実験手順

A mixture of N-(8-indol-1-yl-octyl)-3,5-diiodo-4-hydroxybenzamide (4.016 g, 6.517 mmol), 2 M K2CO3 (9.8 ml in water), dioxane (100 ml), 3-chlorophenylboronic acid (2.242 g, 14.336 mmol), and [1,1′bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with CH2Cl2 (0.106 g, 0.130 mmol) was warmed to 66° C. After 2 h, the reaction mixture was cooled and concentrated in vac. The residue was taken up in EtOAc (200 ml) and 1N HCl (50 ml). The layers were shaken, separated and the organic layer was washed with 1N HCl (2×50 ml), brine (2×50 ml), dried over Na2SO4, filtered and the filtrate concentrated in vac and dried. The crude product was purified by flash chromatography (alumina, hexane to 60% EtOAc/Hex gradient) to give a light yellow foam (3.027 g, 79%); 1H NMR (300 MHz, DMSO-d6) δ 1.24 (broad s, 8H), 1.43-1.52 (m, 2H), 1.65-1.75 (m, 2H), 3.16-3.26 (q, J=7.5 Hz, 2H), 4.12 (t, J=7.5 Hz, 2H) 6.38 (d, J=3 Hz, 1H), 6.94-7.00 (m, 1H), 7.05-7.13 (m, 1H), 7.33 (d, J=3 Hz, 1H), 7.40-7.53 (m, 8H), 7.62 (s, 2H), 7.76 (s, 2H), 8.40 (t, J=5 Hz, 1H), 9.19 (s, 1H); mass spectrum [(+)ESI], m/z 585 (M+H)+.
