실험 절차

To a stirred solution of N-(8-indol-1-yl-octyl)-3,5-bis(3-chlorophenyl)-4-(2-hydroxyethoxy)benzamide (0.629 g, 1 mmol) in THF (10 ml) under nitrogen at room temperature was sodium hydride (0.055 g, 2.3 mmol). The mixture was refluxed for 45 minutes, cooled and methylbromoacetate (0.189 g, 1.2 mmol), 15-crown-5 ether (0.022 g, 0.1 mmol), and tetrabutylammoniumiodide (0.037 g, 0.1 mmol) were added. The mixture was refluxed. After 6 h, the reaction mixture was quenched with water and then diluted with water (100 ml) and extracted with EtOAc. This gave a thick emulsion which was separated by acidfying the mixture with 1N HCl. The combined extracts were washed with water (2×15 ml), brine (2×15 ml), dried over Na2SO4, filtered and the filtrate concentrated in vac and dried. The residue was purified by flash chromatography (15%, 20% EtOAc/Hex) and then preparatory plate chromatography (50% EtOAc/Hex) to give the desired product as a viscous, hazy oil (0.400 g, 57%); 1H NMR (400 MHz, DMSO-d6) δ 1.16-1.31 (m, 8H), 1.45-1.53 (m, 2H), 1.68-1.76 (m, 2H), 3.20-3.26 (m, 4H), 3.45-3.48 (m, 2H), 3.58 (s, 3H), 3.71 (s, 2H), 4.12 (t, J=6.8 Hz, 2H), 6.37 (dd, J=0.8, 3.1 Hz, 1H), 6.95-6.99 (m, 1H), 7.06-7.10 (m, 1H), 7.32 (d, J=3.1 Hz, 1H), 7.40-7.52 (m, 6H), 7.57-7.60 (m, 2H), 7.67-7.70 (m, 2H), 7.87 (s, 2H), 8.52 (t, J=4.83 Hz, 1H); IR (film) 3300, 2800, 1750, 1630, 1540, 1470, 1220 cm−1; mass spectrum [(+)APCI], m/z 701 (M+H)+.
