실험 절차

Silver(I) oxide (0.17 g) was added to a solution of 1-(2-carbamoylethyl)-5-(N-cyclopentylmethylcarbamoyl)indole (0.70 g) and methyl 4-bromomethyl-3-methoxybenzoate (B)(0.19 g) in 1,4-dioxane (10 ml). The mixture was protected from light and stirred at 80° C. under an atmosphere of nitrogen for 12 hours. The mixture was then diluted with 1:1 v/v ethyl acetate:ether (50 ml) and filtered. The filtrate was washed sequentially with water and brine, dried (MgSO4), and evaporated. The residual yellow gum was purified by flash chromatography on silica gel (500 ml), eluting with 5:95 v/v methanol:chloroform to give the title compound (0.14 g, 39%) as a white solid; mp 189°-191° C. (d); NMR (250 MHz, DMSO-d6): 1.2-1.8(broad m, 8H, cyclopentyl), 2.2(sep, 1H, cyclopentylmethine), 3.2(t, 2H, CH2NH), 7.2(m, 2H), 7.3(broad s, 1H, CONH2), 7.5 (m, 3H), 7.7(d, 1H, H6 -indole), 8.0(s, 1H, H4 -indole), 8.3(t, 1H, NHCO).
