.63 (t, J=7.7 Hz, 2H), 1.61 (t, J=7.7 Hz, 2H), 1.35 (m, 5H), 1.15 (m, 5H), 0.93 (t, J=7.3 Hz, 3H), 0.81 (t, J=6.9 Hz, 3H).
