실험 절차

To a solution of 3-{1-(1,3-benzodioxol-5yl)-2-[(2-methoxy-4-methylphenyl)sulfonamido]-2-oxoethyl}-6-bromo-1-methyl-1H-indole (from Example 85, 300 mg, 0.53 mmol) in 1,4-dioxane (1.5 ml) under a nitrogen atmosphere was added methoxymethyltributyl-stannane (220 mg, 0.66 mmol), followed by tetrakis(triphenylphosphine)palladium(O) (35 mg). The mixture was heated to reflux for 16 hours, and then cooled. An additional portion of tetrakis(triphenylphosphine)palladium(O) (30 mg) was added, and reflux was continued for a further 8 hours. The solvent was removed in vacuo, and the residue was flash chromatographed using a gradient elution of a mixture of 1% methanol and 99% dichloromethane, through to 5% methanol and 95% dichloromethane, to give the title compound (33 mg).
