실험 절차

To a suspension of N-(2-hydroxyethyl)-2-iodobenzamide (5.12 g, 17.5 mmol), sodium hydrogen carbonate (5.80 g, 69.8 mmol) and tetrakis(triphenylphosphine)palladium (2.00 g, 1.73 mmol) in 1,2-dimethoxyethane (70 ml) and water (35 ml) was added methyl 3-cyclohexyl-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-6-carboxylate (7.50 g, 19.5 mmol) in five divided portions at 90° C., and the mixture was stirred for 1 hr. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was successively washed with water and saturated brine and dried over anhydrous sodium is sulfate. After filtration, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (chloroform:methanol=30:1-20:1) to give methyl 3-cyclohexyl-2-[2-(2-hydroxyethylcarbamoyl)phenyl]-1H-indole-6-carboxylate (7.40 g, yield 100%).
