Thioanisole → HCID 59135952, compound

Triphenylphosphine oxide (0.9 g) was dissolved in dichloromethane (10 mL), trifluoromethanesulfonic anhydride (0.55 mL) was added under ice-cooling, and the mixture was stirred for 10 min. A solution of N-[2-(benzylthio)-3,3-dimethoxypropyl]-5-(2-methoxyethoxy)-7-{methyl[(1-methyl-1H-imidazol-2-yl)sulfonyl]amino}-1H-indole-2-carboxamide (1.9 g) and thioanisole (0.7 mL) in dichloromethane (10 mL) was added dropwise under ice-cooling, and the mixture was stirred for 25 min, and then at room temperature for 1 hr. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate, and filtrated, and the filtrate was concentrated under reduced pressure. The residue was silica gel column chromatography (ethyl acetate:hexane=10:90-80:20) to give the title compound (620 mg, yield 39%) as a colorless oil.
