실험 절차

Silver(I) oxide (0.30 g) was added to a solution of 5-[N-(cyclopentylmethyl)-N-methylcarbamoyl]-1-methylindole (G) (0.35 g) in dioxane (2 ml). The mixture was protected from light, stirred, and heated to reflux under an atmosphere of nitrogen for 2 hours. A solution of methyl 4-bromomethyl-3-methoxybenzoate (B) (0.33 g) in dioxane (1 ml) was added and the mixture was heated to reflux for an additional 18 hours. The mixture was then diluted with ethyl acetate and filtered. The filtrate was evaporated to give an amber gum which was purified by flash chromatography on silica gel (223 ml), eluting with chloroform to give the title compound (75.2 mg, 13%) as a white foam; partial nmr (80 MHz, CDCl3): 3.01(s, 3H, CONCH3), 3.51(br d, 2H, NCH2), 3.74(s, 3H, NCH3), 3.89(s, 3H, OCH3), 3.92(s, 3H, OCH3), 4.10(s, 2H, ArCH2), 6.81(s, 1H, H2 -indole).
