This compound was prepared, starting from compound 106 (206 mg, 0.50 mmol), according to the procedure developed for compound 112. The purification was performed using column chromatography (Al2O3, cyclohexane/AcOEt, 5/5, v/v) to give compound 113 (165 mg, 0.29 mmol) as an orange oil. Yield 57%; Rf (Al2O3, cyclohexane/AcOEt, 5/5, v/v) 0.73; IR (CCl4) ν 1521, 1684, 2929, 2962 cm−1; 1H NMR (200 MHz, CDCl3) δ 0.88 (t, 9H, J=7.0 Hz), 1.10 (t, 6H, J=7.1 Hz), 1.17 (m, 6H), 1.33 (m, 6H), 1.55 (m, 6H), 2.64 (q, 4H, J=7.1 Hz), 2.74 (t, 2H, J=6.3 Hz), 3.59 (q, 2H, J=6.3 Hz), 7.88 (d, 1H, J=8.3 Hz), 7.94 (d, 1H, 3JH-F=10.4 Hz), 8.04 (dd, 1H, J=1.4, 8.3 Hz), 8.20 (d, 1H, 3J119Sn/117Sn-H=40.8 Hz), 8.61 (m, 1H); ESI-MS m/z 580.2 [M+H]+.
