Reaction Steps

To a solution of N-(8-indol-1-yl-octyl)-3,5-bis(3-chlorophenyl)-4-hydroxybenzamide (0.205 g, 0.35 mmol) in DMF (2 ml) was added ethylene carbamate (0.039 g, 0.438 mmol) and tetraethylammonium bromide (0.007 g, 0.035 mmol). The reaction mixture was warmed to 140° C. After 2.5 h, the reaction mixture was poured into water (50 ml) and extracted with EtOAc (3×20 ml). The combined organics were washed with water (3×10 ml), brine (2×10 ml), dried over Na2SO4, filtered and the filtrate concentrated in vac and dried. The residue was purified by preparatory plate chromatography (50% EtOAc/Hex) to give the product as a viscous yellow oil (0.185 g, 84%); 1H NMR (300 MHz, DMSO-d6)δ 1.25 (broad s, 8H), 1.44-1.55 (m, 2H), 1.65-1.77 (m, 2H), 3.07-3.17 (m, 2H), 3.20-3.30 (m, 4H), 4.14 (t, J=7.5 Hz, 2H), 4.44 (broad s, 1H), 6.38 (d, J=3 Hz, 1H), 6.98 (t, J=7.5 Hz, 1H), 7.09 (t, J=7.5 Hz, 1H), 7.34 (d, J=3 Hz, 1H), 7.40-7.52 (m, 6H), 7.56 7.65 (m, 2H), 7.70 (s, 2H), 7.88 (s, 2H), 8.54 (t, J=4 Hz, 1H); mass spectrum [(+)ESI], m/z 629 (M+H)+.
