実験手順

A mixture of N-(8-indol-1-yl-octyl)-3,5-bis(3-chlorophenyl)-4-hydroxybenzamide (0.399 g, 0.68 mmol), K2CO3 (0.116 g, 0.84 mmol), and ethyl-5-bromovalerate (0.176 g, 0.84 mmol) in DMF was stirred at room temperature under nitrogen. After ˜48 h, the reaction mixture was poured into water (40 ml) and extracted with EtOAc (1×20 ml, 4×10 ml). The combined extracts were washed with water (3×10 ml), brine (2×10 ml), dried over Na2SO4, filtered and the filtrate concentrated in vac and dried. The crude product was purified by flash chromatography (alumina, hexane, 10% and 60% EtOAc/Hex) to give the desired product as a light yellow oil (0.432 g, 86%); (400 MHz, DMSO-d6) δ 1.12–1.30 (m, 15H), 1.44–1.55 (m, 2H), 1.67–1.76 (m, 2H), 1.92 (t, J=7 Hz, 2H), 3.16–3.27 (m, 4H), 3.98 (q, J=7 Hz, 2H), 4.12 (t, J=7.2 Hz, 2H), 6.38 (d, J=3.1 Hz, 1H), 6.95–6.99 (m, 1H), 7.06–7.10 (m, 1H), 7.32 (d, J=3.3 Hz, 1H), 7.40–7.52 (m, 6H), 7.56–7.59 (m, 2H), 7.68 (t, J=1.8 Hz, 2H), 7.87 (s, 2H), 8.53 (t, J=5.7 Hz, 1H); IR (film) 3320, 2940, 2950, 1730, 1630, 1540, cm−1; mass spectrum [(+)APCI], m/z 713 (M+H)+.
