실험 절차

To a solution of triphenylphosphine oxide (2.41 g) in dichloromethane (15 mL) was slowly added trifluoromethanesulfonic anhydride (1.46 mL) under ice-cooling, and the mixture was stirred for 20 min. A solution of N-[2-(benzylthio)-3,3-dimethoxypropyl]-7-{methyl[(1-methyl-1H-imidazol-2-yl)sulfonyl]amino}-1H-indole-2-carboxamide (4.4 g) and thioanisole (1.4 mL) in dichloromethane (20 mL) was added dropwise, and the mixture was stirred under ice-cooling for 1 hr. The reaction solution was diluted with ethyl acetate, washed with aqueous sodium hydrogencarbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography (ethyl acetate:hexane=3:7-4:6) to give the title compound (1.7 g, yield: 48%) as a pale-yellow oil. MS: 450 (MH+).
