실험 절차

A mixture of 2-cyclohexyl-8-ethenesulfonyl-1,3,8-triaza-spiro[4.5]dec-1-en-4-one (100 mg, 0.307 mmol), trifluoro-methanesulfonic acid 2-methyl-1H-indol-4-yl ester (129 mg, 0.462 mmol), tetrakistriphenylphosphine palladium(0) (35 mg, 30.2 μmol) and triethylamine (130 μL, 0.933 mmol) in 1,4-dioxane (1.5 ml) was heated with stirring at 100° C. for 18 hours. The reaction mixture was cooled, and then quenched with water and extracted with ethyl acetate. The organic layer was washed with saturated brine, and then dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to give 2-cyclohexyl-8-[(E)-2-(2-methyl-1H-indol-4-yl)-ethenesulfonyl]-1,3,8-triaza-spiro[4.5]dec-1-en-4-one (19.3 mg, 14%).
